The Rijksherbarium during the war
Provedor de dados: 16
Autores: Lam, H.J.
Now that the war in Europe is over it seems appropriate, before returning to our regular duties, to devote soms words to the fate and the activities of our institution during that period. For Dutch readers many particulars may be found in the “Jaarverslagen” (Annual Reports) ; for sister-institutions abroad the following points may be of some interest. First of all it may be stated with deep gratitude that the National Herbarium of Holland has suffered no severe losses in man or material during the war.

On a new species of Axonopus from South America, with critical observations
Provedor de dados: 16
Autores: Henrard, J.Th.
Some years ago I treated a number of species of the genus Axonopus in Blumea IV, p. 510. Among them was Axonopus Fockei Henr., based upon Mez’s Paspalum Fockei, which was published in Fedde’s Repertorium XV, 1917, p. 62. I mentioned Ule’s number 8022 as identified by Mez himself being his Paspalum Fockei.

Note on subfossil teeth of Equus zebra L. from Orange free State
Provedor de dados: 16
Autores: Hooijer, D.A.
Some time ago Dr. L. D. Brongersma, curator of the Leiden Museum, entrusted me for examination some subfossil equine teeth, received from Mr. H. van Hoepen, who had found them between Glen and Mazelspoort, in Orange Free State. The teeth proved to belong all to one and the same individual, and to constitute the entire upper premolar-molar-series of the right side, almost undamaged. The importance of this find is evident, as most of the fossil or subfossil equine species from S. Africa are based on isolated teeth. An inner view of our specimen is given in pl. VI lower figure, the crown surfaces are represented in the upper figure of the same plate. It can be seen, that the P4 is the longest tooth, its height is 72 mm. The mesostyle is prominent, and...

Notes on the historical phytogeography of Celebes
Provedor de dados: 16
Autores: Lam, H.J.
In one of his papers on Malaysian Orchids R. Schleehter (1911) expresses his surprise that the flora of Celebes, though promising so much from a phytogeographical point of view, is very little known in comparison with that of the Philippines and Java and even with that of Borneo. In 1926 E. D. Merrill repeated this assumption with little less emphasis, and it is, indeed, still holding good even nowadays. I am not able to tell the reason why Celebes has been so much neglected in this respect, though it has been given ample attention by zoogeographers. Yet, botanical exploration has been carried out ever since the French scientific world cruises of the “Astrolabe” (1828) and the “Astrolabe” and the “Zelee” (1839). The more important collections have been...

Remarks on Nephrops norvegicus (L.) and its variety Meridionalis zariquiey
Provedor de dados: 16
Autores: Holthuis, L.B.
In 1935 R. Zariquiey Cenarro published a paper in the Spanish language, in which he separated the specimens of Nephrops norvegicus occurring in the Mediterranean and the southern Atlantic Ocean as a separate variety meridionalis from the typical form of the northern Atlantic. In this paper he remarks that Boas as well as Bouvier stated that the second maxillipede of Nephrops norvegicus does not bear a podobranch. When Zariquiey, however, examined material from the Catalonian coast he found that in all his specimens a podobranch was present. For comparison with the northern forms he obtained an adult male and ovigerous female from Danish waters. In these specimens indeed the podobranch was absent, the maxillipede bearing only a rounded tubercle provided...

Freedom regained

We always have thoroughly detested the mentality of those scientific periodicals which deemed it proper to introduce politics into their columns. During the war we have repeatedly been offended by the unworthy attitude of the editorial staffs of certain botanical journals of “Greater Germany” who admitted — or possibly even deliberately furthered — perorations stating not only the marvellous achievements of nazi-methods and their amazing usefulness towards the particular field of science covered by the periodical in question, but the faith and the devotion of their persons towards the sacred cause of the nazi-system. We have, as I say, not exactly admired this mentality in a scientific paper and we will not follow the example. However, too much has...

