LEGUMINOSJE-PAPILIONAGEJE. 319 



2-adelphous. Legume stipitate, ovate and thickly coriaceous at 

 base, few seeded indehiscent, produced above into a coulter-shaped 

 transversely veined wing, 1 sometimes with a thickened margin formed 

 by base of persistent style. Seeds 1-3, obliquely oblong, transverse, 

 rather curved, separated by a hard isthmus of pericarp ; embryo 

 exalbuminous ; radicle short curved. — Trees, handsome unarmed ; 

 leaves imparipinnate ; leaflets co, exstipellate, mostly alternate ; 

 stipules small caducous ; flowers 2 in loose branched terminal racemes ; 

 bracts small caducous ; bractlets {South America*). 



175. Centrolobium Mart. 4 — Flowers almost those of Tlpuana, 

 rather large ; calyx unequally toothed, imbricated. Wings and 

 petals of keel nearly similar, obliquely unguiculate. Stamens 10, 

 1-adelphous; filaments connate into a sheath cleft above and more 

 deeply divided below than laterally; anthers versatile. Grermen 2, 

 3-ovulate, much compressed and sterile at apex ; style slender curved ; 

 apex not thickened, stigmatiferous. Legume large samaroid inde- 

 hiscent, at base thickly coriaceous, inflated subligneous 1-3-seeded ; 

 higher produced into a falcate-oblong veined wing ; style persistent 

 hardened ; laterally spurred at base of wing. Seeds separated by 

 transverse or oblique septa, subreniform ; radicle curved. — Trees, 

 unarmed ; leaves imparipinnate ; leaflets opposite and alternate, 

 exstipellate ; stipules unevenly ovate, foliaceous caducous ; 

 flowers 5 in large branched terminal racemes ; bracts almost resem- 

 bling stipules, caducous ; bractlets narrow caducous [Tropical 

 America?). 



176. Pterocarpus L. 7 — Receptacle shortly turbinate, lined by a 

 disk ; mouth usually slightly oblique. Calyx gamosepalous ; 2 su-
