Nearly related to and usually confused with 7. cordifolia, Vahl, from which, 
however, it is readily distinguished in being diecious, in baving no stinging hairs, 
and in having cymulose male flowers. The dicecious habit it shares, among members 
of the same natural group, with 7. Descampsii, De Wild., from Katanga, 7’. bongo- 
lana, Prain, from Bongo and Mittu, and 7. Balfourti, Prain (7’. dioica, Balt. f- 
in Proc. Roy. Soc. Edin. xii. 95, not of Sond.), from Socotra. Schimper 661 in 
Herb. Delessert belongs to Z. mitis, in other collections this number accompanies 
T, cordifolia. 
19. T. bongolana, Prain in Kew Bulletin, 1912, 236. Stems 
rather long, slender, twining, sparingly retrorsely hispid but without 
stinging hairs. Leaves distinctly petioled, firm, triangular-ovate, acute, 
base rather deeply cordate, margin distinctly sharply serrate, 2-23 in. 
long, 14-1 in. wide, sparingly hispid on the nerves on both surtaces 
and with a few stinging bristles especially near the base on the upper 
surface ; petiole 2 in. long, retrorsely hispid ; stipules lanceolate, reflexed, 
with hispid margins, 14 lin. long. Racemes terminal on stems and 
branches, 1-sexual, diwcious, only male plants seen, up to 4 in. long, 
tather dense, with a slender naked retrorsely hispid peduncle j-1 in. 
long ; pedicels in 3-flowered glomerules, shorter than their bracts ; 
bracts ovate-lanceolate with hispid margins, reflexed, 1 lin. long. Male 
Sepals 3, wide-ovate, obtuse, rather firm, glabrous. Stamens 3 ; filaments 
rather longer than their anthers.

A very distinct species, most nearly allied to T. mitis, Hochst., with which it 
agrees in being dicecious, but from which it differs in having male flowers more 
than twice as large, with much shorter pedicels and with longer filaments. The 
Sepals are also much thicker and firmer. 
20. T. brevipes, Pax in Engl. Jahrb. xix. 103. Stems usually 
long, slender and twining, sometimes shorter and suberect, densely or 
Sparingly pubescent and sparingly armed with stinging hairs. Leaves 
distinctly petioled, membranous, ovate, acute or acuminate, base deeply 
arrow-cordate, margin distinctly and sharply serrate, 2-4 in. long, 
1}~2 in. wide, sparingly softly pubescent above, densely pubescent, 
Sometimes almost velvety beneath and sparingly beset on both surfaces 
especially on the nerves with stinging bristles ; petiole 3-24 in. long, 
densely pubescent and sparingly bristly ; stipules lanceolate, 1-13 lin. 
long, refiexed, densely pubescent externally, glabrous within. Racemes
