BONPLANDIA TRIFOLIATA. ORD. Rutacez. , 121 
feet.t The trunk is cylindrical, branching towards the top; the branches 
numerous, alternate, and the upper ones spread nearly horizontally; both 
trunk and branches are covered with a grey-coloured bark. The leaves arise 
alternately on the branches, are about two feet long, independent of the pe- 
tiole, and composed of three oblong, ovate leaflets, pointed at each extremity, 
and attached toacommon petiole, from ten to twelve inches inlength,and chan- 
nelled. The flowers are produced in terminal racemes, composed of alternate 
peduncles, bearing from three to six flowers each. The calyz is inferior, 
persistent, five-toothed, and tomentose ; the corolla funnel-shaped, composed 
of five petals, so united below, as to appear to form one tube, with a five- 
cleft, spreading border ; the nectary consists of five glandular bodies, cover- 
ing the base of the germen; the stamens are shorter than the petals; the 
filaments are white, and support yellow anthers; the pistil is formed of five 
oval, hairy germens, with a single style, supporting five, fleshy, green stigmas. 
The fruit consists of oval, bivalved capsules, each containing a single seed.+

The Bonplandia trifoliata is a native of South America, growing abun- 
dantly in the woods, near the eastern bank of the Carony, at the foot of the 
hills that surround the Missions of Capassui, Alta Grecia, and Upata; it 
also grows west of Cumana, in the Gulph of Santa Fé, and Neuva Barcel- 
lona. The bark of this tree has been long known in commerce, under the 
names of cusparia and angustura ; the latter of which is derived from Angos- 
tura, and the former, probably, from Capassui, where it is collected. | 
* Pr. Hancock, who traversed repeatedly, and resided during several months, in the 
Missions of Carony, where he had an opportunity of seeing many thousands of the trees 
which produce the Angustura bark, says, “ that it seldom or never exceeds the altitude 
of twenty feet; the usual medium being about twelve or fifteen feet. The diameter of the 
trunk, which is tolerably erect, is from three to five inches. The parts of fructification 
also differ very materially from Humboldt's description.”"—Vide Transactions of the

This appendage is so elastic, that it is difficult to preserve the 
strong and horny arillus.”
