descending. Legume of variable form; in some cases straight

 indehiscent or tardily 2-valved {Libidibia, Peltophorum, Coul- 

 teria), resinous subtorulose {Balsa mocarpon) ; sutures sometimes 

 thickened {Cinclidocarpus) ; in other cases legume 2-valved, 

 thin coriaceous, sprinkled with glands or short bristles [Erg/hro- 

 stemon, Hoffiuanseggia, Pomaria), straight or falcate ; or else eglan-

 straight with truncate apex and coriaceous valves {Sappania). Seeds
