Oliv.
Trees, or more rarely, scandent shrub or liana. Leaves (4-)5-10(-13)-jugate; leaflets papery to coriaceous, the lowest pair sometimes close to the stem, (2-)10-25(-36) × (1-)4-7(-12) cm, with 10- 16 pairs of main lateral nerves, ± glabrous above except for the usually pubescent, impressed midrib, ± glabrous to sparsely appressed-puberulous to pubescent beneath, usually minutely pustulate above. Inflorescence brown-velutinous, (sub)terminal or borne below the leaves. Flowers (Jan.-Dec.) with white to pinkish petals. Fruits (June-Feb.) pink to dark red, subellipsoid, up to 3 ×

NOTES
. —
In Upper
Guinea
Trichoscypha lucens
has always been reported as a shrub or small tree, the
lectotype
from outside this area, collected by
Mann
, being the only exception (
BRETELER 2001: 261
).
Although
the material from
Lower
Guinea
and Congolia has a similar habit, a few collectors have described plants as lianas or lianescent shrubs, e.g.,
Leeuwenberg 5335
from
Cameroun
,
Devred 1980
and
2076
from
Congo
(Kinshasa), and
Lewalle 6124
from
Burundi
.
The
neotypes
chosen for three synonyms,
T.coriacea
,
T. ledermannii
, and
T. pallidiflora
, have, as far as possible, been selected according to the origin of the type material (which appears to have been lost at Berlin) and the original description.
Of the 12 new species described for the
Flore du
Congo Belge
et du
Ruanda-Urundi
by
VAN DER VEKEN (1959
,
1966
), seven are treated here as synonyms of
T. lucens
, one of the very variable species of
Trichoscypha
and the most wide spread.
VAN DER VEKEN (1960)
distinguished these seven species both by habit and leaflet characteristics, such as shape, size, texture, and details of the acumen. These elements have proven to be of little or no value for specific segregation.
