Notes on Guiana Myrtaceae III

Amshoff, G.J.H..

What KIAERSK wrote in 1893 in the preface of his “Enumeratio Myrtacearum Brasiliensium” is still largely valid. It is often most difficult to define a species belonging to this family, not only because, in the absence of ripe seeds, the genus is not easily ascertainable, but also because of the strong variability shown by the vegetative characters. Thanks to the examination of the rich Guiana material preserved in the herbaria of Genève, Kew, Leiden, New York, Paris and Utrecht, I have usually been able to delimit the species in a satisfactory way; their allocation to a definite genus, however, is often a difficult problem. During the preliminary stage of this investigation, which was interrupted by the war, it was of great advantage to me that I could...

Notes on the Flora of Java, V. Identification of the new species and combinations proposed by C. P. Thunberg in the Florula Javanica by L. Winberg and F. O. Widmark (1825)

Backer, C.A.; Bakhuizen van den Brink Jr, R.C.; Steenis, C.G.G.J. van.

Though the new names published in Thunberg’s “Florida” have been entered in the Index Kewensis, few botanists have tried to verify the status and synonymy of the new species proposed in this 2-thesis booklet. Thunberg’s names were entered in Juel’s “Plantae Thunbergianae” (1918, 412 pp.). The diagnoses are generally too short and vague to allow a definite opinion. Only Schott, Mueller Arg., and F. E. Wimmer have examined material of resp. the Araceae, Euphorbiaceae, Campanulaceae.

Java Suiker (1930) 203—209; Aimshoff in Blumea 5 (1942—1945) 515—517. Miss Dr G. J. Amshoff started the revision of the Javanese Urticaceae, but left the definitive preparation to me. Urtica dioica L. and U. urens L. have been erroneously recorded for Java (Miquel, Fl. Ind. bat. 1², 1859, 227; Koorders, Exk. Fl. Java 2, 1912, 126). To my knowledge no specimens were ever collected there nor elsewhere in the Malay Archipelago.

On lower tertiary Mollusca from S.W. and Central Celebes

Ano: 1950

URL: http://www.repository.naturalis.nl/record/526256

1) In the “Rijksmuseum van Geologie en Mineralogie”, Leyden, there is a small collection of Lower Tertiary mollusca from S.W. Celebes which allows of comparison with Abendanon's Celebes fossils described by Dollfus and kept in the “Instituut voor Mijnbouwkunde”, Delft. The present note deals especially with Turritella krooni Dollfus (S.W. Central Celebes; said to be of Cretaceous age), a new subspecies T. krooni batukuënsis (S.W. Celebes; Eocene), and the new T. krooni kalosiensis, formerly described as T. cf. angulata Sowerby and T. cf. assimilis Sowerby (S.W. Central Celebes; probably of Upper Eocene age, formerly considered to be of Oligocene age).

Pliocene Mollusca from a coral limestone of a hill near Sekoerau, E. Borneo

Ano: 1950

URL: http://www.repository.naturalis.nl/record/505646

The present paper deals with a small collection of Neogene fossils which has been made by the geologist Dr. M. Schmidt in the Sangkoelirang area 1), East Borneo. The locality is defined in Gerth’s (1923) and Krijnen’s papers (1931, loc. no. 175, p. 535). It must be stated here that this locality has been mentioned incorrectly in literature, viz., as “Hill near Sekoerau” instead of “Coral limestone, Hill near Sekoerau”. Dr. Schmidt’s collection, which was sold to the Leyden Geological Museum in 1920 — about twenty years after being made — contains two different faunas from Sekoerau: vide infra.

On probably young miocene fossils from the coal concession Batoe Panggal, near Tenggarong (Samarinda), Eastern Borneo

Ano: 1950

URL: http://www.repository.naturalis.nl/record/505745

In the collections of the Leyden Geological Museum is a set of fossiliferous clay-stones which was long ago collected by the mining engineer Hulshoff-Pol in the coal quarries of Batoe Panggal 1), Eastern Borneo. He presented the collection in 1902 to Dr M. Schmidt, who at that time was making geological investigations in Borneo. After Dr Schmidt’s appointment to a professorship in Stuttgart, the fossil collections made by him in Borneo were acquired by the Leyden Geological Museum (1920). Fig. 1 roughly indicates the locality of Batoe Panggal, while Fig. 2 depicts the delta area of the Mahakkam or Koetei river and its neighbouring areas. The dotted area is again represented in Fig. 3 below.

