LEGUMINOS2-PAPILIONACEZ1. 319. 
2-adelphous. Legume stipitate, ovate and thickly coriaceous at 
base, few seeded indehiscent, produced above into a coulter-shaped 
transversely veined wing,’ 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’ in loose branched terminal racemes ; 
bracts small caducous ; bractlets 0 (South America’). 
175. Centrolobium Marr.'—Flowers almost those of Tipuana, 
rather large; calyx unequally toothed, imbricated. Wings and 
petals of keel nearly similar, obliquely unguiculate. Stamens 10, 
l-adelphous ; filaments connate into a sheath cleft above and more 
deeply divided below than laterally; anthers versatile. Germen 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’ in large branched terminal racemes; bracts almost resem- 
bling stipules, caducous; bractlets narrow caducous (Zropical 
America’). 
176. Pterocarpus L.’—Receptacle shortly turbinate, lined by a 
disk ; mouth usually slightly oblique. Calyx gamosepalous; 2 su- 
1 «<The wing,” says BrenTHAM, “ought to 
be considered an appendage rather of the style 
than of the legume itself;” but on examination 
of the young fruit, the wing appears to us to 
arise from the same part as in Macheriwm, though 
not quite similar in shape. Hence the genus is 
asomewhat doubtful one, and to be distinguished 
from Macherium rather by the habit of the seeds 
and by the appearance of the plant, which is 
almost that of Bowdichia.
