apex, slightly denticulate or fringed with a few glands along the top. 
Involucre about 3 in. in diam., cup-like, not notched on one side, with an 
erect entire rim-like gland, pubescent outside; lobes erect, overtopping 
the gland, glabrous, minutely ciliate. Ovary puberulous; perianth

8. S. glaucescens, Pax in Engl. Jahrb. xxxiii. 289, A shrub 
‘-8 ft. high. Flowering branches stout, }-} in. thick, apparently 
fleshy at the tips, glabrous, not glaucous. Leaves 5-6 in. long, 11-24 
in. broad, oblanceolate or cuneate-obovate, acute and apparently some- 
what recurved at the apex, tapering from above the middle into a 
stout petiole +4 in. long, with a wing-like entire keel }-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, 14-4 in. long, including the 3-2 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, 2-24 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 3-1 lin. ong, united to the middle, bifid at 
the apex, with slightly thickened stigmas. Capsule about 23-3 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 
«recurved pubescent pedicel. Seeds 1} lin. long and 1 lin. broad, slightly 
ire lai oblong-ellipsoid, brown, thickly covered with pale greyish

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 rim of 
the involucre lobed as originally described. Busse 165, from Mkatta River, referred 
to 8. glaucescens by Pax, is a totally different species, with the flowers in simple 
umbels of 3-5 rays, each bearing but one involucre, never forked, and the capsules 
bel larger, Tugose (not smooth), glabrous, and the seeds different. Possibly it may 
ong to S. Volkensii, Pax, but the specimen is leafless, so cannot be determined.
