SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

The present publication is intended to be a monograph on the family of Burmanniaceae. It is divided into three parts: General Part, Critical Part and Taxonomical Part. The first part, General Part, contains general remarks on the taxonomy, distribution and use of the family. The second part, Critical Part, contains general and geobotanical remarks on the genera of the family, whereas the third part, the Taxonomical Part, gives the determination keys to the tribes, subtribes, genera, sections, subsections and species, the description of these groups with literature, distribution and the indications of the types. New varieties, species and larger groups are described in the taxonomical part in foot-notes.

Opmerkingen betreffende de interpretatie van de bloemmorfologie bij het speenkruid

Ano: 1938

URL: http://www.repository.naturalis.nl/record/534971

An outline of the possible homologies of the calyx and corolla of the Lesser Celandine on the hand of the flower morphology of both Anemone and Hepatica, and Ranunculus is given. The possible affinities of the species are discussed. The author defends a homology of its calyx to that of Hepatica and to the involucre of Anemone, and, at the same time, a homology of its corolla to that of Ranunculus and to the nectaries in a number of other genera of Ranunculaceae. The author rejects a placing of the species in the genus Ranunculus (as R. ficaria L.) and is in favour of a placing in the genus Ficaria (F. verna Huds.). Pollenmorphological data are, more or less in accordance with this view.

Notes on the Marantaceae of Suriname

Ano: 1971

URL: http://www.repository.naturalis.nl/record/527717

Jonker-Verhoff, A.M.E.; Jonker, F.P..

The list of Marantaceae published by PULLE (1906) comprises 20 species belonging to 6 genera, the largest genus being Calathea with 8 species. It was found, however, that one of the species does not belong to the family: investigation of the type of Calathea strobilifera (Miq.) Koern., viz. Kegel 1469 [GOET], showed that it pertains to Renealmia strobilifera Poepp. et Endl. (Zingiberaceae). The record of another species, Calathea allouia (Aubl.) Lindl. appeared to be based on a misidentification: the collection Focke 893 cited under this name by PULLE (1906) belongs to C. grandis O. G. Peters. Later on PULLE (1909) recorded the occurrence of one species more of this family in Suriname, viz. Myrosma polystachya Pulle, a new species. Since then no further...

Les Géosiridacées, une nouvelle famille de Madagascar

Ano: 1956

URL: http://www.repository.naturalis.nl/record/534947

En 1894, H. Baillon (Bull. Mens, de la Soc. Linn. de Paris II, p. 1149) décrit une nouvelle plante de Madagascar, Geosiris aphylla, qui d’après sa couleur et son aspect général faisait penser à la famille des Burmanniacées. Mais, comme il remarquait, non seulement que les 3 anthères ne se conformaient pas à celles des Burmanniacées dans leur forme, les anthères sont superposées aux sépales et non aux pétales ainsi qu’en est le cas chez les Burmanniacées qui possèdent 3 étamines. Selon la forme et selon la place des étamines Baillon pensait alors avoir à faire avec une représentante de la famille des Iridacées dépourvue de chlorophylle. La construction des fleurs et surtout celle du gynécée se rapprochent le plus fortement au groupe d’ Aristea et ses...

Notes on the Araceae of Suriname II

Ano: 1939

URL: http://www.repository.naturalis.nl/record/535224

Jonker-Verhoef, A.M.E.; Jonker, F.P..

After the publication of the Araceae in the Flora of Suriname 1.2 (1953), p. 1-80, a number of rare and new species have been collected. Some of these were collected by Dr. J. Lindeman between 1953 and 1955, the remaining by the present authors, who visited Suriname from November, 1955, to March, 1956. Field observations by the authors clearly indicated the fragmentary status of our knowledge of Suriname Aroids. The reasons for this are to be sought in the difficulties involved in collecting and preserving. Also, a number of species may not flower over a period of several years. The inflorescences of many lianas are often almost inaccessible. A source of confusion is the variability in the leaves of a species. The following is an enumeration of species...

Remarks on the South-American species of the genus Cassipourea (Rhizophoraceae)

Ano: 1959

URL: http://www.repository.naturalis.nl/record/534857

Though an excellent, critical monograph of the genus Cassipourea was published some years ago by ALSTON (in Kew Bulletin, 1925, p. 241—276), I should like to make a few remarks on the South-American species of this genus as my revision for PULLE’s Flora of Suriname III.2 has brought to light a few new facts. It will also give me an opportunity to refer to a publication of BRIQUET on some American representatives of this genus (in Candollea IV, 1931, p. 342—350), which disagrees with regard to a number of species with ALSTON’s interpretations. The species which covers the largest area is the chiefly West-Indian C. elliptica (Sw.) Poir. Formerly also a number of West- Brazilian and Peruvian specimens were referred to it, but ALSTON pointed out that these...

