508 COMPOSIT# ( Harv.) [Berkheya. 
A remarkable species, unlike any other Berkheya, but with somewhat the aspect 
of Stobea Zeyheri, S. and H. Stem 1-2 ft. high ; the barren stems very densely, 
the flowering more laxly leafy. Leaves 14-2 in. long, not 1 line wide. 
19, B.? gazanioides (Harv.) ; stem herbaceous, rigidly setose ; leaves 
alternate, subdistant, oblongo-lanceolate, subacute, tapering at base, 
entire, rigidly setose above and on the midrib beneath, tomentose be- 
neath, rigidly-ciliate especially toward the base, but not spinous ; outer 
inv, sc. lineari-subulate, attenuate, sub-biseriate, pectinato-ciliate, inner 
much shorter, lanceolate, membr.-edged and purple-ribbed, ciliolate ; 
ovaries very silky ; papp. sc. nearly as long as disc-corolla, lanceolate, 
incised. 
Has. Damaraland, Mrs. Kolbe! (Herb. D.) 
Of this most remarkable plant I have only seen a single flowering branch, about 
6 inches long, bearing 3 distant leaves and a fi.-head closely subtended by 3 others. 
Leaves 2-24 in. long, 3-4 1. wide. Outer inv, sc. 1-14 in. long, } 1. wide. The 
* sete on all parts of the plant are rigid, but none are spinous. Rays many, longer 
than the inv. sc., yellow. In gen. char. it oscillates between Gazania and Berkheya ; 
but the inv. sc. are concrete at the very base only.

20. B. obovata (Willd. 1. c. 2269); glabrous ; leaves alternate, ses- 
sile, obovate or oblong-obovate, distantly spinous-toothed, pungent ; 
inv, sc. oblong or lanceolate, few-spined, the inner shorter and narrower; 
achenes silky ; papp. sc. very long, subulate, very much acuminate.

Has. Karroo, Thunberg! Drege! Kamnario, Mundt. (Hb. Th., Hk., Sd.) 
Readily known among its allies by the perfectly glabrous foliage. 
21. B. canescens (DC.! 1. c. 507); branches cano-tomentose ; leaves 
alternate, petiolate, elliptical or ovate, distantly spinous-toothed, on 
both sides thinly canous ; petiole at the base 3—5-spine-stipelled ; 
heads subcorymbose, pedicelled ; inv. sc. glabrescent, narrow, shorter 
than the rays, spine-bordered ; achenes silky ; papp. sc. bristle-shaped, 
tapering to a hair-like point. 
Has. Gariep, near Verleptpram, Drege/ (Herb. D., Hk., Sd.) 
Very like B. incana in general aspect ; but with larger leaves, smaller fl. heads, 
more glabrous iny. sc., and a very different pappus. A specimen from Drege (Hb. 
Sd.) marked “ B. fruticosa, c.” belongs to this species. 
22. B. corymbosa (DC.! 1. c. 507); branches cano-tomentose; leaves 
alternate, sessile or subpetiolate, on both sides cano-tomentose (or gla- 
brate/) sinuoso-pinnatifid or tooth-lobed, the lobes produced into long 
spines ; corymb compound, level-topped, many-headed ; inv. sc. about 
equalling the rays, lanceolate, glabrate, few-spined ; ach. silky ; papp- 
sc. bristle-shaped, tapering to a hair-like point. 
Var. 8. glabrata; leaves becoming glabrous on both sides. (Herb. Hk., Sd.) ° 
Has. Zilverfontein, Drege! Modderfontein, Rev. H. Whitehead/ B. Kamos, 
Zey.! 983. (Herb. D., Hk., Sd.) 
ves 14-2 in. long, 4 in. wide ; in more luxuriant specimens the lower leaves 
are subpetioled, the petiole with a pair of spine-toothed ears at base. Zeyher’s 983 
has nearly glabrous foliage !
