772 ASCLEPIADEA (Brown). [ Emplectanthus. 
This curious genus is exceedingly like T'ylophora in general appearance and the 
species would probably be referred to it unless examined, but the corona is quite 
different from that of any Z'ylophora, and much resembles that of some species of 
Brachystelma and Caralluma ; the pollen-masses are also pellucid-margined as in 
those genera, whilst the follicles resemble those of the genus Riocreuxia, and it 
may possibly be of hybrid origin between that genus and Z'ylophora. The name 
is derived from ZumAekros, intermixed or perplexed, and avOos, a flower, in 
allusion to the combination of the characters of different genera upon one plant.

spathulate, or linear-lanceolate, obtuse, connivent-erect, sometimes 
only adnate up to the base of the anthers, at others up to their 
tips, dorsally connected at the base to the basal margins of the

broad-based open sinus and rounded lobes at the base, sprinkled 
with very minute hairs above, glabrous and paler beneath ; peduncles 
3-2 in. long, lateral at the nodes, glabrous, or puberulous on one 
side, bearing 1 or 2 distant fascicles of 4—6 flowers ; pedicels very

in dried flowers and invisible when wetted ; lobes about 14 lin. 
long, 1 lin. broad at the base, somewhat deltoid-ovate, acute,
