Capitula heterogamous, radiate; ray-florets female fertile in one 
row; disk-florets hermaphrodite sterile. Involucre campanulate in 
flower, hemispherical in fruit; bracts in about 2 rows, subequal. Re- 
ceptacle slightly convex, nearly flat, small, naked. Corollas of the ray

tip; corollas of the disk regular, tubular, funnel-shaped, shortly 5- 
cleft. Anthers appendaged at the apex, obtuse or mucronulate, not 
tailed at the base. Style of the ray-florets bidentate at the tip, of the 
disk-florets ending in a slightly enlarged entire globose stigmatic apex. 
Achenes of the ray at length thick, turbinate, somewhat incurved, hard, 
subterete, obscurely trigonous and somewhat ribbed. Pappus 0 or a 
mere ring at the top of the achenes.—Undershrubs or rigid herbs with 
alternate (rarely opposite) leaves and yellow flowers. 
A genus of about 38 species mostly confined to the Cape or Natal.
