glabrous, or minutely puberulous. Zhunb./ Cap. 679. DO./ l.c. 391; 
also S. polyanthemus, DC. 1. ¢. 
Var. a. genuinus; leaves linear-subulate, with strongly-revolute margins, entire. 
Van. 8. salicinus (DC.); leaves flattish, lanceolate, with recurved margins, entire 
or subentire; minutely glabrous-dotted above. 
Var. y. epitrachys (DC.); leaves less expanded, with more strongly-revolute 
margins and more scabrid; entire, or here and there toothed. 
Var. 5. cruciatus; leaves (some at least) above the middle furnished with a pair 
of —_— spreading lobes, like the arms of a cross. 8S. cruciatus, Linn. f. Thunbd.!

Has. Cape, Thunberg! &c. Uitenhage, LZ. § Z./ Zey./ 2945. Zuureberg, Storm- 
berg and Witberg, Drege! Hassaquaskloof, Zey.! 2952. (Herb. Th., D., Sd., Hk.) 
Stems rigid and strong, but scarcely ligneous, except at base; the branches nume- 
rous, more herbaceous, but wiry. Branches and leaves more or less cobwebby, 
becoming nude. The leaves vary in length and breadth and degree of expansion, 
and in being sparingly toothed or entire; I find them constantly scabrous-dotted 
above, even in var. salicinus (Drege’s specimens). Drege’s var. “ subserratus” appears 
to me to belong rather to S. pterophorus. Inflorescence generally widely spreading 
varying very much, however, in the number of heads. Var. 5. cruciatus, is rather a 
monstrosity than a genuine form. 
105. S. ederiefolius (DC.! 1. c. 391); stem erect, rigid-herbaceous 
striate, scaberulous, the young parts cobwebbed, branches erect virgate ; 
leaves sessile, half-clasping, and slightly adnate at base, ovate-oblong or 
ovato-lanceolate, acuminate, rigid, sharply and distantly toothed, with 
teflexed margins, scaberulous, glabrous and glossy above, white-woolly, 
(at length nude) beneath; heads either solitary, terminal or 2~5 in a 
corymb, radiate, over 100-fl.; rays 12-15; inv. amply calycled, flat- 
bottomed, of many glabrous or cobwebbed scales; achenes minutely 
granulated. 
Has. Vanstaadensberg, Uit., £. § Z./ Zey.! 2944. (Herb. D., Sd., Hk.) 
A branching, bushy, but not ligneous, plant, 1-2-ft. high ; with straight, erect, leafy 
one or few-headed branches. Leaves 3-14 inch long, 5-6 lines wide, erect, very 
rigid. Heads 5-lines across. Similar in foliage to S. ilicifolius, from which it is 
known by its fewer and larger fi. heads. 
106. 8. arniceflorus (DC.! 1. c. 390); stem suffruticose, ascending, 
cobwebby, closely leafy below, subsimple, (either 1-3-headed or) corym- 
biferous and subpedunculoid at top; leaves oblong, sessile and sub- | » i 
decurrent, rather narrowed to the base, entire or sparsely few-toothed, 
with revolute margins, mucronate, cobweb-woolly beneath, scaberulous . 
and thinly cobwebbed, becoming glabrate above; upper leaves lax, 
small, linear, erect, acuminate; corymb simple or branched, few or ~ ‘e 
several headed, the pedicels long, bearing 2-3 subulate leaf-scales ; 
heads many-fl.; rays 10-12, spreading; inv. calycled, cobwebbed, of 
many narrow scales; achenes (young) pubescent. * 
Has. Auteniqualand, Burchell. Cape, Bowie? Groenekloof, and near Cape 
VAquillas, Drege! Near Simonstown, C. Wright, 302, 303. (Herb. Hk., D.) 
Stems 8-12 inches high. Leaves 1-2 inches long, 3-6 lines wide, with strongly 
revolute margins. Whole plant cottony-cobwebbed. Heads 4-5 lines across, yellow. 
T have not seen Burchell’s plant, which may differ, for DC. speaks of a “valid 
mucro” to the leaves and “‘ 1-2 sessile fl. heads,” characters which do not exist in 
Dregés specimen in Hb. Hook. The pedicels are corymbose, 1-14 inch long; the 
mucro is small and not always obvious.
