small, 5-fid ; divisions acute, not ciliated. Corolla thrice the 
length of the calyx ; divisions oblong, subacute. Stamens very 
numerous, monadelphous for a short distance at the base, an 
inch in length, capillary, white: anthers roundish. Ovary ob- 
lp n o> greenish, smooth : style length of the stamens. Legume 
linear, compressed, with the edges incrassated, 9-10-seeded, 
tumid at the situation of the seeds, about 2i inches long : 
valves dry, when the pod is ripe revolute from the apex to the 
base : seeds oblongo-oval, compressed. 
This plant has been confounded with Mimosa comosa of 
Swartz. It is very different, however, from that plant. I have 
given the specific designation of Vespertinct to this species, from 
the circumstance that the flowers are at evening in their greatest 
perfection. Their long white filaments, which, during the heat 
of the day, hung down and were matted like tresses of hair, be- 
come erect, giving a singular starry appearance to the plant, 
and a slight but grateful fragrance is diffused. 
IS. Acacia villosa. Tedious Acacia. 
Unarmed villous, pinnae 6-paired, leaflets 10-16- 
paired oblong or ovate pubescent, petioles eglandu- 
lose, beads of flowers peduncled in threes axillary 
arranged to form a subterminal panicle.

HAB. Common, low hills on the South side of the Island. 
FL. Throughout the year. 
A shrubby tree, 6-8 feet in height ; branches sub-terete, of 
a brown colour, anguloso-striated, villous (approaching to hir- 
sute.) Pinnae 6- (rarely 5- or 7-) paired, about 3 inches long : 
leaflets 10-15-paired, scarcely petiolulated, oblong (the inner 
ones the smallest and of an ovate shape), somewhat unequila- 
teral at the base, subacute, pubescent : common petiole sub-3- 
gonal slightly channelled above, villous, eglandulose ; partial 
petioles sub-3-gonal, villous, with a pair of minute ovate scale- 
like stipels near their base. Stipules lanceolate, keeled on the 
back, villous, ciliated, deciduous. Peduncle snbterete, villous, 
3 together in the axillaj of the subterminal leaves, (forming at 
the end of the branches a kind of panicle), each bearing a some- 
what oblong head of about 15 white shortly pedicelled flowers. 
A small oblong solitary deciduous bractea situated on one side 
of the peduncle a little below the head. Calyx urceolate, mi- 
nutely 5-toothed. Petals 5, united to form a 5-partite corolla : 
divisions lineari-oblong, subacute, 3 times longer than the calyx. 
Stamens very numerous, 3 times the length of the corolla, de- 
licately capillary : anthers minute, yellow. Ovary stipitate, 
linear, compressed, glabrous : style rather thicker than the 
filaments. Legume short, plane, hairy.
