85. S. cruciata (Harv.); herbaceous, erect, glaucous, quite glabrous ; 
stem and branches terete ; cauline leaves cordate-clasping at base, many- 
nerved and netted-veined, tapering into a subulate, spinous point, with 
similar, subulate, long marginal spine-lobes, and rounded, perfectly 
smooth interspaces ; heads terminal, discoid; invol. se. longer than the 
dise, spinoso-subulate, bearing 1-3 pair of marginal, simple or geminate, 
long, rigid spines ; achenes silky-silvery ; pappus sc. biseriate, oblong, 
toothed. Stobea glauca, DC. l. ¢. 516. Rohria cruciata, Th. Cap. 619.

Apparently a tall, divaricately branched plant, quite herbaceous. Cauline leaves 
14-2 in. long, 4-1 inch wide at base, very rigid. It is very different from S. gla- 
brata. Why Lessing should have left it in Berkheya is unaccountable, as his own 
ae of the pappus, “ paleis obovatis, obfusis, denticulatis,” clearly indicates a 
36. S. glabrata (Th.! Cap. 620); stem herbaceous, robust, angularly 
compressed and ridged, thinly flocculent-tomentose or nearly glabrous ; 
cauline leaves cordate-clasping at base, netted-veined, glabrous or cob- 
webbed, acuminate and spine-tipped, with 3-4 lanceolate -subulate, 
spine-tipped lobes at base, the rest of the margin unequally spinous, 
with erose or denticled interspaces; heads terminal, discoid, glabrous 
or cobweb-woolly ; inv. sc. longer than the disc, lanceolate, acuminate, 
spine-margined at base ; achenes silky-silvery ; pappus scales 2-serlate, 
oblong, toothed. Less./ Syn. 67. DC. lc. 516.

‘ln pe pincoean, Bata Sa robably much branched. Branches filled 
with pate ern gpm Denes Lad amaaler . Leaves 2-3-4 in. long (lower leaves 
probably much larger), 14-2 in. wide, tapering from a broad base. Disc 1 inch or 
more in diameter. The sp. in Herb. Th. are flowering tops ; the lower and medial 
eauline leaves are unknown. No recent collector has sent this plant. 
37. §. pinnatifida (Th. Cap. 622); stem erect, terete, glandular- 
puberulous ; cauline leaves narrowed toward the earclasping base, 
deeply pinnatifid, concolourous, glabrous or beneath puberulous, the 
lobes semi-lanceolate, spine-pointed, the whole margin and the wpper 
surface (in a greater or less degree) set with slender, pungent spinules ; 
heads discoid, clustered or corymbose ; iny. sc. longer than the disc, 
semi-lanceolate, netted-veined, punctate, with binate basal spines and 
few or many marginal spinules; achenes thinly silky; pappus biseriate, 
short, denticled. Less. / Syn. 66. DO. l. €. 515.

Var. B. Voormansbosch, Swell.! Zey.! 3029. (Herb. Th., D., Sd.) 
Very variable in the size of leaves and fl. heads, and also in the spinules on the 
upper surface of the leaves ; these last are most abundant on the dwarfest specimens ; 
in luxuriant plants they are few and far between. The expanded invol., in Thwn- 
berg’s sp. is about } in. from tip to tip diameter ; in Ecklon’s from 1-14 in. ; and in 
Dr. Prior's, fally 2 inches and upwards! Yet all these specimens probably grew 
within the circuit of a couple of miles, and there is quite a gradation in other re 
Spects between them. Var. 8. has narrower inv. sc.; in foliage it precisely tallies 
with Thunberg’s original specimen.
