Shrub or small tree up to 15 m tall, trunk to 20 cm in diam. Leaves (2-)3-6(-7)-jugate; leaflets papery to coriaceous, lanceolate to narrowly elliptic, 2.5-4(-4.5) times as long as wide, (6-)8- 17(-27) × 2.5-5(-7) cm, shortly cuneate to rounded at base, gradually acuminate, lateral nerves often rather indistinct, c. 8-12 pairs; midrib impressed above, glabrous or nearly so. Inflorescence (sub)terminal, more rarely borne below the leaves. Flowers (Sep.-Dec.) usually pedicellate, the female ones distinctly so, white, fragrant. Fruits (Jan.-Mar.) glabrous or nearly so. — Figs. 1 M-N, 10.

NOTES. — KEAY (1958) included in T. smythei Linder 1329 , the type of the new species T. linderi . In his key to the species he used a character of this specimen, viz. that the inflorescence is born below the leaves. This feature, however, is not shown by the type (Unwin & Smythe 33), nor is it mentioned by HUTCHINSON & DALZIEL, the authors of T. smythei . KEAY in fact misinterpreted the identity of this specimen and as a consequence proposed T. smeathmannii as a new name for Brucea paniculata Lam. , for which T. smythei was in fact available, and did not recognize that Linder 1329 represented a new species.

Trichoscypha linderi is very different from T. smythei , not only by its cauliflorous habit, which occasionally occurs in the latter as well, but especially by its very different leaves and larger male flowers with a cupular disc.

Trichoscypha smythei is very closely related to T. lucens . I have refrained from uniting them in particular for the lack of fruiting specimens. The disc and the ovary vary from completely glabrous or with a few sparse hairs, as represented by T. smythei , to densely velutinous as in T. lucens . The scarce available fruiting material can be classified in the same way, i.e. with glabrous or nearly glabrous fruits in T. smythei and with densely velutinous fruits in T. lucens . More fruiting material, especially from Côte d’Ivoire, is needed to decide whether T. smythei can be maintained as a distinct species.
