Nearly related to and usually confused with T. cordifolia, Yahl, from which, 

 howevei', it is readily distinguished in being dicEcious, in having no slinging hairs,, 

 and in having cymulose male flowers. The dioecious habit it shares, among members 

 of tlie same natural group, with T. Descampsii, De Wild., from Katanga, T. bongo- 

 lana, Prain, from Bongo and Mittu, and T. Balfotirii, Prain {T. dioica, lialf. f. 

 in Proc. Roy. Soc. Edin. xii. 95, not of Sond.), from Socotra. Schimper 661 in 

 Herb. Delessert belongs to T. 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, 2-2 J in. 

 long, IJ-lf ill. wide, sparingly hispid on the nerves on both surfaces 

 and with a few stinging bristles especially near the base on the upper 

 surface ; petiole | in. long, retrorsely hispid ; stipules lanceolate, reflexed, 

 with hispid margins, IJ lin. long. Racemes terminal on stems and 

 branches, 1-sexual, dioecious, only male plants seen, up to 4 in. long, 

 rather dense, with a slender naked retrorsely hispid peduncle \-\ in. 

 long ; pedicels in 8-flowered glomerules, shorter than their bracts ; 

 bracts ovate-lanceolate with hispid margins, reflexed, 1 lin. long. ]\Iale 

 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., witli which it 

 agrees in being dioecious, 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. Jahrh. 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 

 narrow-cordate, margin distinctly and sharply serrate, 2-4 in. long, 

 lJ-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 |-2^ in. long, 

 densely pubescent and sparingly bristly ; stipules lanceolate, 1-1 J Ihj. 

 long, reflexed, densely pubescent externally, glabrous within. Raceme :i.
