lated stigmatiferous. ‘Legume stipitate oblong-lanceolate flat 
thin, almost indehiscent. Seeds 1, 2, plano-compressed; albu-

14. Gymnocladus Lamx.—Flowers polygamo-dicecious ; recep- 
tacle long tubular, lined by a disk. Sepals 5, inserted at top of tube, 
valvate or unevenly imbricated. Petals 5, subsimilar to sepals, sub- 
equal imbricated. Stamens 10, free inserted with perianth ; anthers 
uniform introrse rimose, in female flower sterile. Germen inserted 
in bottom of receptacle, in male flower rudimentary, in hermaphro- 
dite and female oo-ovulate ; style terminal straight; apex obliquely 
dilated, sub-2-lobed stigmatiferous. Legume sessile oblong sub- 
falcate thick turgid, finally woody, 2-valved, pulpy within between

flower sterile. Germen central, in male flower rudimentary or 0, in 
female and hermaphrodite 2—-ovulate; style short; stigma ter- 
minal, more or less dilated. Legume ovate or elongated, straight