Classification of the structural elements of the secondary wood of Dicotyledons, using decimal indices for classification and identification of wood species
Provedor de dados: 16
Autores: Pfeiffer, J.Ph.; Varossieau, W.W.
1. The literature gives various methods to compile a universal scheme for the classification and identification of wood species. To attain this object a new method is now given possessing various advantages over the methods that have been used so far. 2. The wood structure is subsequently described using decimal indices. Each of five sections of features are divided into four groups, and these again in subgroups, which have been worked out by means of indices. In the treatment of various features literature data are discussed. The classification of wood species aims at obtaining a grouping which, as far as possible, links up with the botanical groupings according to natural systems. 3. On the grounds given in the introduction and the discussion, the...

Autores: Smith, J.J.
In Blumea V (1943), 316, I published a list of the Orchidaceae collected by Dr van Steenis in Atjeh. In this list a certain number of specimens were purposely omitted, on account of the fact that flowers had been preserved in alcohol, which material, however, was apparently not extant in Leiden. Under these conditions I have worked up the herbarium so far as possible from the dried specimens only. Peristylus goodyeroides (D. Don) Lndl. Gen. et Sp. Orch. (1835), 299; etc.

Variability of the female reproductive organs in Ginkgo biloba L
Provedor de dados: 16
Autores: Karstens, W.K.H.
Prom a number of Ginkgo trees kernels were examined. The investigation of the variability of the material was greatly favoured by the large number of stones, in total about 4700. In addition, one tree, grown in the Botanic Garden at Leyden, supplied the material for an investigation of the variability of the female “flowers”, in total about 1700. 1. The number of female “flowers” or rather macrosporangiophores on the brachyblasts (short shoots) proved to be most variable, showing a correlation with the age of the shoot (Table I, fig. 1). 2. A subdivision of the macrosporangiophores into a series of types proved to be possible (Table II, fig. 2-3). 3. A certain relation between the shape of the macrosporangiophore and the shape of the leafy organs from...

Autores: Holthuis, L.B.
On the initiative of Dr. A. D. J. Meeuse investigations were made on the fauna of the greenhouses of several Botanic Gardens in the Netherlands; material was also collected in greenhouses of other institutions and in those kept for commercial purposes. The isopods contained in the collection afforded many interesting species, so for instance six of the species are new for the Dutch fauna, viz., Trichoniscus pygmaeus Sars, Hyloniscus riparius (Koch), Cordioniscus stebbingi (Patience), Chaetophiloscia balssi Verhoeff, Trichorhina monocellata Meinertz and Nagara cristata (Dollfus).

The collection of Berytidae, Piesmidae, and Tingidae in the Rijksmuseum van Natuurlijke Historie is not of the same degree of completeness as that of most of the other families of bugs. Exotic insects of small size have often been neglected by our collectors, and it seems, moreover, that the Tingidae are not very abundant in the tropical regions.

A fossil gazelle (Gazelle schreuderae nov. spec.) from the Netherlands

Autores: Hooijer, D.A.
In 1944 Miss Dr. A. Schreuder sent me for identification a fossil horncore, which according to the accompanying letter came from a well-boring near Grubbenvorst (province of Limburg). It was found in a coarse sandy layer with gravel at a depth of 61.50 m below the surface; the topographic height of the latter is given as 24.53 m + N.A.P. (N.A.P. = sea-level at Amsterdam). Dr. J. F. Steenhuis, geologist to the Government Geological Foundation, informed me that deep borings for the water-supply of Central-Limburg have been made in the years 1918, 1919, and 1922 S. and S.E. of Grubbenvorst.

On the systematic position of Scotomedes (Heteroptera, Nabidae)
Provedor de dados: 16
Autores: Blöte, H.C.
In the collection of the Leiden Museum there is preserved the holotype of Scotomedes ater Stål. I was much surprised to discover that Velocipeda biguttula Reut. is a synonym of it. Distant described another Scotomedes-species in his "Fauna of British India" under the name: Godefridus alienus, bringing it to the Reduviidae, subfam. Apiomerinae. This was a reason for derision by Reuter, who cited it as an instance of Distant's less trustworthy scientific performances (Reuter, 1905). However, though it seems to have been "bon ton" to ridiculize Distant's views, we are not accustomed to neglect Stål's, and I was much interested to know why Stål had placed Scotomedes without hesitation into the Nabidae, as other authors have been of a so much different opinion....

