linear-lanceolate, bearing solitary spines and ciliato-spinellose ; achenes 
glabrous ; papp. se. biseriate, oblong, toothed. 
Has. Betw. Hoffman’skloof and Driefontein, Albany, Drege. Uitenhage, Zck- 
lon! (Herb. Sd.) 
This seems to be little more than a glabrate form of S. polyacantha ; I have not 
seen Drege’s plant. 
2. 8. polyacantha (DC.! 1. c. 519); stem herbaceous, erect, furrow- 
striate, glabrate below, cobwebby above; leaves glabrescent above, 
the lower ones beneath cano-tomentose, the upper cobwebby-canescent, 
cauline pinnatifid, with subovate, 3-5 spined lobes, multispinellose 
between the spines, decurrent in spinous stem wings; heads solitary, 
radiate ; inv. sc. longer than the disc, cobwebbed beneath, margined 
with solitary spines ; achenes glabrous; papp. sc. biseriate, oblong, 
toothed. 
Has. Cape, Drege. Uitenhage, Ecklon! (Herb. Sond.) 
I have only seen Ecklon’s plant, which is scarcely at all cobwebbed, certainly nei- 
ther ‘cano-tomentose’ nor ‘canescent ;’ seems nearly the same as S. glabriuscula. 
3. 8. scolymoides (DC.! 1. c. 520); stem herbaceous, erect, glabrous, 
cobwebbed above; cauline leaves glabrous above, white-woolly beneath, 
oblong, narrowed to the base, decurrent in sinuous, spinous and ciliate 
stem wings, sinuous-lobed, the lobes short, 3-5 spined, with rounded 
ciliato-spinellose interspaces ; heads solitary, sub-pedunculate, ebracte- 
ate ; inv. sc. tomentose externally, longer than the disc, ciliato-spinose, 
whilst in flower patent-reflexed, in fruit suberect ; achenes glabrous, 
turbinate, papp. sc. oblong, obtuse, denticled. Rohria decurrens, Th. !

A tall eecknninhag species. Lower leaves 8-10 in. long, 1-2 in. wide, the 
younger sometimes cobwebbed above, afterwards nude. Spines strong and yellow- 
ish. Heads“ of large size; rays many, yellow. In Hb. Hk. is a specimen from 
Bowie that chiefly differs in having a much more woolly stem, and cobwebbed upper- 
surfaces to most of the leaves. Thunberg’s specimens of “‘Rohria decurrens,” though 
imperfect, agree very well with this ; their pappus is identical, of separate, toothed 
scales! by no,means ‘ coroniform,’ as described by Lessing. : 
4. §. helianthiflora (DC. 1. c. 520); “stem herbaceous, erect, fur- 
rowed, cobwebbed above; leaves glabrescent above, white-tomentose 
beneath, the lower tapering at base, sessile, pinnatifid, the lobes rounded, 
7-spined, sparingly spinellose between the spines ; cauline less sinuate, 
decurrent in spinoso-ciliate wings ; heads solitary, ebracteate ; inv. 
spreading, the sc. longer than the disc, cobwebby canescent beneath, 
with geminate marginal spines ; achenes glabrous, turbinate ; papp. 
se. oval, obtuse, denticled.” DC. l. c. 
Has. Zuureberg, 2~3000 f., Drege. (Unknown to me). 
This seems to border very closely on 8. scolymoides. 
5. S. cirsiifolia (DC.! 1. c. 519); stem herbaceous, erect, cobwebby 
at the summit; lower leaves elongate, pinnatifid, tapering at base, sub-
