162 Asclepiadaceae, 
lobes inflexed and usually forming a tooth on each side, nerver flat, 
with or without a tooth, horn or crest on the face of the lobe within 
the cavity or between the inflexed sides; sometimes 5 minute or 
rudimentary simple or bifid teeth or pouch-like lobules alternate with 
the coronal-lobes at their base. Staminal-column arising from the 
bottom of the corolla. Anthers erect, with their membranous appen- 
dages inflexed over the apex of the style or erect. Pollen-masses 
pendulous, solitary in each anther-cell, attached to the pollen-carriers 
in pairs by short or long variously-shaped caudicles. Style truncate 
or depressed and often umbonate at the apex, not exceeding the 
anther-appendages, which partly cover it. Follicles variable in shape, 
smooth or softly echinate. Seeds crowned with a tuft of hairs. — 
Perennial herbs or shrubs, often with a tuberous rootstock or tuberous 
roots; juice milky. Stems simple or branched, usually erect, rarely 
diffuse. Leaves opposite or whorled. Flowers in pedunculate or 
sessile umbels, lateral at the nodes or terminal. — Gomphocarpus,