Contributions to our knowledge of the flora of Celebes (Coll. C. Monod de Froideville) and of some other Malaysian Islands
Provedor de dados: 16
Autores: Lam, H.J.
The following notes are mainly based upon a small but interesting collection of plants, made in 1937—1939 by Mr C. Monod de Froideville, Civil Service Officer in the Netherlands Indies, during his extensive trips in the southern and central parts of the island of Celebes. His hobby was the study of Leguminosae and about half of his collection consists of representatives of that natural order. For several reasons, however, they have been left out of the present paper, for one thing since Mr Monod is intending to deal with them later on himself, a task, which circumstances unfortunately prevent him from accomplishing at present; and secondly since they promise geographically less important results than most other families, many of them being anthropochorous....

In a previous number of this volume (Blumea V, nr. 1, 1942, p. 66—80), one of the junior writers of the present paper published an account of nomenclatorial changes concerning javanese Verbenaceae. This paper was written as a supplement to a larger work by the senior writer, who has for long years devoted most of his activities to the study of the flora of Java, on which it was his privilege to publish some more or less extensive papers, all of them in the Dutch language 2). These publications may be considered materials for a Flora of Java.

Two new Bird-records from Surinam (Dutch Guyana)

Autores: Voous Jr., K.H.
Falco peregrinus anatum Bonaparte Adult (evidently ♀), Surinam. Wing 363, tail 170, tarsus 53, culmen from cere 24 mm. Together with other Surinam bird-skins, the specimen was sent to Harlem (Holland) in 1899 for exhibition at the "Koloniale Westindische Tentoonstelling". It is now in the collection of the Colonial Institution at Amsterdam. The North-American Peregrine Falcon has not yet been recorded from all three Guyanas: Chubb (1916) does not mention it from the British Colony, nor the brothers Penard (1908) from Surinam, nor Von Berlepsch (1908) from Cayenne. As the bird has been recorded several times from Trinidad (off the coast of Venezuela) (cf. Roberts, 1934) and a juvenile specimen from Brazil is preserved in the Zoological Museum at Berlin...

Een Vondst van de Witten Dolfijn, Delphinapterus leucas (Pall.), in Nederland
Provedor de dados: 16
Autores: Deinse, A.B. van; Junge, G.C.A.
In 1936 ontving het Rijksmuseum van Natuurlijke Historie door bemiddeling van Dr. L. D. Brongersma een drietal wervels van een dolfijnachtige, afkomstig uit een jeugdcollectie van J. IJzerdraat. Helaas waren de gegevens, die wij, dank zij Dr. Brongersma, over de herkomst van deze wervels konden achterhalen, vaag. De wervels waren ± 1919 gevonden aan het strand tusschen Zandvoort en IJmuiden. Het is jammer, dat er niet meer gegevens zijn, daar door vergelijking bleek, dat we te doen hebben met den tweeden halswervel (draaier), eersten borstwervel en een (waarschijnlijk tweeden) lendenwervel van een Witten Dolfijn, een soort, die tot nu toe niet in ons land was geconstateerd. Het exemplaar was waarschijnlijk nog niet geheel volwassen, daar de epiphysen van...

De Staart der Cetacea en eenige Gevallen van lintvormige Staarten bij Phocaena phocoena (L.)
Provedor de dados: 16
Autores: Deinse, A.B. van.
Bij de beschrijving en (of) de determinatie van Cetacea speelt de staart geen belangrijke rol. Toch is er een vertegenwoordiger dier orde te noemen, waarbij de staart er zoo karakteristiek uitziet, dat hierdoor alleen reeds geslacht en soort volkomen zijn bepaald. Ik bedoel Megaptera novaeangliae (M. nodosa, M. longimana, M. boops), de Humpback whale der Engelschen. De achterrand van de staartvin van dit dier is van een soort franje voorzien en dit kenmerk heeft géén andere cetacee. E. Mohr, Hamburg (1931, blz. 125, pl. 73) beeldde een foto af van een in Duitschland geschilderde Megaptera uit 1766, gemaakt naar een gestrand individu, waar de staartfranje reeds duidelijk is weergegeven. In 1889 behandelde J. Struthers uitvoerig de anatomie van de Humpback...

