 the gland, glabrous, minutely ciliate. Ovary puberulous; periantli

8. S. glaucescens. Pax in Engl, Jahrh. xxxiii. 289. A shrub 

 7-8 ft. high. Flowering branches stout, J-| in. thick, apprirently 

 deshy at the tips, glabrous, not glaucous. Leaves 5-6 in. long, l|-2^ 

 in. broad, oblanceolate or cuneate-obovate, acute and apparently some- 

 what recurved at the apex, tapering from above the middle into a 

 stout petiole J-J in. long, with a wing-like entire keel J-1 lin. broad 

 along the midrib beneath and the margins entire or toothed at the 

 apical part, more or less undulate, not ciliate, glabrous on both sides. 

 Cymes axillary, lax, lJ-4 in. long, including the f-2 in. -long glabrous 

 peduncles, with 3-5 subumbellately arranged or closely placed thinly 

 'pubescent branches, once or twice forked or with 2-3 involucres scattered 

 along them. Involucres sessile, 2-2-| lin. in diam., puberulous outside, 

 with an entire spreading rim-like gland and 5 erect subquadrate trun- 

 cate-toothed lobes, as long as broad, puberulous on the back. Ovary 

 thickly puberulous ; styles |-1 lin. long, united to the middle, bifid at 

 the apex, with slightly thickened stigmas. Capsule about 2|-3 lin. long, 

 smooth, thinly and minutely puberulous (glabrous to the eye), with a 

 rudimentary 3-lobed perianth at its base, exserted from the involucre on 

 a recurved pubescent pedicel. Seeds 1 J lin. long and 1 lin. broad, slightly 

 compressed, oblong-ellipsoid, brown, thickly covered with pale greyish 

 dots.

The branches of the type specimen are not pruinose as originally described, but 

 the epidermis of one piece of stem is attacked by a fungus and has undergone some 

 change in the process of drying, producing a bluish colour; the other two pieces 

 show no evidence of this. I do not find the pedicels to be glabrous or the rimvof 

 the involucre lobed as originally described. Busse 165, from Mkatta Kiver, referred 

 to S. glaucescens by Pax, is a totally different species, with the flowers in simi»If 

 umbels of 3-5 rays, each bearing but one involucre, never forked, and t'le capsules 

 are larger, rugose (not smooth), glabrous, and tl)e seeds different. Possibly it mny 

 belong to S. Volkensii, Pax, but the specimen is leafless, so cannot be determined. 



9. S. gazense, N. E. Br, A large shrub, very like S. Grantii in 

 appearance. Branches glabrous. Lieaves 4^G in. long, lJ-2 in. brpad 

 near the apex, cuneately obovate, acute or subobtuse, tapering from 

 j of the way up into a short stout petiole, narrowly revolute at the 

 margins and with the midrib prominent, but not wing-keeled beneath,
