Has. Cape, Thunberg. (Herb. Th., Sd.) 
Root fibrous. Stem divided near the base into several erect, simple branches, 
which are leafy in their lower part, nude and pedunculoid upwards. ‘Leaves slightly 
ear-clasping at base, 1-14 in. long ; their lobes 1 line wide. Pedunce. 4-6 in. long, 
swollen under the head. Inv. without calycle, but the expanded apex of the peduncle 
is minutely dentate, the teeth alternating with the inv. scales. Achenes narrow 
. obovate, copiously pubescent, their pubescence mucilaginous when moistened, emitting 
spiral hairs as in Ruckeria, &c. The style of the disc fl. is branched ; its branches 
tipped with a short, hispid cone. 
Doubtful species. 
C. arctotidea (DC. lL c. 306); ‘herbaceous, erect, the whole plant 
cano-tomentose when young, the adult cobwebby or glabrescent; lower 
leaves equalling the stem, long-petioled, lyrate, the terminal lobe reni- 
form, obtusely lobed, the lobes calloso-mucronate ; the cauline shorter, 
with petioles dilated at base; branches few, nearly leafless, one-headed ; 
inv. subcalyeulate, a little shorter than the disc, subcanescent; rays 
about 10 ; achenes compressed, downy, ciliate.” DC. 1. ¢. 
Has. Roggeveldt, Burchell, 1368. 
Drege’s specimens, from the Sneeuweberg, quoted by DC. are undistinguishable 
from C. mollis B.; I have not seen Burchell’s. P 
C. humifusa (L’Her. Sert. Angl. 25); “stem suffruticose at base, 
ascending ; radical leaves petioled, the petiole tomentose, not eared at 
base, naked or with a lobe under the limb, limb ovate or subeordate, 
or cuneate at base, lobulate-dentate, glabrous above, tomentose beneath ; 
pedune. scapelike, sparingly scaly, one-headed ; invol. calyculate, cob- 
webbed, of 10-12 scales; rays 8-10; achenes minutely downy, ciliate.”

Has. Graaf Reynet, Drege. (v. frustulum in Hb. Sd.) 
Is not this some form of C. mollis? 
CXI. LOPHOLZANA, DC. 
Heads many-fi., all the flowers tubular, 5-fid, with a terete tube ; the 
marginal fl. mostly cleft on the inner side and with subabortive anthers, 
thus polygamo-female ; of the dise regularly tubular, the style sometimes 
abortive. Jnv. 5-leaved, the scales free, leat-like, broadly keel-crested on 
the back, winged at the sides. Recept. honey-combed. Anthers tail-less.