Professor I. Q. van Regteren Altena was zoo vriendelijk mij een aantal teekeningen ter beschikking te stellen, die eens aan het huis Plantijn moeten toebehoord hebben. Immers, sommige daarvan hebben gediend als voorbeeld voor houtsneden in den Herbarius von Dodonaeus van 1618, gedrukt „t'Antwerpen in de Plantynsche Druckerye van Balthasar Moretus" (zie Engel, in: Ned. Kruidk. Arch. 53, 1943, p. 46-55). Wanneer men de fraaie teekeningen vergelijkt met de reproducties in het Cruydtboeck, is het opvallend, dat de teekeningen losser, zwieriger en natuurlijker zijn, terwijl de houtsneden allerlei wijzigingen vertoonen, die klaarblijkelijk aangebracht werden ten einde de figuur in het formaat van het houtblok te doen passen.

Análise estatística da distribuição de Poisson
Provedor de dados: 43
Autores: Gurgel,J. T. A.
The general properties of POISSON distributions and their relations to the binomial distribuitions are discussed. Two methods of statistical analysis are dealt with in detail: X2-test. In order to carry out the X2-test, the mean frequency and the theoretical frequencies for all classes are calculated. Than the observed and the calculated frequencies are compared, using the well nown formula: f(obs) - f(esp) 2; i(esp). When the expected frequencies are small, one must not forget that the value of X2 may only be calculated, if the expected frequencies are biger than 5. If smaller values should occur, the frequencies of neighboroughing classes must ge pooled. As a second test reintroduced by BRIEGER, consists in comparing the observed and expected error...

Estudos genéticos sôbre o milho tunicata
Provedor de dados: 43
Autores: Brieger,F. G.
The study of pod corn seems still of much importance from different points of view. The phylogenetical importance of the tunicate factor as a wild type relic gene has been recently discussed in much detail by MANGELSDORF and REEVES (1939), and by BRIEGER (1943, 1944a e b). Selection experiments have shown that the pleiotropic effect of the Tu factor can be modified very extensively (BRIEGER 1944a) and some of the forms thus obtained permitt comparison of male and female inflorescences in corn and related grasses. A detailed discussion of the botanical aspect shall be given shortly. The genetic apect, finally, is the subject of the present publication. Pod corn has been obtained twice: São Paulo Pod Corn and Bolivia Pod Corn. The former came from one half...

Competição entre megaspórios em milho
Provedor de dados: 43
Autores: Brieger,F. G.
The experiments reported were started as early as 1933, when indications were found in class material that the factor for small pollen, spl, causes not only differences in the size of pollen grains and in the growth of pollen tubes, but also a competition between megaspores, as first observed by RENNER (1921) in Oenothera. Dr. P. C. MANGELSDORF, who had kindly furnished the original seeds, was informed and the final publication delayed untill his publication in 1940. A further delay was caused by other circunstances. The main reason for the differences of the results obtained by SINGLETON and MANGELSDORF (1940) and those reported here, seems to be the way the material was analysed. I applied methods of a detailed statistical analysis, while MANGELSDORF and...

Efeitos do arsênico sôbre a cultura do algodoeiro em terra arenosa
Provedor de dados: 43
Autores: Coury,Tufi; Ranzani,Guido.
The authors studied the action of arsenic, in the form of lead arsenate and sodium arsenite, on cotton in white sandy soil of Piracicaba, State of S. Paulo, Brazil. The experiment was carried out in Mitscherlich pots, applying increasing quantities of the above mentioned compounds. The following conclusions were reached: sodium arsenite is more toxic than lead arsenate. 48 pounds per acre of lead arsenate and 16 pounds per acre of sodium arsenite reduced the vegetative development and the production of cotton. The roots were more seriously affected than the aerial parts. Sandy soils were sensitive to arsenic toxicity. The arsenic mobilization in the soil seems to depend upon factors such as, the a- cidity, the concentration of Fe2O3, CaO, P2O5 and soil...

