pair ; leaflets 15-20 pair: stipules subulate: peduncles axillary, solitary, about 
as long as the leaves, naked ; bearing a globose few-flowered head: petals 5:

LXVIII. DICHROSTACHYS. DC. 
Flowers polygamous, bisexual and neuter. Calyx 5-toothed. Petals 5, 
distinet or united into a gamopetalous corolla. Stamens 10; filaments in the 
lower flowers of each spike sterile, linear and elongated: anthers of the fer- 
tile ones bearing a shortly stalked deciduous gland. Legume thick and 
coriaceous, curved and twisted, somewhat jointed, indehiscent; joints 1- 
seeded, scarcely separating naturally. Seeds naked.—Shrubs, often atmed 
with stipulary thorns. Leaves pinnated ; pinnæ 5-10 pair, with glands be- 
tween the lower ones: leaflets numerous, linear, pubescent. Flowers in ob- 
long-cylindrical axillary spikes: fertile stamens yellow, sterile ones white 
or variously coloured. 
Plants so very unlike Desmanthus in habit and every character, except the sterile 
flowers being neuter, that we feel rather surprised at their having been so long con- 
oined with it: we therefore separate them, and adopt the name given to the section 
y De Candolle as that of the genus. 
838. (1) D. cinerea (W. & A.:) thorns solitary: pinnæ of the leaves 8-10 
pair; leaflets ciliated, 12-15 pair: petioles pubescent: spikes usually solita-

leaves: petals scarcely cohering by their margins, and forming a 5-cleft co- 
rolla.— Wight ! cat. n..556,— Mimosa cinerea, Linn. sp. p. 1505: Roxb. Cor. 2.
