The Bonplandia Trieoliata is a native of South America, 
growing abundantly in the woods, near the eastern bank of the Ca- 
rony, at the foot of the hills that surround the missions of Capassui, 
Alta Grajcia and Upata : it also grows west of Cumana, in the Gulf 
of Santa Fe and Neuva Barcellona. The bark of this tree is known in 
commerce under the names of Cusparia and Angustura ; the latter 
of which it derived from Angostura, and the former, probably, from 
Capassui, from whence it is collected.

the height of from sixty to eighty feet ; the trunk is cylindrical, 
branching towards the summit, and covered with a grev-coloured 
bark ; the branches are numerous, alternate, and the upper ones 
spread nearly horizontally; the leaves arise alternately on the 
branches, are about two feet long, independent of the petiole, and 
composed of three oblong, ovate leaflets, pointed at each extremity, 
and attached to a common petiole from ten to twelve inches in 
length, and channelled; the flowers are produced in a terminal 
raceme, composed of alternate peduncles, bearing from three to six 
flowers each; the calyx is inferior, persistent, five-toothed, and 
toraentose ; the corolla is funnel-shaped, composed of five petals, 
so united below as to appear as one tube, with a five-cleft spreading 
border; the nectary consists of five glandular bodies, covering the 
base of the germen ; the stamens are shorter than the petals ; the 
filaments are white, and support yellow anthers ; the pistil is formed
