A climbing species, with subfiliform villous branches, having remote axils ; leaves 

 elliptic, cordate at the base, rounded and mucronately cuspidate at the apex, flat, entire, 

 membranaceous, reticulately veined, above green, pubescently hirtellous, with about 4 

 glabrous subulate glands at the base of the midrib, beneath softly and canescently 

 tomentose, lf-2 in. long, 13-14 lines broad, on channelled villous petioles 4-5 lines long ; 

 raceme lateral, aspergilliform, under 3 in. long, on a villous peduncle bearing few rather 

 large flowers on alternate hairy pedicels 1^ line long, each with a coloured, reticulate, 

 hirtellous, acuminate bract narrowed at the base, near an inch long ; sepals acuminately 

 lanceolate, subequal, flat, erect, 4 or 5 times shorter than the tube of the corolla, each 

 with an inner deltoid scale ; corolla orange-coloured, hairy outside, its cylindrical tube 

 pubescent inside, shortly cup-shaped in the mouth, and there furnished with a pilose 

 staminigerous ring ; segments oblong, inequilateral or dolabriform, with an acute tooth at 

 one angle, rounded at the other ; stamens seated on a pilose ring in the mouth of the 

 tube ; anthers cohering, quite exserted. 



The only flower examined by Kunth was in bud.

A lactescent shrub, with terete glabrous branches ; leaves elliptic-oblong, rounded at 

 the base, shortly acuminate, membranaceous, with entire subrevolute margins, green 

 above, smooth, reticulately veined, paler beneath, minutely scabridulous, 4-4J in. long, 

 lf-2 ia. broad, on glabrous channelled petioles 5-6 lines long ; raceme spicatiform, 

 lateral, erect, glabrous, 6 lines long ; peduncle covered from near the base with nume- 

 rous approximate, nearly sessile, spreading flowers, the size of those of Vinca rosea, each 

 supported by an acutely oblong, glabrous, coloured, deciduous bract 1 in. long ; sepals 

 short, roundly ovate, obtuse, glabrous, subimbricate, coloured, ciliate, each with an 

 inner basal scale ; corolla glabrous, its tube cylindrical, green, 1 in. long, lined below the 

 mouth with a sericeo-pilose ring ; limb funnel-shaped, cleft into 5 inequilateral reflexed 

 segments cuspidate at one angle, rounded at the other, sericeo-pilose about the mouth ; 

 stamens inserted in the top of the tube; anthers quite exserted, acuminate, shortly 

 2-lobed at the base, cohering in an erect cone ; disk of 5 fleshy lobes, subconnate at the 

 base, nearly as long as the ovaries ; follicles, in the immature state, slender, cylindrical. 



This and the preceding species differ from all the following in their very long bracts, 

 thus showing an approach of the genus towards Lasegwea.
