Description: Korthalsella Dacrydii (RIDLEY) DANSER, the only species of its genus that is parasitic on Conifers, was, up to the present, only known from two mountains, viz., Mt. Tahan in the Malay Peninsula, and Mt. Gede in Java. For the latter mountain it was, for the first time, not discovered in the living state, but, by Dr VAN STEENIS, on herbarium specimens of Podocarpus imbricata, collected by KOORDERS and VAN DER HOEVEN in 1890. Later it was collected several times on Mt. Gede in the living state.\nWhile examining the materials of Podocarpus and Dacrydium of the Leiden, Buitenzorg, and Groningen Herbaria, I was so fortunate as to discover, in the same way as Dr VAN STEENIS did, several new localities of Korthalsella Dacrydii, and these not only in Java, but also in Sumatra, Borneo, and Timor. The localities now known are the following.

Description: In 1938, Verdam published an account of the then-known Charophyta of the Netherlands in the English language (cf. this journal, vol. 3), and one year later (1939) another in our own language in \xe2\x80\x9cNederlandsch Kruidkundig Archief\xe2\x80\x9d. In both papers reference was made to only five Netherlands\xe2\x80\x99 publications on the same subject, the oldest of which is dating from 1846. In studying i.a. the history of the Malaysian Charophyta (Zaneveld, 1940) I found that much more was published on the Charophyta of our Low Countries. As will be seen below, it became evident that the first printed record of a Netherlands\xe2\x80\x99 Charophyte dates as far back as 1636. It seems worth while to publish these notes on the history of the identification of our Charophyta as, moreover, a number of additional facts have become known.\nThe data of the present review have been taken from the following sources (chronologically arranged): 1. herbals ; 2. catalogues of Botanic Gardens; 3. local floras; 4. general floras and taxonomic textbooks; 5. monographs.

Description: The Talaud Islands are forming part of the Malay Archipelago, being situated north of Celebes and the Moluccas, south of Mindanao and east of the Sangihe group, between 3\xc2\xb045\xe2\x80\x99 and 5\xc2\xb035\xe2\x80\x99 N. lat. and 126\xc2\xb032\xe2\x80\x99 and 127\xc2\xb010\xe2\x80\x99 E. long.\nThe main group consists of three larger islands, viz. Karakelong, Salebaboe and Kaboeroeang. The Nenoesa islands, a group formed by the small islands of Garete, Karaton, Merampi, Mengkopoe, Intata, Kakelotan and Maroh are situated northeast of the main group, including also Miangas (Palmas), an islet about 65 miles north of Karakelong, near Mindanao.

Description: More than two years ago I published, in collaboration with W. W. VAROSSIEAU, a Revision of the Sarcospermataceae (Blumea 3, no. 1, 1938, 183\xe2\x80\x94200), to which a small map was added, showing the areas of the 6 species known. Four of these have more or less continuous areas on the Continent of Asia, one is only known from a small area on Sumatra\xe2\x80\x99s East Coast and one, taxonomically speaking the most isolated species, has a remarkably discontinuous area, the parts of which are widely spread over Malaysia. As was already mentioned in an additional note (Blumea 3, no. 2, 1939, 262), this species, Sarcosperma paniculatum, has also been collected in South-Celebes. Recently I came upon a specimen from New Guinea, collected by CLEMENS: 2. S. paniculata (KING) STAFF & KING. New Guinea: N.E. New Guinea, Morobe Dist., Sattelberg, 3300\xe2\x80\x99 alt.: CLEMENS 1292, flow. on 20. 12. 1935. The small localities in which this species has been found are now known to be scattered over: the Malay Peninsula (Perak), Sumatra (East Coast opposite Perak), Borneo (Mt. Kinabalu), Mindanao (Mt. Apo), South-Celebes, Flores, Ternate, N.E. New Guinea (Sattelberg). The New Guinea specimen shows medium-sized inflorescences. I take this opportunity to quote some more specimens, examined by me in the collections of the British Museum, Natural History, during a short visit in May 1938: 3. S. arboreum HOOK. f. INDIA, Assam, Garo Hills, Tura, 4000\xe2\x80\x99 alt.: C. B. CLARKE 43080 B, flow. 011 14.2.1886; Khasia, Nongpriang, 1000\xe2\x80\x99 alt.: ID. 15022, buds on 21.11.1871. 6. S. Griffithii HOOK. f. INDIA, Assam, Khasia, Mausmai, 3500\xe2\x80\x99 alt.: C. B. CLARKE 43719 B, fr. on 9.5.1886; ibid., sine loc.: KING\xe2\x80\x99S Coll. sine num.

