326 NATURAL HISTORY OF PLANTS. 
plano-compressed, o-seeded, longitudinally 4-winged, each suture 
transversely produced at each side into a broad membranous veined 
wing, seeds oval compressed.—A tree; leaves and inflorescences’ 
of Lonchocarpus; bracts caducous; bractlets 2, lateral, inserted on 
pedicel, opposite subelliptical subcoriaceous’ (Mezico, Morida, West 
Indies’), 
187, Coublandia Ausu.'—Receptacle depressed obconical, slightly 
oblique, lined by a disk. Calyx gamosepalous, broadly tubular, 
either evenly truncate or very shortly 5-toothed. Petals unguicu- 
late; standard suborbicular or broadly ovate, exappendiculate ; 
wings unevenly oblong, slightly adhering to keel; keel curved 
obtuse. Stamens 10, 2-adelphous (9-1) at base; vexillary stamen 
afterwards closely connate with remainder into a closed tube ; anthers 
versatile, minutely apiculate. Germen shortly stipitate ; ovules  ; 
stvle slender curved ; apex minute stigmatiferous. Legume either 
moniliform thick fleshy-corky subterete, constricted between seeds, 
or by abortion subglobose 1l-seeded, indehiscent. Seeds subovoid, 
scarcely compressed, laterally affixed; embryo fleshy; radicle in- 
flexed.—Trees ; leaves alternate imparipinnate; leaflets opposite ; 
stipules very small; flowers’ in axillary or lateral racemes, scattered 
or in pairs along rachis; bracts and bractlets very small, caducous 
(Mexico, South America’). 
188. Platymiscium Vo«.’—Receptacle obtuse or turbinate at 
base, lined by a disk. Calyx gamosepalous, shortly and nearly 
equally 5-toothed. Corolla almost that of Plerocarpus ;° wings free ; 
keel straight or slightly curved, petals dorsally connate at apex. 
Stamens 10, either l-adelphous, sheath cleft above, or more rarely 
2-adelphous ; anthers versatile ; cells often confluent at apex. Germen 
long-stalked, inserted in bottom of receptacle; ovule 1, descending ; 
1 Flowers whitish mixed with blood-red; calyx
