478 COMPOSITE (Harv.) [ Gazania. 
A small species. Leaves 14-2 inches long, 1 line wide. Heads small and few-fl.; 
rays narrow. Allied to G. longifolia, Less., with which its inv. nearly agrees. 
17, G, heterocheta (DC. 1. c. 511); “stem half-woody, short ; sub- 
radical leaves tapering into a petiole, obovate, obtuse, sublyrate or 
variously pinnatisect, setose above, white-woolly beneath, the margin, 
chiefly near the base, ciliate with long bristles; pedunc. scarcely longer 
than the leaves, glabrous or sparsely bristled ; inv. campanulate, gla-

Has. Betw. Zilverfontein, Kooperberg, and Kaus, Drege! (Unknown to me.) 
18. G. pygmea (Sond.! Linn. 23, p. 69); crown woody, multifid ; sub- 
radical leaves hispid above, except the nerve white beneath, linear- 
spathulate, obtuse, tapering at base into a ciliate petiole, the margins 
revolute ; pedunc. glabrous, shorter than the leaves ; invol. glabrous, 
obconic, subtruncate. at base, the lobes 3-seriate, outer herbaceous, 
linear-acute, ciliate, inner ovate, subacute, short, with broadly membra- 
nous margins. 
Has. Magallisberg, Burke § Zeyher! (Herb. Hk., Sd.) 
Leaves (on the few specimens yet seen) all undivided, 2-3 inches long, 14-2 lines _ 
wide, rigid, erect, pale. Scape and inv. in Herb, Hook. quite glabrous; in Hb. Sd. 
minutely puberulous. Heads small: rays about 12, white, with a purplish band 
beneath. A specimen (Hb. Hk.) found by Burke on the Aapjes Riv. differs in the 
shorter and less ciliate outer inv. se. 
19. G. armerioides (DC.!1. c. 511) ; rootstock woody, many-cleft ; 
leaves subradical, linear (or a few pinnately 1-2-lobed), subsessile, with 
strongly revolute margins, setoso-mucronate, bristly above and on the 
margins, white tomentose beneath; pedunc. longer than the leaves, 
hairy; invol. broadly campanulate, very hairy, the sc. 3-4-seriate, the 
outer oblong or lanceolate, mucronate, inner much acuminate.

wide, in the stronger specimens sometimes pinnate-lobed, roughly hispid. Pedune. 
2-4 inches long. Invol. }-inch across. Rays numerous, pale, with a violet band 
beneath. In 8. (Herb. Hook.) all the inv. sc., but particularly the outer ones, are 
more taper-pointed. 
20. G. nivea (Less.! Syn. 49); very dwarf; rhizome woody, thick, 
divided at the summit; leaves crowded (subradical), petioled, hoary- 
tomentose on both sides, pinnatisect, the segments short, obtuse, linear, 
channelled ; pedune. not exceeding the leaves; inv. tomentose, truncate
