A scandent species, with dark costately striate scabridulous branches; axils 3-4 in. 
apart, dilated, with a short stipule on each side of the petioles; leaves oblong, rounded 
and deeply cordate at the base, gradually acuminate or more suddenly acute at the 
summit, submembranaceous, above fuscous green, opake, scabridly pruinose, with im- 
mersed nerves, beneath opake, yellowish hepatic, scabrid, and rigidly hirsutulous, 2}—4 in. 
long, 11-2 in. broad, on reflexed pubescent petioles 2 lines long; raceme lateral at the 
axils, 4 in. long; peduncle deflexed, 13 in. long, bifid at the summit, each branch bear- 
ing about 10 alternate flowers, on patent subpilose pedicels 6 lines long, having an acute 
bract $ line long at their base; sepals ovate, acuminate, subpilose, reddish, 3 lines long, 
13 line broad, each with 3 small lanceolate inner scales; corolla 24 in. long, violet below, 
upper portion of a deep rose-colour; tube 15 lines long, cylindrical and ventricose at the 
base for a length of 6 lines, there suddenly constricted, rather broadly cylindrical or in-

The drawing above figured in the ‘ Flora Brasiliensis’ was taken from a plant introduced 
into the Paris Garden from Rio de Janeiro. 1 found it in a living state at distant places 
in that province in 1830 and 1838, and then made drawings of it, its chief peculiarity con- 
sisting in its long pendent bifid raceme; its tortuous branches are fuscous, striate, and 
shortly hirsute, with dilated axils 4-5 in. apart, furnished on each side of the petioles 
with 2 small acute stipules ; opposite leaves ovate or oblong-ovate, rounded or some- 
what acute at the base, suddenly constricted into a short mucronulate acumen, membra-