On fossil Mollusca from the island of Mandul, East-Borneo

Ano: 1950

URL: http://www.repository.naturalis.nl/record/505858

This paper presents the results of the examination of a fairly big collection of mollusca from the island of Mandul, north of Tarakan, East-Borneo. The material was collected by Dr. Van Holst Pellekaan while investigating the geology of Mandul in the service of the “Bataafsche Petroleum Maatschappij” (Royal Dutch/Shell). It was sent to Prof. K. Martin of Leyden for closer examination, and afterwards was embodied into the collections of the Leyden Geological Museum. Prof. Martin recorded the results of his preliminary examination, which excluded the bivalves, in a report to the “Bataafsche”, dated 12th January 1917. He came to the conclusion that the fossils were of a Pliocene age.

Two groups of 51 one day chickens were placed on a diet in which 10% of corn meal in the ration has been substituted by cane molasses. It was found that in the diet with cane molasses the chickens had a better development and the difference was found to be statistically significant. Since corn meal is more expensive than cane molasse, that substitution is recommended.

Bergman, R.A.M..

GENERAL CHARACTER Natrix vittata, the striped swimmer, is a harmless little snake, about half a meter long and as thin as a little finger, living in Java on coastal plains and in the hills up to 1200 m above see level. In a given area she will be very common but in adjacent regions, which to us may present exactly the same character of humidity, altitude, temperature, vegetation, etc., there will be only very occasionally a Natrix vittata among the catch (de Haas, 1941a). Even in the field she is easily recognisable, as she will lift her head high enough to show the curious design of her ventral shields. If there is an opportunity for examining the snake more closely, the twin small white spots on the head shields will identify her. The colour of the body...

Bergman, R.A.M..

MATERIAL AND PROBLEM For the investigation of the anatomical pattern of Natrix vittata, the same material was used as for the description of the life of this snake. A preliminary question was whether both groups from Surabaia and from Tjimahi may be used for statistical treatment as a single unit or if they represent different varieties. The animals are easily recognisable and there is no outward sign which would indicate a difference between the group from the eastern coastal plains and the one from the western hills although the distance between both localities is about 800 km. The range of the body length is for both groups the same, for adult males in Surabaia 341-441 and in Tjimahi 346-457, and for females 392-560 and 395-555. In none of the other...

Bodlaender, K.B.A..

This paper deals with the investigation of soil samples taken near Terhorne on the North-East shore of the “Sneeker Meer”, an expanse of water in the province of Friesland. (see fig. I) According to the geological map, the peat around this large body of water is covered by an 1—4 dm thick layer of young marine clay, but at the place where our samples were taken, the peat reaches the surface. A series of samples were collected from the whole depth of this peat-deposit (see diagram I). The surface lies here 0.35 m below the level of the sea. (As the sealevel is taken the N.A.P., the average height of the water level at Amsterdam.) At a depth of 2.15 or 2.20 m the borer reached the underlying sand. It proved impossible to penetrate with the borer used by us...

Boock,O. J..

Cotton meal was studied as a source of nitrogen for Irish potatoes in six trials carried out in five localities of the State of São Paulo. Six fertilizer mixtures, containing equal amounts of superphosphate and potassium sulphate, and varying proportions of cotton meal and ammonium sulphate, were compared. The results of these tests indicated that the two sources of nitrogen increased the potato yield ; and that when the amount of soil moisture is satisfactory, nitrogen may be supplied by cotton meal alone or in mixture with ammonium sulphate. In one trial the cotton meal had no effect on yield, whereas the ammonium sulphate was effective. Also no injury to the plants resulted from application of cotton meal. Based on the results of these trials it was...

Boock,O. J..

The behavior of the Irish potato variety "Eigenheimer" in the State of São Paulo has been studied. This variety grows well under the soil and climatic conditions present in potato areas of this state. Eigenheimer is an early maturing variety and a good yielder. The tubers sprout readily in storage, permitting two plantings in a year to be made with same seed. It is susceptible to virus diseases, early and late blight, bacterial wilt, common scab, and root-knot nematode. It shows a tendency to develop second growth, and under rainy and hot weather is subject to internal brown spot. The tubers of Eigenheimer are deep-eyed, and a large percentage of the crop consists of average and small-sized tubers. Trie marketing value of the Eigenheimer potato equals that...

Five potatoes fertilizers trials were carried out. in diffeient soil types of the State of São Paulo with the purpose to study the effect of nitrogen, phosphoric acid and potash, on tuber production. It was found that nitrogen increased plant growth, intensified green color of foliage and retarded maturity. Nitrogen also increased susceptibility to fungus diseases. Phosphoric acid increased yield and shortened the vegetative period. Potassium induced a light -green color of the foliage, but otherwise had almost no influence on plant development. Phosphoric acid was the most important factor in increasing tuber production : nitrogen was second and potassium, third. A response to potassium was noticed only when this element was applied together with...
