LEGUMINOS 2-0 SALPINIBA, 109 
Thus constituted,’ the genus Hymenea contains a dozen species? of 
which two belong to Zrachylobium’ and three to Peltogyne.s All are 
unarmed trees whose alternate leaves consist of two unsymmetrical 
coriaceous leaflets and five caducous stipules. Their flowers form 
ramified racemes (described by some as panicles) at the ends of the 
branches. The bract and pair of bractlets belonging to each flower 
usually fall very early. 
In Zachigah’ the flowers present the general characters of the 
preceding genera, but lack the lateral bractlets. The receptacle is 
cornet-shaped, lined with glandular tissue ; its mouth is oblique,* and 
on it are inserted five imbricated sepals,’ and as many alternating 
imbricated petals. The androceum consists of ten stamens, five 
superposed to the sepals and five to the petals, and inserted like 
them on the edges of the receptacle; each consists of a free filament 
reflexed in the bud and often velvety at the base, and a versatile in- 
trorse two-celled anther of longitudinal dehiscence. As in Amherstia, 
Schotia, &c., the gyneceum is inserted on the posterior wall of the 
receptacle ; its pluriovulate stipitate ovary is surmounted by a style 
slightly dilated at its stigmatiferous apex. The pod is oblong or 
elongated, compressed membranous and indehiscent. The oval com- 
pressed seeds have their embryos surrounded by albumen. Four or 
five species of Zachigali are known,’ unarmed trees from tropical 
America, whose alternate paripinnate leaves have two usually 
caducous stipules. . The flowers form racemes which are axillary or 
approximated to form terminal compound racemes. These plants 
form a connecting link between Améherstiee and Sclerolobiee, pos- 
sessing the excentric ovary of the former series with the general 
floral organization of the latter.

6 It is highest behind, so that it slants for- 
wards and downwards. Hence the bud as a whole 
is curved, the sepals bending outwards above. 
The same curved club-shaped flower-bud occurs 
in Schizolobium. 
7 Usually quincuncially, sepal 2 being anterior 
and sepals 1 and 3 posterior.
