 from a perennial rootstock, erect, 6 in. long in the type, but probably 

 much taller, very stout, 4-5 lin. thick, branching into 4-5 cymes at 

 the top, thinly pubescent with short deflexed hairs (not prickles), and 

 marked with alternate leaf-scars. Leaves not seen. Cymes about 

 2 in. in diam., 3 times forked, on stout peduncles lJ-2 in. long and 

 J-J in. thick, beset with soft spreading prickles, which are entire on 

 the peduncles and more or less branched or scabrous with minute 

 points on the cyme-branches. Bract-cup oblique, J in. long and f in. 

 in diam., with the margins scarcely or not at all overlapping in front, 

 truncately rounded and shortly notched at the top, densely scabrous on 

 the middle part of the back and without evident keels, somewhat thick 

 in texture, with inconspicuous veins and the inner surface very minutely 

 papillate. Involucre 2-2J lin. long, open in front to below the middle, 

 subcylindric, faintly constricted just above the middle, truncate and the

 J-J in. thick, glabrous, smooth, probably somewhat fleshy. Leaves 

 l-l| in. long, 5-11 lin. broad or perhaps larger, narrowly oblanceolate 

 to elliptic, obtuse or acute, tapering from below the middle to a sessile 

 base or sometimes rounded into a very short petiole, crisped-undulate

 a few recurved soft prickles on the midrib beneath, deciduous. Cymes 

 2 or more at the apex of the stem on peduncles l|-3^ in. long, 

 2-6 times forked, 2-2^ in. in diam., with the peduncles and branches 

 beset with soft reflexed simple or scabrous prickles, otherwise glabrous. 

 Bract-cup oblique, 2^-3 lin. long and 4-5 lin. in diam., very broadly 

 or truncately rounded at the top, shortly notched behind, open in
