sometimes as narrow as the style, usually broader and discoid, marked 
by 3-5 angles or lobes. Fruit woody, capsular, 3—5-celled, 3—5-valved; 
valves separating from the thick axis, which is 3-5-angled or winged 
by the dissepiments that are opposite to the margins of the valves. 
Seeds in a double row close to the inner angle of the cells, without an 
arillus, flat, and winged, imbricated. Albumen thin and fleshy, or none. 
Radicle very small : cotyledons thin, foliaceous, large.— Trees. Leaves 
alternate, exstipulate, pinnated. Flowers panicled, bisexual, or usually 
unisexual from the abortion of the anthers or ovary. 
TRIBE I.—SWIETENIER. Juss. 
Corolla twisted in estivation. Filaments united into a tube. Hilum usually si- 
tuated at a distance from the embryo and at the apex of the wing which is then tra- 
— by the raphe ; rarely close to the embryo, the wing expanding in an opposite 
irection. 
I. SOYMIDA. Ad. de Juss. 
Sepals 5, imbricated. Petals 5, patent, shortly unguiculate. Stamen-tube 
cup-shaped, thickened upwards into 10 lobes, which cohere together by their 
base, but are free and 2-toothed at the apex, with an anther between the 
teeth: anthers nearly included, obovate, attached by their back at the apex. 
Ovarium seated on the disk, which is broader than itself and covers the bot- 
tom of the tube, 5-celled: ovules 12 in each cell. Style short, equal, 5- 
angled: stigma thick, peltate, 5-angled. Fruit capsular, oblong-obovate, 5- 
celled, 5-valved, dehiscing from the apex, septifragal: the thin woody sarco- 
carp in each valve becoming detached from the endocarp, and both from the 
large persistent axis that is 5-angled by the dissepiments. Seeds pendulous 
from the top of the axis, imbricated in each cell, flat, expanding on all sides, 
but particularly upwards (with the hilum at the extremity) and downwards, 
into a wing. Embryo nearly straight: cotyledons 2-auricled at the apex; 
radical conical, pointing upwards, concealed between the auricles of the co- 
tyledons.—Leaves abruptly pinnate : leaflets opposite, 3-6-pair, oval-oblong, 
obtuse. Panicles large, terminal, or in the axils of the uppermost leaves.

Calyx short, 5-toothed. Petals 5, erect. Stamen-tube cylindric-oblong; 
10-crenated, the crenatures each bearing 1 terminal anther: anthers ovate, 
exserted, erect. Ovary oblong, seated on a short disk of its own breadth, 
3-celled: ovules numerous in each cell, Style short, thick, scarcely distinct 
' in appearance from the ovary: stigma capitate, 3-lobed upwards. Fruit cap- 
sular, ovoid, 3-celled, 3-valved, dehiseing from the apex, septifragal: the 
woody sarcocarp separating from the endocarp, and both from the large per- 
sistent axis that is 3-winged by the dissepiments, Seeds numerous, imbrica- 
ted in a double series horizontally across each cell, flat, expanding down ware* 
(at the opposite extremity from the hilum) into a wing. Cotyledons orbicu-