Zu meiner Bearbeitung des surinamischen Materials der Gentianaceae für die von Pulle herausgegebene „Flora of Surinam” gehören nog einige kritische Bemerkungen. Ich muszte z.B. in einigen Fällen von der von Gilg in Engler und Prantl, Nat. Pflanzenfamilien gegebenen Einteilung der Gattungen und deren Umgrenzung abweichen. Auch stellte es sich heraus, dasz sich unter dem Material eine neue Art befand, deren Beschreibung und Abbildung unten folgen.

Palynology and The Netherlands

Ano: 1936

URL: http://www.repository.naturalis.nl/record/534785

A description is given of the history of the development of palynology in The Netherlands. This development is traced from the appearance in 1777-1779 of the book Katechismus der Natuur by J. F. Martinet, through the increased interest, begun in the 1920’s with the appearance of a thesis by Miss B. Polak on the investigation of peat bogs in the western Netherlands, to the culmination with the establishment of palynological divisions in several universities and other institutions in The Netherlands.

Notes on the Araceae of Surinam III

Ano: 1967

URL: http://www.repository.naturalis.nl/record/534838

Jonker-Verhoef, A.M.E.; Jonker, F.P..

After the publication of part I and part II of this series a number of Aroids were collected in the interior of Surinam, chiefly by A. G. H. Daniels and F. P. Jonker during an expedition to the Emma Range in 1959. The following is an enumeration of species collected for the first time in Surinam in addition to records of recollections of rare taxa and critical notes on misinterpreted or confused species. The present authors also examined those specimens collected by J. van Donselaar and W. A. E. van Donselaar-ten Bokkel Huinink (1958/59), K. U. Kramer and W. H. E. Hekking (1960/61), J. G. Wessels Boer (1963), J. P. Schulz (1963) and P.A. Florschütz and P. J. M. Maas (1964/65).

The genus Jussieua L. (Oenotheraceae) in Suriname

Ano: 1966

URL: http://www.repository.naturalis.nl/record/535007

Of the family Oenotheraceae the genus Jussieua is the only one occurring in Suriname. The peculiar Oocarpon torulosum (Arn.) Urb., which has been recorded from Amazonian Peru, Brazil, British and French Guiana, Cuba and Santo Domingo, has up till now not been collected in the colony, but on account of its presence in the neighbouring countries it is there also to be expected. As for the name of the only Suriname genus, it was spelled by LINNAEUS in Genera Plantarum, ed. I (1737), p. 126, Jussieua but afterwards in his Flora Zeylanica (1747), p. 75, changed in Jussiaea.

The genus Rhizophora in Suriname

Ano: 1942

URL: http://www.repository.naturalis.nl/record/535162

The peculiar distribution of the species of Rhizophora (Rhizophoraceae) is wellknown. Floras and manuals usually mention one western species — R. mangle L. — that occurs both in the coastal regions of tropical and subtropical America and in the corresponding habitats of west tropical Africa, and an eastern species — R. mucronata Lam. — occurring both in tropical Asia and in east tropical Africa. It is also well-known that a few other species occur in tropical Asia; a recent revision has been given by HOU (1958). G. F. W. MEYER (1818) described from British Guiana a second American species, R. racemosa, differing in the inflorescence which is forked and 2-flowered in R. mangle and much-branched in R. racemosa. ENGLER (1876) regarded this species as a...

A Palynological investigation of the Lower peat in the Province of Friesland, the Netherlands

Ano: 1959

URL: http://www.repository.naturalis.nl/record/534985

Donselaar, J. van; Jonker, F.P..

Up till now the lower deposits of peat (in Dutch: veen-op-groterediepte = peat at greater depth) have been investigated in the Netherlands mainly in the Western part of the country, viz. in the provinces of Noord-Holland, Zuid-Holland and Zeeland. The analyses have shown that the development of this, now comparatively well known peat layer must have begun either in the second half of the boreal period or else in the beginning of the atlantic one, and that it must have come to an end in the first half of the latter. Among the earlier investigators the botanist Mrs VERNEER-LOUMAN and some geologists had arrived at the conclusion that the sudden transgression of the North sea which made an end to the formation of peat, took place in the boreal period, and hat...

Notes on the Araceae of Suriname

Ano: 1952

URL: http://www.repository.naturalis.nl/record/535091

Jonker-Verhoef, A.M.E.; Jonker, F.P..

