sessile, the lobes roundish, bearing 1-3-5 long spines and ciliato-spinel- 
lose, glabrous and glossy above, white-woolly beneath, rigid; upper 
leaves oblong, sinuate, spinous-toothed, decurrent in spinous stem- 
wings, uppermost cobwebbed above; inv. sc. tomentose beneath, 
pubescent above, longer than the disc, spine-pointed and set with long, 
strong marginal, often geminate, spines ; achenes glabrous, turbinate ; 
papp. sc. very small, separate, denticled. 
Has. Witbergen, 6-7000 f., Drege/ (Herb, D., Hk., Sd.) 
Stem 2-3 ft. high, pale, leafy to the summit, ending in a corymb of fl. heads. 
Cauline leaves 4-6 inches long, smaller upwards; the uppermost 1-2 in. long. 
Young leaves cobwebbed above. Very like S, scolymoides in general aspect, but 
with pubescent inv. sc. bordered with much stronger spines than in that species. 
6. 8. microcephala (DC.! 1. c. 520); stem erect, rib-furrowed, mi- 
nutely gland-pubescent, especially near the summit ; leaves glabrous 
above, white woolly beneath, the lowest elongate, tapering at base, 
toward the apex shortly and roundly sinuate-lobed, the lobes about 
3-spined, with ciliato-spinellose interspaces ; cauline decurrent in sinu- 
ous, ciliato-spinous stem wings, heads solitaryor sub-corymbose, ending 
nude, elongate, densely gland-pubescent branches, not bracteate ; inv. 
sc. somewhat longer than the disc, lanceolate, gland-pubescent outside, 
margined with slender solitary spines and ciliato-spinulate between; 
achenes glabrous, turbinate ; papp. sc. broadly ovate, 2-seriate, denticled.

Like other “common” plants, this has been rarely and very imperfectly collected. 
7. 8. discolor (DC.! 1. c. 520); stem herbaceous, erect, furrowed, 
chiefly toward the apex glandular pubescent ; leaves glabrous or 
minutely puberulous and green above, albotomentose beneath, the lower 
oblong-subobovate, tapering at base, sessile, sinuate-lobed, the lobes 
roundish, 3-5 spined, and spinellose between, cauline broad-based, 
decurrent in spinous-toothed stem-wings; branches corymbose, leafy, 
many-headed; heads (nude or) bracteate; inv. sc. glandular outside, 
ciliate with rigid, simple or geminate spines; achenes glabrous ; papp- 
sc, obtuse, denticled. °

8. 8. spherocephala (DC.! 1. c. 518); “stem herbaceous, erect, 
cobwebbed above; leaves on the upper surface spinelloso-scabrid, cob- 
webby beneath, the younger sub-canous, at length glabrate, sinuato- 
pinnatifid, the margin spinuloso-ciliate, the lobes roundish, the radical 
lys. tapering at base, cauline decurrent along the stem, in sinuate, sp!- 
nuloso-ciliate wings ; heads discoid, corymbose, pedicels tomentose; 
inv. much shorter than the disc, tomentose at base, sc. multiseriate, 
with several slender marginal spines.” DC. l. c.

I have seen but a leaf and a flowering twig. Achenes quite glabrous. Pappus 
of many, subbiseriate, separate, sharp-pointed, toothed scales.
