Horsfieldii Miq.. I was able to examine authentic herbarium 
material of the latter species in ’s-Rijks Herbaria at Leiden and at 
Utrecht. 
As a result of this identity, and following the rules for nomen¬ 
clature of the Vienna botanical congress, the name B. Horsfieldii 
of Miquel cannot be maintained and must give way to Bennettia 
leprosipes (Clos.) Koord., nomen nov. 
The above-mentioned fragment of an authentic specimen of Xy- 
losma leprosipes Clos. was presented to me some years ago 
at my request by Prof. Bois of the Museum d’ Histoire Naturelle, 
together with a fragment of the authentic specimen of Xylosma 
fragrans Clos. 
It was only recently, however, that I discovered that Xylosma 
leprosipes Clos. has been erroneously regarded in the literature 
as a species of the genus Xylosma G. Forst, and must be trans¬ 
ferred from this genus to the genus Bennettia Miquel, described 
by Miquel l.c. in 1859; at the same time I found the only javanese 
species of this genus to be quite identical with Xylosma lepro¬ 
sipes Clos. 
Xylosma fragrans Decaisne is however, according to the 
authentic specimen, very sharply marked off from X. leprosipes Clos, 
and has been correctly placed by Decaisne in the genus Xylosma 
G. Forst, which is synonymous with Myroxylon J. & G. Forst. 
The latter species (X. fragrans) was, according to the above- 
mentioned material, collected in Timor. This locality, which was 
written on the label of the fragment in Prof. Bois’ autograph, agrees 
well with the specimens of Xylosma fragrans Decaisne which 
I found in ’s Rijks Herbarium of Leiden. There this species is only 
represented by specimens from Timor. These were collected in that 
island by Spanoghe, Decaisne, Brown and Zippelius. 
In the literature and in ’s Rijks Herbarium X. fragrans is 
therefore only known from Timor, and hence not yet from Java, 
for instance. I found however in ’s Rijks Herbarium a duplicate of 
a sterile undetermined specimen of a very rare species of tree, col¬ 
lected by me in Java (Kds n. 10019 ft from Herb. Buitenzorg), which 
closely resembled some of the Timor specimens. The sterile Javanese 
specimen (Kds n. 10019 ft) is, however, distinguished by the following 
characteristics: foliis juniorifcus laxe sericeis, glabrescentibus; inno- 
vationibus dense sericeis. 
Since the flowers and fruits of this javanese tree are still wanting 
and the original specimen of the Buitenzorg Herbarium is not at my 
disposal now, it does not seem desirable to decide the question whether
