feet or 12 feet in height, and is usually of lax and slender growth,
but perfectly hardy.
C. CRUENTA (_syn C. orientalis_ and _C. sanguine_).--Oriental Bladder
Senna. Levant, 1710. This is a free-growing, round-headed, deciduous
bush, of from 6 feet to 8 feet high when fully grown. The leaves are
pinnate and glaucous, smooth, and bright green above, and downy
beneath. Flowers individually large, of a reddish-copper colour, with a
yellow spot at the base of the upper petal. The fruit is an inflated
