A climbing plant, with filiform hairy branches, having remote axils; leaves oblong, 
rounded and cordate at the base, cuspidately acuminate, flat, membranaceous, above 
green and hispidly pubescent, reticulately veined, canescent beneath, with soft shaggy 
hairs, 2-21 in. long, 10-12 lines broad, on channelled tomentose petioles 4-5 lines long; 
raceme lateral, shorter than the leaves, pedunculate, hirtellous; bracts lanceolate, as 
long as the pedicel and calyx; pedicels hairy, 14 line long; sepals acutely ovate, erect, 
1 line long, each with an inner lanceolately ovate scale; corolla yellow, hirtellous ; 
tube 8-9 lines long, cylindrical, a little wider in the mouth, where it is sericeously 
pilose; segments inequilateral, shortly acute at one angle, rounded at the other; sta- 
mens inserted in the mouth of the tube, exserted; filaments short, broader above, pilose 
inside ; anthers linear, glabrous, emarginately bilobed at the base; disk urceolate, 
glabrous, partially cleft into 5 obtuse lobes, enclosing 2 ovaries; style, clavuncle, and 
stigmata as in the generic character; follicles 2, slender, terete, torulose, hairy, 3 in. 
long; seeds comose.

p. 218; A. DC. l. c. p. 461. Rio Orinoco: non vidi. ; 
A slender species, with terete hairy branches; leaves subovate, elliptic, cuspidate, 
cordate at the base, entire, membranaceous, above adpressed pilose, reticulately veined, 
beneath canescent, hirto-pubescent, 5 in. long, 24 in. broad, on tomentose channelled 
petioles 6 lines long; raceme lateral, much shorter than the leaves, pedunculate, few- 
flowered; bracts ovate-oblong, hairy, as long as the pedicel and calyx, canescently to- 
mentose; sepals hairy, shorter than the tube of the corolla, acuminately ovate, with an 
internal scale; corolla not larger than that of Vinca rosea, pubescently hairy outside ; 
tube cylindrical, a little swollen at the staminiferous sericeo-pilose ring in its mouth; 
segments inequilateral; stamens inserted in the pilose ring, exserted ; filaments, anthers, 
and other parts as in the preceding.

p. 460. Rio Orinoco: non vidi. 
A climbing species, with filiform hairy. branches, having very remote axils; leaves 
oblong-lanceolate, upper ones lanceolate, acuminate, rounded and cordate at the base, 
flat, above glabrous, shining, green, reticulately veined, beneath paler, hirtellous, with 
prominent nerves, 2-21 in. long, 8-7 lines broad, on shaggy channelled petioles 2 lines 
long; raceme lateral, including the peduncle 3 in. long, bracteate, all hirtellous ; pedicels 
13 line long, subulate; bracts of the same length ; sepals hairy, ovate-lanceolate, with a 
deltoid inner scale; corolla yellow, glabrous, its tube cylindrical, 8 times as long. as the 
sepals, a little swollen in the mouth, which is lined with a sericeo-pilose ring ; segments 
inequilateral, cuspidately acuminate at one angle, rounded at the other; stamens inserted 
in the pilose ring, exserted : the rest as in the preceding species.
