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

1 began my investigations about the galls of the Loranthaceae in Salatiga in 1908 and continued this work in Samarang from 1909 to 1915. Here I also examined the germination of the seeds. From 1915—1918 I stayed in Bandung where I had little opportunity to continue my investigations. From 1918—1932 I lived in Buitenzorg (Bogor) where I could resume my studies on the Loranthaceae, not only as to the germination of the seeds, but also the pollination of the flowers. For this purpose I sowed many species of Loranthaceae on shrubs in the neighbourhood of my home, so that I could easily check the development and had ample material at my disposal. The investigations were hampered by the chaotic conditions of the systematics of the Indomalayan Loranthaceae in...

Trientalis europaea L

In 1935 zocht ik naar gallen in de omgeving van Denekamp. Ik zag een boer, die een houtwalletje, dicht begroeid met Zevenster aan het omspitten was. Twee exemplaren nam ik met een goede kluit mede naar Leersum. Zij werden in onze tuin uitgeplant. Die tuin was oorspronkelijk ongeveer 60 Jaar oud dennebos, tegen de tamelijk steile helling van de Utrechtse heuvelrug. Door het hoogste gedeelte loopt een berkelaantje en de begroeiing van het terrein bestaat behalve uit dennen uit eikjes, lijsterbes, sporkenhout en Prunus serotina. De bodem is dicht bedekt met Bochtige Smele.

Botanical results of a trip to the Salajar Islands

The Salajar Islands strew the Flores Sea between Celebes and Flores. The group consists of no less than 73 smaller and larger islands. The principal islands are: Salajar or Tanadoang, Djampea, Kalao, Kalaotoa, and Bonerate. A number of smaller islands form together the group of the so-called Tiger Islands, and to the south of them arc the very small, low Pasitaloe Islands. The Salajar group is situated between Long. 119°50’ E. and 121°30’ E. and between Lat. 5°36’ S. and 7°25’ S. See the map on p. 240. In May 1913, I was enabled to visit this territory, thanks to a financial allowance of the „Maatschappij ter bevordering van het Natuurkundig Onderzoek der Nederlandsche Kolonien” (Society for the Promotion of the Scientific Investigation of the Netherlands...

The biology of Epipogium roseum (D. Don) Lindl

Ano: 1937

URL: http://www.repository.naturalis.nl/record/525123

Epipogium roseum is a tropical, holosaprophytic orchid; it lacks chlorophyll, and its colour on the whole is pale yellow, occasionally somewhat brown. The flowers are also pale yellow, sometimes with pink dots on the lip. The flowering plant consists of a tuber and an inflorescence, roots are lacking. When the flowering is over and the fruits have dehisced, the plant dies. It grows in densely shaded places, rich in humus, in virgin forests, secondary woods, and in bamboo wildernesses. The plant is of frequent occurrence in the so-called forest-garden in the Botanic Gardens at Buitenzorg and in the lower parts of the mountain forest near Tjibodas, up to an altitude of about 1500 m above sea-level. For many years this plant has held my attention. Burgeff...

Some galls from the island of Enggano

Ano: 1937

URL: http://www.repository.naturalis.nl/record/526298

The island of Enggano is the most southern of a series of islands situated parallel to the Western coast of Sumatra. In 1936 the island was visited by Dr. W. J. LüTJEHARMS, who stayed there from the end of May to the beginning of July collecting materials for the Herbaria at Buitenzorg and Leiden. During this excursion he also collected some zoocecidia, which were sent to me for classification by the Director of the Rijksherbarium, Leiden. The collection consists of 16 galls on various plants; many of them were already known as occurring in other parts of the Malay Archipelago; others are new, these are marked with an asterisk. A collection of 16 galls is actually to small to give insight into the wealth of galls of this tropical island; so far, however,...

In Blumea, Vol. II, 1937, pp. 239 to 277, appeared an article bearing the above title. It is a description of an excursion to the Salajar Islands, situated south of Celebes; lists of the plants found in the islands are appended. Prof. Dr C. E. B. BREMEKAMP wrote to me that in the Leiden Herbarium a small collection of plants, collected by me in the Salajar Islands, and long ago lent to the late Dr TH. VALETON, have been found. This collection contained, apart from the Rubiaceae, the special subject of Dr VALETON, some representatives of other plant families. Prof. BREMEKAMP sent me a list of names of these plants, for which I tender him my cordial thanks. Besides he communicated to me that a few plants are mentioned under wrong names in the original...
