Trees
to
10 m
tall; young branches terete, tenuous, bark green, densely pannose with brownish hairs
0.12–0.50 mm
long, adult shoots darkly grey, sub-glabrous; buds densely pannose.
Leaves
dimorphic, small ones nearly opposite to large ones, internodes between similar
types
of leaves
1.3–3.5 cm
, between two adjacent different
types
of leaves
1–3 mm
;
small leaves
caducous, sessile, lanceolate,
8–12 mm
long,
2–5 mm
wide, base obtuse, apex acuminate, sparsely pannose on both surfaces, main veins 5, obscure adaxially and slightly prominent abaxially;
large leaves
petiolate, petiole
3–5 mm
long, 1.0–
1.2 mm
in diam., pannose with brownish hairs or glabrous; leaf blade elliptic to broadly ovate,
9.5–12.5 cm
long,
3–5 cm
wide, base slightly oblique, acute to obtuse, apex narrowly acuminate, thinly coriaceous, sub-lustrous adaxially, sparsely pannose on both surfaces with indumentum denser along main veins when young, glabrescent when mature; main longitudinal veins 5, springing from blade base, two inner lateral veins merged with midrib above blade base at
1.5–4.5 mm
in one side and
4–9 mm
in another side respectively before separated, outermost two veins very fine, only
1–2 mm
from blade margins at base and upward almost confluent with blade margins, impressed adaxially and raised abaxially; transverse veins parallel, at angles of 50–65° with midrib, obscure adaxially but distinctly prominent abaxially; veinlets reticulate.
Inflorescence
an axillary spike, rachis ascending, tenuous, to
9 cm
long,
0.5 mm
in diam., moderately tomentose or sparsely manicate with brownish tortuous hairs to
0.2 mm
long, densely with flowers; bracts narrowly lanceolate, to
2 mm
long,
0.25 mm
wide, with widest point at middle, apex acute, glabrous adaxially, pannose abaxially; flower buds subglobose, to
1.5 mm
long,
1 mm
in diam., sparsely pannose with hairs denser at base;
flowers
bisexual(?), 4- merous, sessile; sepals broadly ovate, apex broadly acute, margins shortly ciliate, densely pubescent with short hairs abaxially; petals ovate, base entire, broad, irregularly 5 laciniate from middle or rarely lower, laciniae glabrous on both surfaces; stamens 8, free, inserted inside thick disk, filaments tenuous, base dilated, anthers small,

sub-globose; styles 4, free, elongated, base clavately dilated, distally attenuate, sub-pubescent, stigma shortly thickened.
Fruit
a drupe, obovoid, ca.
3 cm
long,
1.5 cm
in diam., attenuate towards both ends, glabrous.

Anisophyllea strychnoides
Engler & von Brehmer. Leafy
branch (
G. F. Scott-Elliot 4154
; lectotype, K-000075945).
Flowering and fruiting:
—Flowering in December and fruiting time unknown.
Habitat and distribution:
—In bushland; below
1100 m
.
Guinea
(Faranah);
Sierra Leone
(

).
Taxonomic notes:
—
Anisophyllea strychnoides
is similar to
A. obtusifolia
but can be distinguished from the latter by its sepals densely with short hairs on abaxial surface, its inflorescences without long hairs (up to
1 mm
long) and its bracts much shorter (ca.
2 mm
long vs. to
3.5 mm
long in
A. obtusifolia
) (
Engler & von Brehmer 1917
,
Engler 1921
). It is also close to
A. laurina
,
to which it had been considered conspecific (Hutchison & Dalziel 1954), but it differs from the latter by the transverse veins forming relatively smaller angles with the midrib, its

young branches without concurring pubescence of hairs to
0.8 mm
long, and other much subtle morphological differences. However, the circumscriptions of these species need more investigations.
There were three collections (
syntypes
) cited in the protologue but we only found two of them. Here we designate one duplicate of
Scott-Elliot 4154
deposited at
K
as the
lectotype
.
The
identity of
Henriques

from
Bolama
in the
Senegambisch-Westsudanische Zone
, which would be in
Guinea-Bissau
, is uncertain and the distribution of this species there is not listed here
