Jonesia. heptandria monogynia. 219 



The plants and seeds were probal>ly 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,speadingin every direc- 

 tion, so as to form a most elegant, large shady head. Leaves 

 alternate, abruptly pinnate, sessile, j>enerally more than a 

 foot lung ; 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 of the grasses. Cymes terminal and axillary, 

 between the stipule and branchlets, nearly globular, large, 

 and crowded with flowers. Bracies a small, cordate, one 

 under each division, and subdivision of the cyme. Pedun- 

 cles, and pedicels smooth, and reddish-coloured. Flowers 

 numerous, pretty large ; when they first expand, they are 

 of a 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 terraiuation of 

 the pedicel, or the beginning of the tube of the corol. Ca- 

 rol one-ipetsd\ed,i'u.nnel-f or med. 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 pistilif6r- 

 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 place of an eight filament, 

 occupied 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 the corol. An-
