In Africa tropicali :'v.s. in herb. Hook., ^ , Gaboon River 
(Mann, 986) ; Congo (C. Smith). 
This is a plant with slender climbing branches J line thick, 
with internodes 2^-3^ inches long ; leaves inches long, 
with a basal sinus 1-2 lines deep, 1^-2 inches broad, on a petiole 
6-8 lines long ; the two one-flowered pedicels in each axil are 
very slender, nearly erect, 9 lines long ; the flower is 3 lines 
long, line in diameter; the proportions of its floral parts are 
as stated in the generic diagnosis. 
57. Penianthus. 
Among the plants arranged under Fibraurea in the Hookerian 
herbarium, I noticed one from the island of Fernando Po, which 
is very different in habit, particularly in its leaves, which are 
not triplinerved as in that genus; its inflorescence, instead of 
being a very long and laxly spreading panicle, is barely half an 
inch long, consisting of a very short supra-axillary peduncle 
that supports a number of umbellated 1-flowered pedicels of 
half its length, all being pubescent. It is a female specimen, 
its flowers having nine sepals in three series diminishing in size 
outwards and imbricated in aestivation, six minute petals affixed 
by their claws to the feet of as many sterile stamens seated 
round a raised gynaecium which supports three short, gibbously 
cylindrical, pilose ovaries, almost concealed (when seen from 
above) by their very large sessile stigmata, which resemble those 
of Cahjcocarpuin. Its leaves are of considerable size, lanceolately 
oblong, narrowing towards both extremities, and acuminated 
at the summit, having many parallel divergent neiwes that 
archingly anastomose together near the margin, in which respect 
they offer some resemblance to Pycnarrhena. I know of no 
genus to which this plant can be referred.
