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 blanched above ; 

 branchlets slender, divaricate, subfiexuose. 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— 1A lin. long. Flowers small. 

 Sepals chartaceous, with a sparsely ciliolate membranous margin, sub- 

 orbicular, 1 lin. long. Corolla 2|- lin. long, whitish, cut down to the 

 calyx into 5 ovate obtuse lobes, silky outside, except at the membranous
