Tree, hemi-epiphytic, up to 20 m tall. Leafy
twigs 3-9 mm thick, glabrous or puberulous, often
also with distinctly longer straight stiff hairs.
Lamina coriaceous, ovate to subovate (or elliptic
to obovate), 7-32 x 2-16 cm, apex shortly acu-
minate to acute (to obtuse), base obtuse to round-
ed or acute to truncate, margin entire or sub-
crenate; upper surface glabrous, lower surface
glabrous or with the main veins having appressed
straight hairs of different lengths, often initially
also with sparse or sometimes rather dense white
arachnoid hairs on the main veins and along the
margin; lateral veins 7-21 pairs, almost straight
to curved, basal pair unbranched or in large leaves
poorly branched, reaching the margin far below
the middle of the lamina; intercostal venation
almost plane to slightly prominent; petiole 2-9
cm long, glabrous or with appressed hairs of dif-
ferent lengths; stipules 1-4 (in rapidly growing
shoots up to 13) cm long, subsericeous (to sub-
hirsute). Staminate inflorescences repeatedly
branched; heads numerous, globose, ca. 1(-2) mm
diam.; common peduncle 1.5-3 cm long puberu-
lous to hirtellous, occasionally also with sparse
arachnoid hairs; perianth 0.5-1 mm high, gla-
brous; stamen one, just exceeding the perianth.
Pistillate inflorescences branched or sometimes
unbranched; heads 1-5, subglobose, 5-8 mm, in
fruit up to 15 mm diam.; (common) peduncle 2-
6 cm long, puberulous to hirtellous; perianth ca.
1-2 mm high, glabrous; fruiting perianth brown-
ish. Interfloral bracts absent.
Distribution (Fig. 8). Upper Amazon Basin
(Bolivia, Peru, Brazil and Ecuador); in upland
and riverine forest, up to 900 m.

Coussapoa ovalifolia is closely related to C.
napoensis. The collection Gentry & Mori 14011,
Panama, Cerro Tacaruna, premontane wet for-
est, 1300 m, 30 Jan 1975 (MO, U), probably
represents a separate taxon, possibly distinct at
the subspecific level from the Amazonian rep-
resentatives of C. ovalifolia. The collection is
similar in most characters to the other collections
of C. ovalifolia, but is distinct mainly in the short
(1-1.5 cm long) peduncle of the pistillate inflo-
rescence andthe branching of the basal lateral
veins-features which hardly justify recognition
as a distinct species. Staminate material is need-
ed to confirm the present supposition.
