A subscandent plant, with slender, pallid, glabrous branches ; leaves oblong-ovate, cor- 
date, acuminate, membranaceous, 2 in. long, 9-10 lines broad, on petioles 3 lines long; 
racemes simple, axillary, pendulous, 6 in. long, fructiferous at the base, bearing above 
several alternate secund flowers, on pedicels 2 lines long, supported by lanceolate bracts 
1 line long; sepals broadly lanceolate, acuminate, 2-3 lines long; tube of corolla 1 in. 
long, greenish yellow, narrow at the base; segments obovate-oblong, crispate, subre- 
flexed, 6 lines long, yellowish, with crimson spots at their base ; follicles linear, torulose,

My specimen agrees well with Sir Wm. Hooker's drawing of a plant received from 
Rio de Janeiro, and cultivated in the Botanic Garden of Paris. It is a climbing species, 
near T. bicrura, with slender, terete, softly puberulous branches, with axils 3-3} in. 
apart; leaves opposite, oblong, narrowing below the middle, cordate and obtusely bilobed 
at the base, suddenly constricted at the summit into a short acute acumen, submembra- 
naceous, pale green above, rigidly and sparsely pilose above, the hairs growing out of 
scabridly globular prominences, ciliate on the margin, opake, and pale yellowish 
beneath, the reddish midrib, nerves, and transversely reticulate veins prominulent and 
furnished with long white very patent hairs, 2-3 in. long, {-1} in. broad, on sud- 
denly reflexed cano-tomentose petioles 3-5 lines long; raceme lateral, as long as the 
smaller leaves, on a hirsutely pubescent peduncle 9 lines long, bearing upwards about 
10 alternate subapproximate flowers, on hairy deflexed pedicels 2 lines long, with a 
short acute basal bract; sepals linear-lanceolate, very attenuated at the summit, thickly 
pilose outside, with membranaceous margins, each with an inner denticulate scale ; 
corolla, of a pale yellow colour, marked by roseate spots in the mouth, densely niveo- 
tomentose outside; tube cylindrical, 12 lines long, contracted 5 lines above the base, 
subcampanulate above; segments deltoid, dolabriform, with an acute tooth at the sinister 
angle, roundly expanded at the other side, and dextrorsely convolute, 4 lines long and 
broad.

A shrub with a striate stem and subfiliform, terete, glabrous branches, having remote 
axils; leaves ovate, membranaceous, upper ones narrower, cuneate at the base, ene 
at the apex, lower ones subobtuse at the base and acute above, 3-44 in. long, 2-23 in. 
broad, on petioles 6-9 lines long; racemes axillary, longer than the leaves ; peduncle 
bifid; pedicels 6 lines long, supported by ovate-lanceolate bracts, scarcely 1 line long; 
sepals ovate-lanceolate, patent, 2 lines long, each with an inner, trapezoidal, obsoletely . 
bidentate scale } line long; corolla yellow, glabrous; tube striate, 6 ae ue con-
