 branched, the axillary branches all leaf^' ascending and^yirgatej, densely 

 clothed with spreading or subreflexed tawny setose hairs. Leaves dis- 

 tinctly petioled, narrowly ovate-lanceolate, acute or acuminate, base 

 slightly subhastate-auriculate or shallow wide-cordate, margin finely 

 serrate throughout, 1^-2 in. long, J-^ in. wide across the base, ^J in. wide 

 at the middle, rather sparingly tawny-pubescent, more densely so along 

 the nerves on both surfaces; petiole \-\ in. long, densely tawny-pubes- 

 cent ; stipules lanceolate, erect, 1 lin. long, sparingly setose. Racemes 

 androgynous or at times 1 -sexual, terminal on the stem but not on 

 the leafy branches and leaf-opposed below, slender, very lax-flowered, 

 6-10 in. long; bracts from the middle downwards \-\^ in. apart, 

 gradually more remote, with a short naked densely pubescent basal 

 peduncle J in. long ; flowers all male or with a solitary basal female ; 

 pedicels in both sexes pilose, shorter than their bracts ; uppermost male 

 flowers solitary and 2-bracteolate, lower still solitary but 4-bracteolate, 

 then geminate or the lowest in 2-3-flowered cymules with 4-(i brac- 

 teoles on common peduncles J-l lin. long; bracts subulate, spreading, 

 1-H lin. long; bracteoles narrower, nearly as long as the bracts, all 

 sparingly pilose. Male sepals usually 3, occasionally 4-5, ovate-triangu- 

 lar, pilose externally. Stamens usually 3, less often 2, rarely 4-5, in some 

 cases replaced by solitary imperfect capsules in the flowers of the lowest 

 cymules ; filamentiS as long as the anthers. Female calyx-segments 6, 

 ovate-triangular, pilose, margin entire or subentire, membranous, hardly 

 accrescent. Ovary hispid ; styles 3, short, connate at the base. Capsule 

 3-coccous, sparingly hispid; cocci subglobose. Seeds "reniform" (Beille.)

A very distinct species, not readily comparable with any other known African 

 one. The seeds, which are described by the author as *' reniform," we have not seen. 



3. T. polygonoides, Pram in Kew B^dletin, 11)12, 11)3. Stems 

 long, slender, twining, without stinging hairs. Leaves distinctly 

 to long petioled, membranous, ovate-oblong to ovate-lanceolate, narrowed 

 to a rounded mucronulate apex, base distinctly cordate, margin sub- 

 entire, 21-4 in. long, J-1 J in. wide, with a few adpressed hairs on the 

 nerves above and very sparingly pubescent on the nerves beneath,
