somewhat cordate and rounded at base, suddenly attenuated towards the 
summit, with a short mucronate point, 5-nerved at base, the nervures and 
veins puberulous, opaque on both sides, and marked by numerous white 
lepidote scales. The terminal raceme is 24 to $4 inches long, 6 to 10- 
flowered, 4 pairs of primary pedicels, 4 lines each, bear 2 flowers on 
secondary pedicels, 3 to 4 lines long, bracteated ; these, together with 
the calyx and corolla, being covered with a dense yellow velvety down ; 
calyx campanulate, very coriaceous, 4 lines long, 4 lines diameter, with 
an almost entire margin, having 5 short exeurrent carinated nervures. 
The corolla, except the short basal consiriction, is covered with the 
same down, it is 1$ inch long, including its 5 short rounded erispated 
lobes. 
5. PITHECOOTENIUM BOTRYOIDES. D.C. 1. с, 195 :—Bignonia botry- 
> oides; Cham. Linn. vii, 700. San Раю (Weir, No. 128).. 
The branchlets are terete, compressed, the petioles and nervures of 
the leaves rufescently tomentose, the petiole is 15 to 18 lines, the petio- 
lules 3 lines long, the cirrhus 3 inches; the leaflets ovately oblong, 
obtuse and 8-пегүей at base, suddenly attenuated ‘at the apex, sparsely 
pubescent above, glaucously velutinous beneath, are 2 inches long, 13 
inches broad. The terminal raceme is 4 to 5 inches long, with numerous 
closely approximated opposite flowers upon articulated pedicels, 4 to 6 
lines long; the calyx 6 lines long, is coriaceous, bell-shaped, margin 
entire and much contracted in the bud; the very areuated corolla is 
velutinous, about 1} inch long, contracted beyond the calyx, subcam- 
panulate, with 5 crispate rounded lobes ; stamens included. 
The plants of Pithecoctenium are readily distinguished by their habit ; 
they are all climbers, and mostly clothed with a dense ochraceous tomen- 
tum; the leaves are generally coriaceous, either 3-foliolate, or conjugate, 
with a simple cirrhus ; on rare occasions, they are glabrous, and thin in 
texture. Тһе inflorescence is in terminal racemes of few handsome 
flowers, covered with velvety down; the calyx, almost cupular, with 5 
small teeth on a n entire margin is fleshy and downy. The tube 
of the fleshy corolla is always smooth within the calyx, beyond which it 
is suddenly enlarged into a campanular form, much arcuated and ven- 
tricose on the lower side, terminating in a border of 5 rounded crispated 
fleshy lobes, sometimes emarginated, and which are greatly imbricated 
in estivation. The stamens arise out of the basal contracted portion 
of the tube, from a ring of 5 velvety tufts of hair, they аге didynamous, 
with a short sterile 5th between the shorter pair, the filaments arch 
towards each other, the shorter pair not exceeding half the length of 
the tube of the corolla, the 2 anther-lobes are divaricated at right 
angles with the filament, and stand in a vertical position in collateral 
approximated pairs. The ovary, densely covered with stiff adpressed 
hairs, stands upon a large, fleshy, smooth, conical disk: itis 2-locular, 
the ovules biserial along the 2 corners of each cell, attached to the 
margin of the dissepiment. The structure of the flower is well
