James! May-June.—Tree 50-80 feet high. Leaves about 1-3 feet long :
pinnffi 4-7; the lowest a single pair of leaflets, the others 7-13-foliolate;
leaflets mostly alternate. Legumes 6-10 inches long, nearly 2 inches wide.—

Flowers polygamous. Sepals 3-4-5, equal, united at the base.' Petals
as many as the sepals, or fewer by the abortion of one or two, or by the
union of the two lower ones. Stamens as many as the sepals and opposite
them, or by abortion fewer. Style short: stigma pubescent. Legume
stipitate, continuous, often intercepted internally between the seeds, dry or
with a quantity of sweet pulp surrounding the seeds. Seeds ov a l: testa
hard, crustaceous. Embryo yellowish, surrounded with a small quantity of
albumen : cotyledons flat.—Trees; the supra-axillary branchlets often converted
into simple or branched spines. Leaves abruptly pinnate or bipin-
nate (often on the same tree); the Leaflets somewhat serrate ! Flowers
small, greenish, spicate. The terminal flowers sometimes produce two
united ovaries, ex DC.
