deltoid lobes. Petals oval, acute, glabrous. Stamens exserted ; an- 
thers broadly obovate-rotundate with a sessile non-exserted triangular 
gland between the slightly divergent apices of the cells. Ovary and 
style laxly patent-pilose. Legume 4—6 in. long, 1 in. in diameter, 
subcylindrical or but slightly compressed, straight, obtuse, smooth 
with a thick woody pericarp thinly septate between the transverse 
seeds. Seeds oblong or ellipsoidal, shining, with a faint areole on each 
side; embryo between thick lateral layers of albumen.—P. lanceolata,

Prosopis? dubia, Guill. et Perr. Fl. Seneg. i. 242, is referred in “ Niger Flora’’ to 
Acacia. Ido not know it. It is described as a tree of 40 ft., with virgate glabrous 
branches, geminate straight stout stipular spines; pinne 15~-20-jugate, leaflets multi- 
jugate linear obtuse, 14 lines long. Legume linear compressed coriaceous 10-12-seeded. 
2. P.? Kirkii, Oliv. A large tree; extremities unarmed, glabrous 
or obsolete-puberulous, slightly furrowed when dry, with pale ashen 
bark. Pinnwe 6—7-jugate, with a sessile gland between the pinne, 
rachis puberulous above. Leaflets 10—17-jugate, subsessile, oblong, 
obtuse, minutely pubescent, }—1 in. long, 1 line, more or less, broad. 
Flowers in solitary axillary spikes 4—6 in. long (apparently insect- 
punctured in our specimens), Legume 5-8 in. long, 1 in. broad, flat, 
coriaceous, circinate, with a short hooked apiculus. Seeds compressed, 
ovate, with a shining testa and faint areole on each side, separated by 
narrow interposed cellular partitions of the endocarp. Albumen 0.

Flowers sessile, 5-merous, in dense cylindrical spikes, the upper 
hermaphrodite, the lower neuter with long much exserted filiform sta- 
minodes. Calyx shortly toothed. Petals valvate, more or less con- 
nate. Stamens 10, hypogynous, free, exserted; anther oblong or 
elliptical with a globose caducous often slenderly stipitate apical gland ; 
“‘pollen-grains 00.” Ovary subsessile, multiovulate; style slender, 
stigma terminal, minute. Legume linear, compressed, coriaceous, 
twisted, indehiscent or irregularly opening; valves continuous, usually 
depressed between the seeds. Seeds compressed, shining; embryo 
betwc en thin lateral layers of pellucid albumen.—Shrubs or small trees, 
usualy spinescent. Leaves bipinnate, leaflets numerous, usually small, 
sessile. Spikes axillary, pedunculate, usually geminate or solitary ; 
hermaphrodite flowers yellow; neuter pink, white or purplish. 
A small genus of the Tropics and Australia. The following species are endemic, 
though D. nutans is widely dispersed between the Tropics in Africa.
