Trees, often big* thorny. Flowers large, red, in dense racemes, 
usually produced before the leaves. Leaves trifoliate, large. 
Calyx oblique, spathaceous, splitting to base or campanulate 
2-lipped. Petals very unequal, slender, much longer than wings 
and keel. Upper stamen free nearly to base or connate with the 
others half-way; anthers uniform. Ovary stalked, many-ovuled; 
style incurved, beardless. Pod linear, turgid, torulose. Seed hard, 
brown or black. Species 25 to 30, tropics of both worlds. 
Those occurring inland and south of Kedah are probably 
remains of cultivation. E. indica, E. ovalifolia, E. siricta and 
E. lithosperma have all been planted for ornament, shade for cocoa, 
and for stakes for pepper, and the plants of these species seen in 
the south of the peninsula have probably been planted for some 
such reason. They are popularly known as " Dadap ” by Malays.
