Trees, usually with prickly branches, the leaves 3-foliolate, the petio- 
lules with prominent glands at their tips. Flowers large, red, in dense 
racemes. Calyx oblique, spathe-like, finally splitting to the base, or cam- 
panulate and 2-lipped. Petals very unequal, the standard longer than the 
keel and wings. Upper filament free nearly to the base, or more or less 
connate with others. Ovary many-ovuled; style incurved. Pod linear, 
swollen, contracted between the seeds or flattened at one end. (Greek 
“yed” in allusion to the large red flowers.) 
Species 30 or more, tropics of both hemispheres, 4 in the Philippines.

A diciduous tree reaching a height of 15 m, the branches and branchlets 
stout, armed with short, few to many, sharp prickles. Leaflets broadly

Racemes terminal, pubescent, dense, up to 25 cm long. Flowers large, 
numerous. Calyx about 4 cm long, minutely 5-toothed at the tip, mouth 
very oblique. Petals bright-red, the standard 7 to 9 cm long, the wings 
and keel subequal, shorter than the calyx. Pod 10 to 25 cm long, 1.5 to 2 
em in diameter, distinctly constricted between the seeds. (FI. Filip. 
pl. 217.) . 
Common, fi. Jan—Apr., quite or partly leafless at time of flowering; 
throughout the Philippines, especially near the sea. India, through Malaya 
to Polynesia.

A tree reaching a height of 10 m, the trunk with large, conical protu-

obtuse, base acute or rounded. Racemes 10 to 20 cm. long. Calyx pubes- 
cent, 2-lipped, about 1 cm long. Petals dull-purplish-red, the standard

em long, with a elongated slender stalk. (Fl. Filip. pl. 345, E. lithosperma.)
