A.S in S. Penangianus, I have observed that in many cases 
where the ovarium is oimligerous, the anthers have been charged 
with perfect pollen, so that such flowers may be said to be truly 
hermaphrodite: in most instances, however, the ovarium is ste- 
rile. The leaves are from 3^ to 4i inches long, including a nar- 
row and almost linear apical point of half an inch in length ; they 
are to 1|- inch broad, on a petiole half an inch long; the 
racemes, ^ to f inch long, have numerous crowded flowers which 
do not exceed 3 lines in length : the hairs of the filaments are 
three or four times the length of the anthers, and arch over 
them in a very graceful manner ; the pollen-grains are acutely 
3-gonous.

Tlie leaves here are 5-6i inches long, and 2|-3 inches broad, 
on a petiole 5-7 lines in length ; the panicle is trichotomously 
branched, with crowded 5-merous flowers, which are still in bud ; 
the upper margins of the petals are deeply inflected, together 
with their long apical points, which are all closely agglutinated 
into a long process that hangs down in the centre of the anthers ; 
the filaments are rather short and broad, fringed with extremely 
long glandular hairs ; the ovarium, seated on a short glabrous 
disc, is cylindrical, and altogether very pilose, growing smaller 
and more conical towards the summit, where it is hollow and 
5 -toothed.