Espiguetas de dois grãos no milho
Provedor de dados: 43
Autores: Cutler,H. C.
A morfologia, ocorrência, utilidade e genética das flores funcionais inferiores em espiguetas de milho, são examinadas ligeiramente. Em regra, somente a flor superior em cada espigueta numa espiga de milho se desenvolve e contém um grão, porém nos exemplos em foco a flor inferior se desenvolve tão bem como a superior. O embrião no milho geralmente se acha voltado na mesma direção que a ponta da espiga, ao passo que o embrião do grão proveniente da flor inferior se volta na direção da base. São raras, não só na América do Norte e Central, como na maior parte da América do Sul, as espigas nas quais os grãos provêm da flor inferior das espiguetas, constituindo uma exceção o milho doce Country Gentleman, no qual se encontram grãos em ambas as flores na maioria...

Apenas em uma variedade - Co. 312 - tivemos um resultado duvidoso. Em F 29-7 nota-se que o erro nas' canas florescidas é maior que nas não florescidas, o que parece indicar uma tendência a maior instabilidade do Brix com o florescimento. A diferença entre os dois erros é, poréxn, de significação duvidosa, embora o valor de P exceda bastante o limite de 5% de probabilidade, sem atingir o de 1%. 2 - Análise dos redutores Houve uma diferença sem significação em F 29-7 e Co. 285.

1) The first part deals with the different processes which may complicate Mendelian segregation and which may be classified into three groups, according to BRIEGER (1937b) : a) Instability of genes, b) Abnormal segregation due to distur- bances during the meiotic divisions, c) obscured segregation, after a perfectly normal meiosis, caused by elimination or during the gonophase (gametophyte in higher plants), or during zygophase (sporophyte). Without entering into detail, it is emphasized that all the above mentioned complications in the segregation of some genes may be caused by the action of other genes. Thus in maize, the instability of the Al factor is observed only when the gene dt is presente in the homozygous conditions (RHOADES 1938). In another...

A Composição do caldo de cana de açúcar: Contribuição para o estudo dos efeitos de adubações
Provedor de dados: 53
Autores: Sampaio,S. C.
Analisando-se o que vimos de expor, para as condições experimentadas, verifica-se o seguinte : 1. Os diversos elementos fertilizantes comumente aplicados às culturas cana vieiras exerceram alguma influência sôbre a rigueza e a pureza do caldo. 2. Os adubos nitrogenados, em geral, deprimiram o teor em sacarose do caldo, assim como prejudicaram a sua pureza, e isto se dá tanto nas terras coloridas como nas arenosas, claras. 3. Os fertilizantes potássicos, em conjunto, favoreceram a formação do açúcar no caldo, não se notando o mesmo efeito nítido na melhoria da pureza do mesmo. Nas terras roxas ou falsa-roxas a sua ação favorável foi acentuada tanto para o enriguecimento do caldo como para melhorar a pureza dêste ; mas, nas terras arenosas, claras, as cousas...

Autores: Brieger,F. G.; Moreira,Sílvio.
The English resumé is given in a different form from the Portuguese "conclusões". In the former we gave mainly the results which may be of general interest, explaining the tables (quadros) and the procedure of statistical analysis, while in the other the properties of the different rootstocks are discussed in detail since they are of immediate local interest. 1. In a previous publication, Moreira (19) explained the layout and the first results of an experiment, under way since 1936 in the Limeira Exp. Sta., on the influence of twelve different types of Citrus rootstocks on three scion varieties : the oranges "Baianinha" and "Pera" and the grape-fruit "Marsh Seedless". We report here three main results obtained during the first six years of the experiment:...

