A climbing plant, with flexuous, slender, patently pubescent, fistulous branches, 1 line 

 thick, with axils 4^-7 in. apart, rarely with a very slender, unilateral, very pubescent 

 branchlet ; leaves ovate, rounded and deeply cordate at the base, with rounded lobes, 

 contracted below the apex into a subulately linear recurving acumen, fuscous green and 

 opake above, remotely hispid with rigid hairs bulbose at the base, patently cano- 

 hirsutiilous along the midrib, with about 16 pairs of divergent nerves and others shorter 

 and intermediate, with transversely reticulated veins, ciliate on the margins, paler 

 beneath, and more densely hispidulous, especially on the neryes, 2J-4J in. long (in- 

 cluding the basal lobes 3 lines long), l|-2 in. broad, on retrorsely hispid petioles 2 lines 

 long ; raceme solitary, lateral at the nodes, 3-4 in. long, patently hirsute, on a stoutish 

 divergent peduncle bare at the base for 1-lJ in., bearing upwards about 12 alternate 

 flowers on hirsute pedicels 2 lines long, each supported by a large foliaceous ovate bract, 

 substipate at the base, with an elongated, very narrow, incurved linear point, with coloured 

 nerves, densely pubescent beneath, 10 lines long, 4 lines broad ; sepals subulately linear, 

 very acute, with a reddish membranaceous margin, smooth inside, puberulous outside, 6 

 lines long, 1 line broad at the base ; coroUa of a deep scarlet colour when in bud, densely 

 clothed with white woolly hairs, afterwards subglabrous ; tube cylindrical as far as the 

 middle, funnel-shaped above, 10 lines long ; segments rhomboidal, much veined, uncinately 

 acute at the sinister angle, horizontally spreading on the dexter side, 6 lines long, 4 lines 

 broad ; stamens seated in the contraction of the tube, on a densely woolly niveous ring. 



A representation of this species, with an analysis of its flower, is shown in Plate XXV.

 Brit, sine loco (Sellow, infructu). 

 A climbing species, with simple, terete, flexuous, hirsute branches ; leaves oblong- 

 ovate, narrower below the middle, deeply cordate at the base, with rounded lobes, gra- 

 dually or more suddenly acuminate, chartaceous, fuscously olive-coloured above, opake, 

 subsparsely hispid, with adpressed soft hairs seated upon prominent rugous points, with 

 about 12 pairs of divergent semi-immersed nerves, ferruginously pallid and opake be- 

 ~neath, densely hirsutulous, especially on the midrib and nerves, and on the transverse 

 veins with patent more rigid hairs, 4|-5| in. long, 2|-2f in. broad, on patently hispid 

 petioles 5 lines long; raceme (according to Miiller) axillary, as long as the leaves, 

 pubescent, on a peduncle bare at the base for 1^ in., bearing several flowers on stout 

 subreflected pedicels, supported by as many linear-lanceolate pubescent bracts as long 

 as the pedicel and calyx ; sepals linear-lanceolate, subpubescent, 3^-4^ lines long, 1 line 

 broad at the base, each with an inner, ovate, subcrenate scale ; tube of corolla cylin-
