STREPTANTHUS (from streptos, twisted, and | 
anthos, a flower; alluding to the twisted claws of the 
petals in some species). ORD. Cruciferæ. A genus com- 
prising, according to Asa Gray, about thirteen species 
of hardy, glabrous, annual or perennial herbs, natives of 
mostly Western North America. Flowers purple, rarely 
white or yellow, ebracteate, rarely bracteate, sometimes 
pendulous ; two or all of the sepals saccate at base, often 
coloured, sometimes very broad; petals unguiculate, the 
claw straight or twisted. Leaves entire, or the lower 
ones lyrate-pinnatifid; cauline ones sessile or amplexi- 
caul. Two species have been introduced; both are

STREPTOCARPUS (from sireptos, twisted, and 
karpos, a fruit; the capsule is spirally twisted). Cape 
Primrose. ORD. Gesneracee. A genus comprising about 
a dozen species of pretty, stove or greenhouse, often 
villous or woolly herbs, sometimes stemless with spread- 
ing radical leaves, or rarely caulescent with opposite leaves 
(in some of the species, there is only one leaf in the adult 
state; this being, in reality, one of the cotyledons, which 
has developed to an enormous extent); they are natives 
of South and tropical Africa and Madagascar. Flowers 
pale, purplish, blue, or reddish, showy; calyx five-parted ; 
corolla tube straight, declined, or incurved; limb ob-
