 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 veiaed, canescent beneath, with soft shaggy 

 hairs, 2-2^ 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, H li^ie 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.

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, 2^ 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, acumiuately 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.

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, 2-2 J in. long, 3-7 lines broad, on shaggy channelled petioles 2 lines 

 long ; raceme lateral, including the peduncle 3 in. long, bracteate, all hirtellous ; pedicels 

 11 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.
