(Prevostea, Chois.; Seddera, Hoclist. and Stead.: Stylisma, Nutt.) 
Corolla campanulate, angular or shortly and broadly 5-lobed, folded in the bud.. 
Ovary 2-celled, with 2 ovules in each cell. Style bifid or divided to the ba^e, 
with a capitate stigma to each branch. Fruit a dry capsule. — Herbs or 
undershrubs, with erect prostrate trailing or twining stems, often tomentose or 
silky. — Leaves usually entire. Flowers axillary, solitary or rarely 2 or 3 together 
in the Australian species, the upper ones often forming a leafy spike, or in extra- 
Australian species the peduncles often several-flowered. 
The genus, as at present constituted, includes several species from tropical Asia, Africa, and 
America, but the Australian ones appear to be all endemic.
