Stem herbaceous, erect, striate, subglabrous. Leaves sparsely setulose or glabrous 
on both sides, the midrib beneath pilose, rigid, pinnatipartite or deeply pinnatifid, 
the lobes in many pairs, ovate-subrotund, spinous-toothed, with smaller spines be- 
tween, curly undulate; the radical very long, tapering much at base, subsessile ; 
cauline shorter and the upper very short, decurrent in long, spiny, curly-sinuate 
stem-wings. Heads small, discoid, subcorymbose or panicled ; pedicels and base of 
inv. more or less woolly. Invol. sc. shorter than the disc, in many rows, subulate, 
margined with solitary slender spines. Achenes glabrous. Pappus sc. uniseriate, 
very short, at first concrete into a crenate, cup-like crown, afterwards separating. 
A specimen from Drege (Hb. Hk.) of Berkheya carduiformis, DC. is in all respects 
similar to Steph. carduoides, Less. DC. seems to have carelessly taken the long 
bristles of the receptacle for pappus ! 
CXXXVIIL STOBZA, Thunb. 
Heads many fl., either discoid, all the fl. tubular and perfect, or radiate, 
the ray-ft. neuter. Inv. sc. in many rows, concrete at base and tapering 
into a spinous point, bordered with 1-2 spines. Recept. honey-combed, 
the cells deep, nearly enclosing the achenes, cleft at the apex into 
bristle-shaped fimbrils. Stam. smooth. Achenes turbinate or inversely 
pyramidal, furrowed, either glabrous, downy, or villous. Pappus scales 
in I-2 rows, equal or the alternate narrower, oval, obtuse, toothed at 
the apex. DC. prodr. 6, p. 514. 
S. African thistle-like herbs or suffrutices, with much of the habit and characters 
of Berkheya, but differing in the bluntish not much acuminate pappus. Name in 
honour of Dr. Stobzeus of Lund, one of Linnzus’s earliest patrons.