The list of Araceae published in 1906 by A. A. PULLE in his “Enumeration of the Vascular Plants known from Surinam” comprises 39 species belonging to 14 genera, the largest genera being Anthurium with 7 species and Philodendron with 12 species. It was found that one of these 39 species was included by mistake, for the specimen Wullschlaegel n. 1764, which is the type of Spathiphyllum blandum Schott, was erroneously assumed to have been collected in Suriname. Already in 1908 TRESLING had collected a species that was not listed by PULLE, viz. Dieffenbachia picta (Lodd.) Schott.

Heyerdahl’s kon-tiki theorie en de ethnobotanie

Ano: 1938

URL: http://www.repository.naturalis.nl/record/525423

Misschien wel het meest gecompliceerde probleem van de vele waarvoor een nieuw benoemde hoogleraar zich geplaatst voelt, is het onderwerp van zijn oratie. Binnen de wetenschap, die hij voortaan in de kringen van zijn universiteit mag uitdragen, zijn uiteraard tal van vraagstukken het onderwerp van actuele discussies, en een aantal van deze problemen zal zijn warme belangstelling hebben. Dikwijls zal hij partij gekozen hebben in een aantal strijdvragen en het ligt voor de hand dat de verleiding groot is om de gelegenheid van zijn inaugurele rede aan te grijpen en zijn standpunt met klem van argumenten uiteen te zetten.

Über due flora des mindel-riss-interglazials in den Niederlanden

Ano: 1960

URL: http://www.repository.naturalis.nl/record/534995

Florschütz, F.; Jonker, F.P..

Die Pflanzendecke unseres Landes hat während des Quartärs grosse Änderungen erlitten. Dies wird besonders deutlich beim Vergleich der limburgischen fossilen Flora, wie sie in einer vortrefflichen Arbeit des Ehepaares REID (Lit. 1) beschrieben ist, mit der gegenwärtig einheimischen Vegetation. Im allgemeinen wird die erwähnte Flora für jungtertiär gehalten, jedoch ist ihre Stelle im Pliozän umstritten. Von den ungefähr 240 Phanerogamen, von welchen sich Reste im Ton von Reuver, Swalmen und Brunssum vorfanden, sind laut der Berechnung von E. M. REID nur 12% heute indigen und 88% exotisch; mehr als die Hälfte der letzteren sind identisch mit rezenten sino-amerikanischen Arten (Lit. 2).

De natuurwetenschappelijke expeditie naar de emmaketen in Suriname, juli-oktober 1959

Ano: 1942

Jonker, F.P.; Wensink, J.J..

An account is given of a scientific expedition to the Emma Range in Dutch Guiana. The expedition left on 10 July 1959 from Paramaribo, and after five days reached the base camp on the Toekoemoetoe creek, a tributary of the upper Saramacca River. From here the expedition proceeded by foot to the Emma Range. The main camp was situated at the foot of the range, at a height of 325 m. Two subsidary camps were set up at the north and south of the range respectively. On the 28th October the expedition returned to Paramaribo.

Revisie van de Nederlandse Gentianaceae, I. Centaurium Hill

Ano: 1960

URL: http://www.repository.naturalis.nl/record/534744

De moeilijkheden, die optreden bij het determineren van de Nederlandse vertegenwoordigers van het genus Centaunum (= Erythraea), waren voor mij aanleiding het Nederlandse materiaal eens aan een revisie te onderwerpen. De Franse flora’s b.v. vermelden een aantal soorten, waarvan het voorkomen in Nederland niet onmogelijk is (lit. 1, 2, 9). De bewerkingen van het Britse materiaal door WHELDON and SALMON in 1925 (lit. 15) en door GILMOUR in 1937 (lit. 4) wezen uit, dat ook in Engeland tal van soorten en variëteiten voorkomen, die voor Nederland onbekend zijn. Tenslotte verscheen in 1940 een bewerking van het Scandinavische materiaal van C. vulgare door STERNER (lit. 12), waarbij eveneens tal van vormen voor de dag kwamen en ook een voor Nederland onbekende...

Cornus mas L. als Nederlands indigeen en de noordgrens van het soortareaal

Ano: 1950

URL: http://www.repository.naturalis.nl/record/534818

Burgh, J. van der; Jonker, F.P.; Bunnik, F.P.M.; Landsmeer, D..

The discovery of two localities of Cornus mas in the farthest south of the Netherlands induced the authors to study the distribution of the species in Northwest Europe. They arrived at the conclusion that the species is indigenous in the Netherlands, in the southern part of the calcareous district i.e. the uttermost south of the province of Limburg. A line running diagonally through Belgium from the Straits of Dover to Maastricht; in the Netherlands from Maastricht to Aachen and in Germany from Aachen to Gottingen is considered to be the northern boundary of the species area in Western Europe.
