492 COMPOSIT (Harv.) [Stobea. 
margined with solitary spines; achenes glabrous; papp. sc. oblong 
obtuse.” DC. l. c. 
Has. Near the Zwartkops and Vanstaaden Rs., Uit. Drege. (Herb. Sd.) 
Of this I have only seen 2 leaves and a fl. head in Hb. Sd. ; it seems to differ 
from 8, petiolata chiefly in the copious snow-white wool of the under surfaces of the 
leaves. 
13. S. membranifolia (DC.! 1. c. 521); stem herbaceous, erect, fur- 
rowed, cobwebby above; leaves thinly membranous, glabrous above, 
albo-tomentose beneath, the radical on long petioles bordered with 
slender spines, oblong or elliptical, repand or sinuate-lobed, ciliate with 
slender, short, but unequal spinules ; cauline more copiously woolly 
beneath, furnished with longer and stronger spines and ciliato-spinellose 
between, more or less sinuous or pinnatifid, decurrent in ciliato-spinose, 
sinuous stem-wings; heads solitary, ebracteate ; inv. sc. longer than 
the dise, lanceolate, cobwebbed beneath, margined with many, slender, 
often geminate spines ; ach. glabrous, obpyramidal ; papp. uniseriate, 
toothed. 
Has. Uitenhage Distr., 2. ¢ Z./ (Herb. Sond.) 
Known from all allied species by the thinly membranous leaves, and slender 
weak spines. 
14. §. speciosa (DC.! 1. c. 518) ; stem herbaceous, erect, striate, 
glanduloso-setose, simple or corymbose at the summit, chiefly leafy 
below ; radical and lower leaves long petioled, the petiole aristoso- 
ciliate and sometimes winged or lobulate, the lamina either cordate, 
ovate or oblong, acute, scabrous above, white-tomentose beneath, ciliate 
with small, unequal bristles ; lower cauline shortly decurrent, upper 
sessile, (small), few, passing from lanceolate to linear, aristoso-ciliate ; 
heads 1-5, long-pedicelled, ebracteate, radiate ; inv. sc, linear-lanceolate, 
acuminate, glandular, ciliate with long spines; achenes glabrous, fur- 
rowed, obconic; papp. sc. biseriate, truncate, toothed.

15, 8. acanthopoda (DC. 1. c. 521); “stem herbaceous, erect, quite 
glabrous, flowering branches subcorymbose, the younger tomentose, at 
length glabrous ; leaves rigid, glabrous above (the younger cobwebbed), 
white-woolly beneath, the radical and lower cauline petioled, oval, 
sinuous-lobed, the lobes strongly 1-3 spined and ciliato-spinellose ; 
petiole armed with rigid, spreading spines ; cauline lvs. sessile, wider 
at base, adnate or very shortly decurrent ; heads pedicelled, ebracteate; 
inv, sc. tomentose beneath, linear, bearing geminate, marginal spines ; 
achenes turbinate, glabrous; papp. sc. oblong. 
Has. Betw. the Key, Gekau and Basche ; and betw. Omtata and Omsamwubo, 
Unknown to me ; seemingly a very distinct species. 
16. 8. epitrachys (DC. ! 1. c. 515); stems erect, subsimple, herba- 
ceous, cobweb-woolly, terete ; leaves spinoso-setose above and along the
