what membranous, nearly sessile, distant, elliptic-oblong, obtuse, 
mucronate, about 9 lin., rarely to 2 in. long, sparsely adpressed- 
hairy on both surfaces. Flowers few (3 or more) in a capitate 
ceyme on short slender erecto-patent peduncles rarely up to 
9 lin. long, with a pair of small lanceolate bracts subtending each 
head. Sepals subequal, eliiptic-ovate, shortly acute, back and margin 
sparsely hairy, barely 2 lin. long. Corolla white, 3 lin. long; tube 
narrowly funnel-shaped ; limb 5-partite; lobes spreading, blunt, the 
median areas hirsute. Stamens subequal, projecting at the mouth of 
the corolla; filaments narrowing gradually from the base, not dentate ; 
ovary hairy at the top; style bifid to the base; stigmas peltate, 
bilobulate. Capsule globose, glabrous, 14 lin. in diam. Seeds ovoid, 
dark brown, glabrous.—Hiern in Cat. Afr. Pl. Welw. i. 724.

12. S. schizantha, Hallier f. in Bull. Herb. Boiss. vi. 532. An 
erect, much-branched undershrub ; branches terete, subfuscous, sparsely 
covered with a minute adpressed pubescence, again branched above; 
branchlets slender, divaricate, subflexuose. Leaves very shortly petioled, 
ovate-elliptic, obtuse, minutely mucronate, 1 in. long, 4 lin. broad, 
grass-green, with sparse adpressed hairs on both surfaces. Peduncles 
about as long as the leaves, solitary or geminate in the leaf-axils, 
filiform, strictly erecto-patent, ending in a dense dichasium or a single 
unilateral cyme, collected into a panicle at the end of the branchlets ; 
bracts and bracteoles minute, lanceolate, approximate at the top of the 
peduncles; pedicels short, filiform, 1-14 lin. long. Flowers small. 
Sepals chartaceous, with a sparsely ciliolate membranous margin, sub- 
orbicular, 1 lin. Jong. Corolla 24 lin. long, whitish, cut down to the 
calyx into 5 ovate obtuse lobes, silky outside, except at the membranous 
edges, with adpressed unequally forked hairs. Stamens shorter than 
the corolla; filaments glabrous, abruptly dilated at the base. Ovary 
ovoid, hairy at the top with a few forked hairs; styles free; stigmas 
subpeltate, flattened, suborbicular with subemarginate base. Capsule 
glabrous, 4-valved ; seeds 4, minute, glabrous, black.
