4. D. (Heterotis) Afzelii, Hook.f. Branches stout, elongate, 

 flexuous (climbing'?), densely villous, more bristly at the nodes with 

 spreading* deflexed stiff and curled hairs. Leaves 2-2J in. by 1-1 \ in., 

 ovate, subacute, 5-nerved, quite entire, 'base rounded or cordate, upper 

 surface sparsely clothed with appressed or spreading" hairs, under sur- 

 face hirsute ; petiole J-^ in. hirsute. Flowers 1-1^ in. in diameter, 

 capitate, shortly pedicelled ; outer bracts leafy, inner broadly ovate, 

 equalling" the calyx, subscarious, ciliate, persistent. Calyx-tube ovoid, 

 J in., covered with simple or pedicelled stellately or palmately ar- 

 ranged bristles ; lobes 5, ovate-lanceolate, half the length of the tube, 

 ciliate, bristly at the tip and back, persistent. Petals large, broadly 

 obovate. Anthers of long stamens J in., equalling the connective, 

 appendage clavate entire. Capsule sunk in the subcampauulate calyx- 

 tube,, which is \ in. long, crown free, 5-valved, bristly at the tip. 



Upper Guinea. Sierra Leone, Afzelius / 



Habit of Tristemma involucratum, but calyx and anthers very different. Afzelius 

 in a ms. note states the stamens to be 5, a point I cannot determine from his imperfect 

 specimens. 



5. D. (Heterotis) theaefolia, Benth. in Fl. Nigr. 351. A small pale 

 shrub. Branches stout, white, obtusely 4-angled, scabrid with minute 

 very distant short bristles ; nodes with few long erect stiff bristles. 

 Leaves subsessile, 1— 2J in. by \-l in., oblong-lanceolate or linear-ob- 

 long, obtuse or subacute, rigidly coriaceous, 3-nerved, equally sparsely 

 6trigillose and green on both surfaces. Heads many-flowered, sessile 

 between the upper pair of leaves, 1-1J in. in diameter in fruit ; outer 

 bracts foliaceous, scabrid ; inner imbricate, very broad, truncate, hard 

 and coriaceous, pale, quite smooth, edges membranous, persistent. 

 Flowers sessile, lj in. in diameter, dull purple. Calyx-tube oblong, 

 J in., smooth, glabrous, terete, base without bristles ; lobes ovate- 

 lanceolate, acute, membranous, half as long as the tube, persistent. 

 Petals broadly obovate. Anthers of long stamens J in., connective 

 nearly as long ; connective of short stamens very short. Capsule 

 membranous, nearly free, 5-valved at the tip, with an apical ring of 

 bristles.

6. D. (Heterotis) capitata, Benth. in Fl. Nigr. 352. A small 

 shrub. Stems robust, erect or weak and flexuous, diffusely branched, 

 branches obtusely 4-angled, more or less scabrid j nodes with 1-2 

 short erect bristles. Leaves 3-5 in. by 1-2 in., ovate, acute, 5-7-nerved, 

 sparsely strigose above, pale and nearly glabrous (with few microscopic 

 hairs) teneath ; petiole \-\ in. Heads few-flowered; outer bracts
