webby; radical leaves broadly obovate, cuneate at base, sessile, penni- 
nerved, on both sides minutely scabro-setulose, the subentire or repand 
margin unequally ciliate with long and short bristle-spines ; cauline lvs. 
decurrent, erect, smaller upwards, passing from oblong to linear, they 
and the narrow stem-wings also ciliato-aristate ; heads racemose, subses- 
sile; outer inv. sc. margined with Zong and short bristles, like the leaves, 
spreading, inner entire, lanceolate, nearly as long as the rays; achenes 
silky; papp. sc. biseriate, toothed.

25. 8. platyptera (Harv.); stem herbaceous, erect, simple, glabrous ; 
radical leaves obovate-oblong, cuneate at base, sessile? sparsely setulose 
above, glabrous except on the midrib beneath, the subsinuate margin 
unequally ciliate with slender bristles; upper cauline leaves (lower 
unknown) decurrent in very broad stem-wings, erect, oblong or linear, 
they and the wings ciliate with short, unequal spines; heads racemose, 
subsessile ; outer iny. se. squarrose-reflexed, narrow, ciliate with short, 
simple spines ; inner erect, entire, subulate, shorter than the rays;

Has. Umvoti, Natal, Gerr. ¢ MK. 1049. (Herb. D.) 
“Stem 3-4 feet high.” Rad. lvs. 5-6 in. long, 24-3 in. wide. Nearly allied to 
S. aristosa, but with much shorter bristles, wider stem wings, and squarrose outer 
iny. s8¢., &c, 
26. S. echinacea (Harv.); glabrous; stems closely leafy throughout, 
simple, herbaceous ; leaves much longer than the internodes, lanceo- 
late, acute, densely spinoso-setose above, and closely ciliate with unequal, 
slender spines, pilose on the midrib beneath, decurrent in long, sinu- 
ous, very spinous stem-wings ; heads shortly radiate, subcorymbose ; 
inv. se. shorter than the rays, subulate, bordered with mostly binate

larger flower-heads.
