The plants and seeds were probably brought originally 
from the eastern frontier of Bengal, where it is indigenous. 
Trunk erect, though not very straight. Bark dark brown, 
pretty smooth. Branches numerous,speading in every direc- 
tion, so as to forma most elegant, large shady head. Leaves 
alternate, abruptly pinnate, sessile, generally more than a_ 
foot long ; when young, pendulous, and coloured. Leaflets 
opposite, from four to six-pair, the lower pairs broad-lan- 
ceolate ; the superior lanceolate ; all are smooth, shining, 
and of a firm texture, with their margins a little waved. 
Common petioles, round, smooth, Stipules axillary, solita- 
ry, in fact a process from the base of the common petiole, 
as‘in many ofthe grasses. Cymes terminal and axillary, 
between the stipule and branchlets, nearly globular, large, 
and crowded with flowers. Bractesa small, cordate, one 
under each division, and subdivision of the cyme. Pedun- 
cles, and pedicels smooth, and reddish-coloured. Flowers 
numercus, pretty large ; when they first expand, they are 
ofa beautiful orange colour, gradually changing to red, 
forming a variety of beautiful shades, fragrant during 
the night. Calyx two-leaved ; leaflets nearly opposite, 
coloured, cordate, bracte-like, marking the termination of 
the pedicel, or the beginning of the tube of the corol. Co- 
rol one-petalled, funnel-formed. Tube slightly incurved, 
firm, and fleshy, tapering towards the base, and imper- 
vious. Border four-parted ; divisions spreading, sub- 
orbicular, one-third the length of the tube ; margin 
slightly woolly. Nectary, a staminiferous, and pistilifer- 
ous, crenulated ring crowning the mouth of the tube. 
Filaments generally seven, and seven must, I think, be 
the natural number ; viz. three on each side, and one be- 
low; above a vacancy, as if the placeof an eight filament, 
.ecupied on its inside by the pedicel of the germ ; the fila- 
ments are equal, distinct, ascending, and about three, 
or four times longer than the border of ~ ry are ‘An-
