2-3 ft. high, straggling, with many long, lax, sparsely leafy branches, ending in 
a few corymbose heads. Tomentum sometimes very copious, sometimes scanty. 
141. S, persicifolius (Linn. Amoen. 6, Afr. 82); stem herbaceous, 
rigid, angular and striate, glabrous or cobwebbed, branching ; branches 
corymbiferous ; leaves scattered, ear-clasping, linear, entire, with strongly 
revolute margins, obtuse, glabrate above, woolly beneath ; corymbs 
closely few-headed, the pedicels short ; inv. of 10-12 glabrous scales, 
calycled and woolly at base ; heads 20~—30-f1., discoid ; achenes hispi-

Has. Cape, Thunberg! (Herb, Thunb.) 
Stem 12-18 inches high, slender, laxly branched ; the branches long, simple or 
divided, floriferous. Leaves scattered, subdistant, 1-11 inch long, not a line wide, 
but with well-developed basal ears. Pubescence cobwebby and fugacious. Heads 
5-10, in subglobose, dense corymbs. Inv. 3 lines long, shorter than the disc ; 
scales of the calycle brown-tipped. 
142. S. mucronatus (Willd. Sp. 1974); suffruticose, cobwebby-to- 
mentose, much branched, the branches eanescent, corymbiferous ; leaves 
half-clasping and often unidentate at base, linear-subulate, subpungent 
mucronate, with revolute margins, punctulate and glabrate (the younger 
cobwebby) above, tomentose beneath; corymb lax, compound, the pedi- 
cels copiously scaly below the head ; iny. calycled, of 14-16 glabrous,

A much-branched bush, 1-2 feet high, all the young parts copiously flocculent. 
Leaves 1-2 inches long, 1 line wide, from a broadish base, which is very frequently 
produced at each side into a tooth-like ear. Corymbs spreading, 10-20-headed. 
Heads 3 lines long. It much resembles 8. rosmarinifolius, but has discoid heads, and 
broad-based, often auricled leaves, &c. It is still nearer to S. juniperinus, from the 
narrow-leaved forms of which it only differs by the discoid heads.

A rigid suffrutex, 1-2 feet high, with the leaves and inflorescence of S. Burchellit, 
but discoid fl. heads. Leaves 1-14 inch long, 1 line wide, the auricle small and 
sometimes obsolete. Mrs. Barber’s specimens agree well with a poor one from Dreg% 
in Herb. Sond.