Description: Eighteen species of plants, most of which were chosen at random, were sown beside a hedge of Artemisia Absinthium; they were severely injured and in one ease ( Levisticum officinale) even killed by the chemical excretions of the latter within a distance of \xc2\xb1 100 cm; seedlings of Artemisia Absinthium, on the contrary, were not harmed by the plants in the hedge. The experiments were made during two successive summers and in different surroundings; the results were consistent and confirmed those of Bode, notwithstanding the fact that climatic conditions were extremely unfavourable for the excretion of absinthiin and that even during fine weather it appeared to be feeble owing to the sea climate of Leiden. Spells of cold and of heavy rains sometimes kept the excretion so low that temporarily the absinth plants seemed to exert no action at all.\nSeedlings which had survived the proximity of the absinth in their first year developed normally during the next season. It was demonstrated that the proximity of Atriplex hortensis had no influence on the same test plants which were injured by Artemisia Absinthium and that they were only physically oppressed by Artemisia vulgaris, viz. by its spreading, branches. This makes it probable that it is indeed the absinthiin, excreted by Artemisia Absinthium, which causes this species to be harmful to the surrounding plants.\nFresh leaves of Artemisia Absinthium, dug in the soil, reduced the percentage of germination and sometimes also hindered the development of the seedlings of a number of species. Foliage of Artemisia vulgaris had sometimes a similar action, but seldom to the same degree. In the case of A. Absinthium two harmful effects are apparently combined: a too great amount of organic manure and the formation of absinthiin.\nIt will be worth while to examine the ecological importance of Artemisia Absinthium in its natural habitat.

Description: Anne Antoinette van Bosse, fille de M. Jacob van Bosse et de Mme Jaqueline Jeanne n\xc3\xa9e Reynvaan, naquit \xc3\xa0 Amsterdam le 27 mars 1852. Tr\xc3\xa8s jeune encore elle perdit sa m\xc3\xa8re; sa soeur, son ain\xc3\xa9e de 10 ans, prit sa place aussi bien qu\xe2\x80\x99elle put. Outre cette soeur elle avait trois fr\xc3\xa8res.\nSelon l\xe2\x80\x99usage de cette \xc3\xa9poque les familles ais\xc3\xa9es n\xe2\x80\x99envoyaient pas leurs filles \xc3\xa0 l\xe2\x80\x99\xc3\xa9cole, ainsi Anna van Bosse re\xc3\xa7ut \xc3\xa0 la maison son instruction par une institutrice de nationalit\xc3\xa9 suisse. La botanique et la zoologie furent d\xe2\x80\x99embl\xc3\xa9e ses branches pr\xc3\xa9f\xc3\xa9r\xc3\xa9es; les fr\xc3\xa9quentes visites au jardin zoologique \xe2\x80\x9dArtis\xe2\x80\x9c y contribu\xc3\xa8rent pour une grande part. l\xe2\x80\x99Observation des animaux exotiques lui procurait un grand plaisir et jusqu\xe2\x80\x99\xc3\xa0 pr\xc3\xa9sent elle porte un grand int\xc3\xaaret \xc3\xa0 \xe2\x80\x9dArtis\xe2\x80\x9c.

Description: In Eerbeek, in einem der sch\xc3\xb6n gelegenen D\xc3\xb6rfer der Provinz Gelderland, steht ein altes Schloss, von der Verkehrsstrasse weit entfernt, und am Bach entlang zu erreichen. Es ist das sogenannte \xe2\x80\x9dHuis Eerbeek\xe2\x80\x9c, das Haus der Frau Dr. Weber, die Herrin im wahren Sinne des Wortes.\nDa k\xc3\xb6nnen wir heute der neunzigj\xc3\xa4hrigen begegnen, beim Heruntersteigen der steinernen Treppe, oder auch am Teiche, bei den Karpfen und Enten; nicht selten auch trifft man sie ihre sch\xc3\xb6nen Buchenalleen musternd, durch die sie mit raschen Schritten sich fortbewegt. T\xc3\xa4glich nach dem Mittagsmahl geht sie spazieren, manchmal um mit dem G\xc3\xa4rtner und mit ihren Bauern etwas zu besprechen. Und was gibt es in der heutigen Zeit nicht alles auf einem Gut zu tun, das Gut, das sie mit ihrem Gatten geh\xc3\xbctet und entwickelt hat, bei welcher Arbeit sie beide ihren grossen biologischen Interessen fr\xc3\xb6nen konnten.

Description: It needs an explanation why among the botanical papers published in this volume to honour Mrs. Weber\xe2\x80\x94van Bosse on her 90th birthday a zoological contribution has been inserted. Those who have read the curriculum vitae of this wellknown botanist in the foregoing pages of this volume will not wonder, for they know that she has been keenly interested for more than half a century in the zoological work of her late husband. And so among the chorus of botanists the voice of a zoologist could hardly be missed. For many years I have enjoyed the friendship of both, and I am grateful for this opportunity to show Mrs. Weber my affection and my admiration.\nWhen contemplating an adequate theme for this paper it occurred to me that in some way or other it had to dwell on the relations between zoology and botany and as the distribution of animals is a branch of science which has always interested both Max Weber and me, I decided on the influence which the distribution of plants has on that of animals.
