The typical specimen shows this to be a true Forsteronia. It is a shrub with flexuose, 
slender, scandent, glabrous branches; its opposite leaves are oval or oblong-ovoid, 
obtuse at the base, gradually acute and obtusely mucronate at the apex, the margins 
subrevolute, subcoriaceous, glabrous, deep green above, subnitid, sulcate along the 
midrib, with about 12 pairs of patently diverging nerves, with others shorter and inter- 
mediate, all semiimmersed, yellowish and opake beneath, with a prominent reddish 
midrib and scarcely prominulent fine nerves, 23-3 in. long, 1-13 in. broad, on petioles 
2-3 lines long; panicles axillary and terminal, shorter than the leaves, much divided, 
their branchlets 3 lines long, bearing numerous very small white flowers on slender pedicels 
2 lines long; sepals ovate-acute, 4 line long; corolla 3 lines long, externally pruinose ; 
tube 3 line long, villous inside; segments lanceolate, equilateral, membranaceous, very 
villous inside towards the base, sinistrorsely subconvolute; anthers exserted, connivent, 
villous; disk of 5 oblong glabrous lobes, as long as the pubescent ovaries.

Spruce's plant agrees well with the short description of De Candolle. The branches 
are dichotomous, the branchlets spreading, glabrous, shining black, pander, — "e, 
with axils 1 in. apart ; leaves oblong, subacutely obtuse at the base, gradually acuminate, 
thinly chartaceous, glabrous, pale green above, with fine immersed nerves, paler beneath, 
opake, midrib flat, reddish, with scarcely prominulent nerves, 2 in. long, p lines 
broad, on slender spreading channelled petioles 2 lines long; panicles terminal in the 
young branches, spicately racemose, 2 in. long, on a peduncle bare at its pane zer Mine, 
its approximately divided branches bearing very numerous condensated minule flowers 
on pedicels } line long; sepals ovate, subacute, pale and membranaceous, with small inner 
scales; corolla less than 2 lines long, glabrous outside; tube extremely short, sericeous
