for tliirteen years (until 191 Ij among tlie "Indeterminata", no one 

 having even recognized the natural order. Then, in 1911, when 

 revising my herbarium collections for the Systematisches Verzeichnis 

 of Mrs. KooRDPiifs— ScHUMACHKi!, the twigs came again under my 

 eyes, and misled by an external resemblance to some species of 

 the genus Litsea, and in tlie absence of flowers and fruits, I labelled 

 them doubtfully as an undeterminable species of Litsea. Under 

 this preliminary determination, namely as Litsea? spec. div. the 

 above material (Kds. n. 31118, ï) was first published in the Syste- 

 matisches Verzeichnis (I Abteil ^ 1 Fam. 102, p. 34), with mention 

 of the station and time of collection. 



Recently, on March 25*'', when re-examining this 17 year old 

 herbarium material (Kds. n. 31118 /i) 1 found that, without the least 

 doubt, it was identical with the fruiting twigs collected by me on 

 March 15''' at the same spot, and then at once recognized as 

 Sloanea javanica; these twigs (Kds. n. 42813 /? and 42807 i?) 

 were derived from two of my "numbered" trees (namely ') tree 

 23h and tree 39»). The old herbarium material was also identical 

 with a specimen consisting only of leafy twigs (Kds. n. 42814 ,:?), 

 which bore especially large leaves and had also been collected by 

 me in the jungle of Depok on March Ihtli, from a very young 

 unnumbered tree. 



Geographical distributiou. Whereas Sloanea Sigur may be 

 counted among the commonest forest trees of Western and Central 

 Java, as well as of Eastern Java, growing chiefly at an altitude of 

 600 — 1200 metres, and also occurs far outside Java. e.g. in India, 

 Sloanea javanica, which is sharply differentiated from the 

 former species by its not prickly fruits and entire petals, is so far 

 not known outside Java, and has not been found wild in Java 

 outside tlie forest of Depok. 



>S 1 o a n e a ja v anica is the only species of the subgenus Phoe- 

 nicospermum (Miq.) Schumann, in Engler and Pr anti's 

 Nalürliche Pflanzenfamilien 111 6, (1890) 5. This subgenus was 

 formerly (1865—1866) erroneously published by Mi quel as a 

 new genus, under the name P h o e n i c o s p e r m a.

 sea-level, and consisting principally of evergreen trees with many
