 duous gland; 5 oppositipetalous (or 10-15, 2, 3 opposite each petal) 

 sterile, subulate or very elongated linear, much exserted, coloured ; 

 all filaments monadelphous to a variable height. Ovary scarcely 

 stipitate co- ovulate ; style slender ; apex slightly dilated concave 

 stigmatiferous. Legume elongated, narrow at base, more or less 

 oblique, compressed coriaceous-ligneous, often very thick ; valves 

 becoming revolute by elasticity on dehiscence. Seeds broad com-
