Closely allied to T, rupestriSj Sond. , and treated by Sonder and Slllller as only 

 varietally distinct from that species, but easily recognised by it^j almost glabrous 

 leaves with much shorter petioles and by its smaller fruits. The leaves in T. 

 wahlbergiana are not auriculate- cordate as is usually the case with T. rupestris. 

 More closely allied still to T, durhanensis, 0. Kuntze, but distinguishable by its 

 more deeply lobulate female calyx -segments. 



12, T. durhanensis (0. Kuntze, Rev. Gen. PL iii. ii. 293); a herb 



with woody base ; stems slender, twining, sparingly branched, 

 4-8 ft, long, usually glabrous, sometimes sparingly armed with 

 stinging bristles ; leaves lung-petioled, membranous, triangular-ovate, 

 acute, base rather deeply widely to narrowly cordate, margin closely 

 strongly toothed, 1^-3 in. long, 14— 2^ in. wide, glabrous or nearly 

 so above, beneath usually very sparingly beset with stinging bristles 

 on the nerves ; petiole sparingly bristly or glabrous, |-1 lin, long : 

 stipules spreading, lanceolate or ovate lanceolate, glabrous, 1^-2 lin. 

 lung ; racemes terminal on the branches or leaf-opposed on the stem, 

 with many male flowers solitary to their bracts above and 1-2 basal 

 female flowers ; peduncle and rhachis finely puberulous with some- 

 times a few long bristles ; male bracts ovate-lanceolate, entire, 

 glabrous or nearly so, 1 lin. long ; female bracts ovate-lanceolate, 

 entire, glabrous, 2 lin. long ; male calyx 3-partite ; lobes ovate, acute, 

 glabrous ; stamens 3 ; filaments longer than the anthers, incurved ; 

 female calyx 3-partite ; lubes suborbicular, palmately 5-6-lobulate 

 on each side, pubescent externally, glabrous within ; lobules much 

 shorter than the width of the accrescent indurated rhachis, in fruit 

 ^ in. long ; ovary puberulous and setose; styles 3, connate below iii 

 a short column, free above ; capsule 3-coccous, ^ in. across ; cocci 

 almost glabrous, subglobose ; seeds globose. T. capensisy E. Meyer