Autores: Brieger,F. G.
1) The present paper deals with variations in the structure of the inflorescences of the Maydeae Americanae, especially of the ear of Zea Mays, which came under observation during our genetical studies during the last 10 years. Care was tauken to include only such structures which were observed frequently and had in general an aspect which could not be described as a pathological abnormality, but rather as a reversion to a phylogenetically primitive type or as a new form. The aberrations may be summarized as follows: a) Individual flowers. Eeversion to the hermaphrodite state of the usually unisexual flowers in Maydeae were described. Such flowers are however already so well known that no details need to be given. b) Many flowered spikelets. The spikelet...

Estudos químico-espetrográficos e roentgenográficos da hidromagnocalcita
Provedor de dados: 53
Autores: Paiva Netto,J. E. de; Catani,R. A.
In the vicinity of the city of Rio Claro (S. Paulo, Brazil) occurs a type of calcareous rock which was studied chemically, spectrographically and roentgenographically. The roentgenograph investigations showed that the rock belong to the hydromagnocalcite, CaCO3+Mg(OH)2, and not the dolomitic type as it was considered up to the present. The first four roentnogramms show the crystalline structure of the mineral and the fifth the crystalline structure of the synthetic mixture of CaCO3+Mg(OH)2 in the proportions indicated by the chemical analysis of table I. The spectrographical analysis revealed the presence of: Mn, Fe, Al, Sn, Cu, Na, Sr, Zn and Pb, the percentages of which reached a value less than 0,1%.

This paper reports a preliminary study of four sweet potato varieties, Russia, Napoleão, Roxa and Viçosa, carried cut in 1939-40 at the Central Experiment Station, Instituto Agronomico. Comparative plots of each variety were harvested after 3, 4, 5, 6, 7, 8 and 9 months of vegetation, the product being then examined for the following characters : a) Total yield b) Number of roots c) Average weight of the potates d) Production of different grades e) Qualities of the fresh roots f) Culinary value of the sweets potatoes The yield after three months of vegetation was very small for the four varieties, but increased considerably in the later harvests. The variety Napoleão attained its highest yield after six months, being early; Roxa yielded most after seven...

Genética de coffea: VIII - Hereditariedade dos caracteres de C. Arabica I. var. Anomala K. M. C.
Provedor de dados: 53
Autores: Krug,C. A.; Carvalho,Alcides.
No presente artigo, após uma descrição detalhada dos caracteres da variedade anomala de C. arabica, são relatados os resultados da sua análise genética. Concluiu-se que se trata de uma forma recessiva em relação ao tipo normal da espécie, propondo-se para o único par de gens responsáveis o símbolo an an. A ação dêste par de gens é notável, afetando a quase totalidade dos caracteres da planta, como : porte, ramificação, fôlhas, flores, frutos e sementes. O F1, normal x anômala, demonstra dominância praticamente total do tipo normal, manifestando-se a presença do alelo recessivo apenas esporadicamente, deformando, possivelmente sob ação de determinados fatôres do meio ambiente, ou em consequência de alguma anomalia citológica, os ápices de alguns pares de...

Autores: Boock,Olavo José.
1 - As experiências relatadas no presente trabalho se referem ao emprêgo de diferentes adubos fosfatados na cultura da batata (S. tuberosum L.) e conduzidas em Campinas, Taubaté e Joanópolis, em 1940 e 1944. 2 - As análises sumárias das terras indicaram variações do fósforo, desde muito fraco (Joanópolis), regular (Campinas) até ótimo (Taubaté) . 3 - As menores produções foram obtidas dos canteiros sem adubo. 4 - O emprêgo ùnicamente de adubos azotados mais potássicos, pràticamente, não determinou aumento de produção sôbre os "sem adubo". 5 - O acréscimo de adubos fosfatados aos azotados e potássicos causou um aumento altamente significativo de produção. 6 - Os canteiros em que além dos adubos azotados e potássicos, incluímos o Superfosfato apresentaram em...
