Cotula.] COMPOSIT (Harv.) 183 
_19. C, barbata (DC. Lc. 79); annual, cespitose, villous, with long 
silky hairs, the crown dividing into several very short, rudimentary 
stems ; leaves subradical and tufted, softly villous, petiolate, pinnati- 
partite above the middle, the lobes few, narrow-linear, simple or forked, 
callous-tipped ; pedunc, very long, scapelike, glabrous, heads many- 
flowered, homogamous; inv.-seales 10-12, the outer broadly ovate with 
membranous edges, the inner scarious, very obtuse; corolla tube longer 
than the bell-shaped limb, widely 2-winged, limb 4-toothed, the teeth 
granulated ; ovaries granulated (achenes not seen). 
Has. Betw. Zilverfontein and Kaus, 2~3000 f,, and near Lelifontein, Drege / 
(Hb. D., Hk., Sd.) ‘ 
United by Fenzl (Hb. Sd.) with C. nudicaulis, of which it has the habit ; but 
besides the copious pubescence, this differs in the form of the corolla and the surface 
of the ovary. Ihave not seen the achenes, but, judging by the ovary, they must 
differ greatly from those of C. nudicaulis. Tufts subglobose, 2 inches in diameter. 
Pedune. seapelike, 5~6 inches long. Heads 4-5 lines in diameter. I cannot find 
any female marginal flowers. 
20. C, Thunbergii (Harv.) ; annual, stem multifid at the crown; 
branches short, tufted, closely leafy, pubescent; leaves alternate, clasp- 
ing at base, long petioled, at the apex trifid or shortly pinnatisect, 
densely silky with soft, spreading hairs, the lobes linear, simple or 
forked, callous-tipped; pedunce, elongate, scapelike, glabrous; inv.-scales 
numerous, narrow-oblong, silky, one-nerved, brown-edged, with a nar- 
row membranous border; heads homogamous (the outer fl. commonly 
abortive), all fl. subsessile, with similar 4-toothed corollas; cor. tube 
narrowly winged, expanding at base into a short, spreading frill, which 
overhangs the ovary ; achenes compressed, wingless. C. sericea, Thunb.! 
in Herb. No. 2 (excl. Sp. No. 1). 
Has. Cape, Thunberg! (Herb. Th., No. 2). 
With the aspect and foliage of C. barbata, this has a very different involucre and 
structure of flowers; the frill at base of the corolla is evidently an appendage similar 
to that which envelopes the ovary in Otochlamys. Stems 1-2 inches long, densely 
tufted. Leaves about uncial, for } their length simple and petiolar, lobes 3—4 lines 
long. Pedune, 4-6 inches long. Heads 4 lines diameter. 
21. C. sericea (Thunb.! Cap. 696); perennial? lignescent at base, 
many-stemmed, tufted ; leaves on long clasping petioles, bi-pinnatipar- 
tite, densely silky with appressed hairs, lobes and lobules linear-terete, 
entire, obtuse ; peduncles long, scape-like, nude, 1-headed ; heads flat- 
tish-convex; inv. scales longer than the disc, glabrous, oblong, obtuse, 
- nerved, with a wide, hyaline, membranous border; heads homogamous, 
all fl. subsessile, with similar, 4-toothed corollas; cor.-tube compressed, 
slightly winged, shortly ear-frilled at base ; achenes compressed, wing- 
less. (C. sericea, Thunb.! in Herb. No. (excl. sp. No. 2). Tanacetum 
linearilobum, DC. 1. c. 133. 
Has. Cape, Thunberg ! Witbergen, 7-8000 ft., Drege! (Herb. Th., Hk.) 
Stems payee high, ascending, ‘tafted. pSatto 8 ere long, including 
the petiole. Pedune. 3-12 inches long. In Thunberg’s herbarium are two sheets 
marked “‘ Cotula sericea:” that marked No. 1 belongs to this species ; that marked 
No. 2 to our C. Thunbergii.
