clothes were almost torn asunder, as well as the skin on the hands and 
the face." This description applies unmistakably to a group of palms, 
the rattans, characteristic of the Indo-Malayan region, the " prehen- 
sile " characters of which are well known to all who have traveled in 
the forests of the Malay Archipelago. Among all the Javan species, 
however, Osbeck's description applies best to Ceratolohus glaucescens 
Blume, the only other possible species being Korthalsia rohusta Blume. 
However, Osbeck's specimen was from near sea level in western Java, 
which practically excludes the Korthalsia from consideration in this 
connection. Koorders^ gives the distribution of Ceratolohus as 
" West Java: In den unteren Gebirgsgegenden von den Residenzschaf- 
ten Bantam, Batavia, und Preanger . . .," while, according to the 
same author, the occurrence of Korthalsia rohusta Blume in western 
Java is doubtful. 
It is to be noted that Osbeck describes the leaves of Caryota 
javanica as hipinnate, which is not true of any of the Malayan palms 
that are supplied with hooked spines. The term hipinnate was ap- 
parently used to make the description of Caryota javanica agree with 
the generic description of Caryota, through faulty observation, or 
possibly because the exact significance of the term was not understood 
by the author. It is apparent, however, that Osbeck prepared no 
botanical material of this species, and that he probably wrote up his 
diagnosis, at least in part, from memory.

Osbeck's species is not listed in Index Kewensis, and his specific 
name, although much older than Volkameria commersonii Poir. 
(1808), is invalidated in Clerodendron by C, javanicum Spreng. The 
species is the common coastal form that has been called by most 
botanists Clerodendron inerme (L.) Gaertn., but which Clarke^ and 
Gamble^ have retained as a distinct species under the name Clero- 
dendron neriifolium Wall. (1829) , Osbeck's type was from near Anjer, 
Java, observed by him July 16, 1 751, associated with Acanthus 
ilicifolius L., Convolvulus pes-caprae L., Ischaemum muticum L., 
Vitex trifolia L., and other typical strand plants. The original de-
