This species is most nearly related to T. Hildehrandtii, ]\Iull. Avg., with wliich 

 it agrees in habit, but from which it differs in having all the leaves distinctly 

 3-partiteand in its much larger female calyx. Except as regards the female cal}x 

 it is hardly distinguishable from T. cannahina, Limi. i'., var. intermedia, and lias 

 indeed been included by Schweinfurth in that species. Variable, however, as that 

 species is, this suggestion is not oiie that it is advisable to adopt. 



14. T. Descampsii, De Wild. Etudes Fl. Katamja, 207. Stems 

 erect from a woody base, about 1 ft. high, sparingly branched, densely 

 pilose with soft retrorse pubescence and sparingly armed with a few 

 stinging hairs. Leaves very shortly petioled, ascending, membranous, 

 ovate, acute, base rather shallowly wide-cordate, not auriculate, margin 

 sharply serrate, all young, the largest seen J in. long, J in. wide, densely 

 velvety and along the nerves rather closely armed with stinging hairs 

 on both surfaces ; petiole densely pubescent and sparingly bristly, 

 1-1 J lin. long ; stipules lanceolate, spreading or reflexed, membranous, 

 1 J lin. long, with setose margins and a few hairs on the outer side. 

 Racemes 1-sexual, dioecious, terminal on the stem and branches and 

 below leaf-opposed ; males up to 4 in. long, with a basal naked softly 

 pilose peduncle J-lJ in. long; flowers very numerous, close-set above, 

 sparse (at times J in. apart) towards the base, ternate throughout or in 

 very shortly peduncled 3-flowered cymules towards the base ; pedicels 

 pilose, shorter than the bracts; bracts linear-lanceolate, IJ lin. long, 

 densely pilose on the margins and externally. Male sepals 3, wide- 

 ovate, acute, densely pubescent and bristly externally. Stamens 3 ; 

 filaments longer than the anthers. 



South Central. Belgian Congo : Katanga, Descamjps ! 



Very closely allied to T. Rhodesi<B, Pax, but readily distinguished by the more 

 densely pubescent leaves, shorter in proportion to their widtii, by the much longer 

 racemes with more definitely and uniformly glomerulate male flowers and by the 

 apparently strictly dioecious habit. The leaves in the only specimen seen are not 

 full-grown and will doubtless prove to be less pubescent in the adult than in the 

 •nvenile state. 



15. T. Rhodesiae, Pax in Engl. Jahrh. xxxix. 665. Stems erect 

 from a woody base, 8 in. to 2 ft. high, sparingly branched, pilose with 

 soft reflexed pubescence and very sparingly armed with a few spreading 

 or ascending stinging hairs. Leaves very shortly petioled, ascending, 

 membranous, ovate-lanceolate, acuminate, base rather deeply wide- 

 cordate, not auriculate, margin sharply serrate, 1 J in. long, § in. wide, 

 sparingly adpressed-pubescent and rather closely beset along the nerves
