LEGUMINOSZ-CHSALPINIEZ. 141 
petalous corolla, a diplostemonous androceum, and a free gyneeceum. 
The calyx is divided to a variable depth into five lobes, valvate in 
the bud.’ The corolla, regular, or nearly so, is so imbricated, that 
the vexillary petal is overlapped on either edge. The stamens are 
subhypogynous and of two kinds. Those superposed to the petals 
are fertile, each formed of a free filament and an introrse two-celled 
anther dehiscing by two longitudinal clefts.” Those alternating 
with the petals are on the contrary sterile, consisting of an obpyra- 
midal body,’ or else a long slender staminode with a club-shaped 
head. The central gynzceum consists of a sessile or shortly stipitate 
pluriovulate ovary,‘ tapering above, to form avery short or almost 
obsolete style, whose scarcely dilated apex is covered with stigmatic 
papilla. The fruit is a flattened elongated pod with a thick woody 
endocarp, and divided by slightly projecting false dissepiments into 
as many chambers as there are seeds.’ ‘The endocarp separates into 
two flat elastic valves which then turn back, while the exocarp 
remains adherent in some species,’ but separates altogether from 
them in others.’ Within the membranous seed-coats is a greenish 
embryo surrounded by fleshy albumen.* Dimorphandra consists of 
some half-score species’ of unarmed trees from tropical America. 
The leaves are alternate, pinnate” or more frequently bipinnate, with 
ill-developed lateral stipules at the base. The flowers, each axillary 
to a little caducous bract, are small and numerous, in simple or 
ramified racemes, or spikes terminating the branches. 
In Burkea," from tropical and southern Africa, the subperigynous 
} The short thick lobes of the calyx often cease 
touching ata very early age, but in some species, 
like D. mollis, where they are longer, they are 
at first slightly imbricated. 
2 The filament is commonly attached by its 
very fine apex to an elongated, thick coriaceous 
connective, usually dark-coloured. The two 
linear cells occupy but a very narrow space on 
either side of the connective. 
3 In this case the tops of the five staminodes 
cchere into a sort of five-pillared vault. Only 
the filaments of the fertile anthers are to be 
seen in the interspaces between the pillars, the 
anthers being mainly lodged in the elongated 
pits on the inner faces of the staminodes. This 
is the case with the species of which TuLasnE 
(Arch. Mus., iv. 186) has made his section Po- 
cillum. In the other sections of the geuus (Zudi- 
morphandra Tut., loc. cit., 183; Phaneropsia 
TuL., loc. cit., 188) the staminodes are more 
slender above, and dilate at the summit into a 
little more or less oblique club-shaped head, often 
slightly concave or cupuliform above. 
4 The ovules are descending, with the micro- 
pyles superior and exterior. 
5 The fruit is one-seeded, it is said, in D. 
guianensis (D, Mora Brent. ;—Mora guianen- 
sis SCHOMB.).

8 The albumen is perhaps wanting in certain 
species, as BENTHAM gives the absence of peri- 
sperms as a characteristic of the genus.
