in one row, of roughish bristles, slightly connate at base. DC. Prod. 5,

Herbs or half-shrubby plants, natives chiefly of S. Africa. Leaves alternate, 
toothed or entire. Heads corymbose, rarely solitary. Flowers all yellow, the rays 
sometimes paler than the disc. This genus differs from Erigeron (to which it is 
re-united by Schultz Bip.) in having ray-fl. “homochromous,” or of the same colour 
as those of the disc. Name from nidor, a strong smell, which these plants have.
