Essential Character. — Sepals 5, persistent, unequal, somewhat in a double series: 
aestivation imbricative. Petals 5, inserted on the margin of the receptacle, deciduous, 
alternating with the sepals, of two kinds ; three outer ones orbicular, entire, with an imbri- 
cative aestivation; two interior smaller, acutely bifid, resembling scales. Stamens 5, oppo- 
site to the petals, and slightly united to them at the very base : three exterior sterile, 
opposite to the larger petals ; two interior fertile, opposite to the bifid petals ; filaments of 
the fertile stamens fiat : anther-cells globose, dehiscing transversely, placed side by side on 
the inner side of the saucer- shaped connective. Disk flat, thin, hypogynous, free except 
at its point of attachment with the ovary and receptacle. Ovary ovate, 2-celled ; ovules 2 
in each cell, superposed ; style simple, short, and thick ; stigma slightly 2-lobed. Fruit a 
1 -celled, 1 -seeded drupe; the dissepiment evanescent above, hardened and persistent at 
the base. Seed with a small cavity on one side, near the base. Albumen none, or extremely 
thin. Embryo curved: cotyledons thin, foliaceous, folded (chrysaloid) : radicle curved, 
pointing to the hilum. — Trees. Leaves alternate, without stipules, entire or rarely pin- 
nated. Infiorescence in panicles, terminal, or axillary near the extremity of the branches. 
Flowers small, inconspicuous, nearly sessile on very short peduncles that are arranged 
along the horizontal branches of the panicles. Wight and Arnott, 1. c. 
Affinities. The plants belonging to this assemblage are looked upon by 
Wight and Arnott as forming a family distinct from, but closely related to, 
Sapindacese. Tlie principal differences pointed out by those authors are, that 
in the latter the stamens are usually twice as numerous as the petals, which 
have scales or tufts of hair at their base ; and the hypogynous disk is fleshy. 
Other points are, indeed, adverted to, but they are either unimportant, or not 
clearly explained. These authors ‘do not take the same view of the structure 
of the genus as Roxburgh, but agree with Jack in considering the number of 
petals 5, of which three only are petaloid, and the other two bifid and adnate 
to the base of the two fertile stamens. It appears to me, however, that in 
reality, in M. simplicifolia at least, there is very great irregularity in the pro- 
portion of the parts of the flower ; in the calyx I find six pieces, two very 
minute and external, two larger, but unequal, next the first, and two more, also 
unequal, in the inside ; petals I see only three, on the face of the largest of 
which is a distinct trace of a rudimentary scale ; the stamens are five, three of 
them being deformed, lobed, and opposite the 3 petals, the other two fertile, 
alternating with two of the petals, with a membranous tooth on each side at 
the base (not the apex, as Roxburgh has it), and a remarkable saucer-like con- 
nective, on the upper face of which grow two anther-cells, the valves of which 
are extremely unequal. I do not, therefore, perceive how the genus differs 
from Sapindacese, except in the pistil being composed of two carpels instead of 
three. But although the number three is what usually prevails in Sapindacese, 
yet there are instances of two in Schmidelia, Irina, &c. and of four in Talisia 
and Dodonsea. 
In habit the genus Millingtonia resembles Semecarpus and Buchanania 
among Anacardiaceae.
