the anthers, and 5 fleshy laterally compressed processes with free obtuse tips 
adnate longitudinally to the backs of the anthers. Anthers large, horny, mem- 
branous tips large oblong ; pollen-masses one in each cell, elongate, compressed,

Stem 5-6 in., rigid. divided below. Leaves 4 by 1-4 in., spreading, exactly linear, 
acute, base cordate, midrib stout, nerves faint; petiole 45 in. Umbels clustered, 
many-fld.; pedicels 1 in.; bracts lanceolate. Sepals puberulous. Corolla 3-4 in. 
diam., purple within, glabrous.—A very remarkable plant, of which the specimen in 
Wallich’s Herbarium (from which fragments were sent to Wight) is the only one 
known. It is evidently near Hvlostemma and Asclepias itself.
