This species, described by Miiller, is scandent, with slender, glabrous, fuscous branches, 

 densely verruculose; leaves broadly ovate, roundish, and subcordate at the base, sud- 

 denly and shortly acuminate at the apex, membranaceous, glabrous, fuscous -green 

 above, with about 5 pairs of ascending semiimmersed nerves and reticulated veins, pale 

 ferruginous and opake beneath, with subprominulent nerves, and sulcate over the 

 immersed reticulated veins, 4-5 j in. long, 2j-2| in. broad, on rather slender chan- 

 nelled petioles not 6 lines long ; inflorescence terminal (or lateral at the ends of the 

 younger branches), pyramidal, with few ramifications, each branchlet rather laxly 

 flowered, the flowers nearly 2 lines long, on short bracteolate pubescent pedicels ; 

 sepals acutely ovate, half the length of the corolla, pubescent, cUiolate on the margins, 

 without inner scales ; corolla ferruginously tom'entellous ; tube very short ; segments 

 oblong-ovate, erecto-patent, hispidulous within, twice the length of the tube ; stamens 

 exserted ; anthers rigidly hairy behind ; disk 5-lobed ; foUicles 2, 14 in. long, torose, 

 glabrous, fuscous, having about 8 very narrow long strangulations between as many sub- 

 acutely ovate seminiferous sweUings, which are subnitid and costately striate outside.

(Riedel 1101) : v. s. in herb. Mus. Brit. Brazil (Sellow). 



A scandent plant, whose branches are cinereous, trichotomous ; branchlets slender, 

 fuscous, glabrous ; leaves oblong-ovate or ovate-lanceolate, subacute at the base, shortly 

 acuminate, submembranaceous, subglabrous, or obsoletely puberulous, opakely pallid- 

 green above, glaucous, with 5-6 pairs of fine prominulent nerves, with others inter- 

 mediate, aU arcuately conjoined, pale-green beneath, with reddish prominulent nerves 

 and reticulate veius, 2|— 3|- in. long, 10-12 Hues broad, on slender glabrous petioles 

 3-4 lines long ; panicle subterminal, 3 in. long, branching from near the base, the lower 

 branches short, increasing upwards, where the branchlets are again divided and thickly 

 flowered ; flowers approximate, on slender pubescent pedicels 1 line long ; sepals acutely 

 ovate, puberulous, f line long ; corolla fulvo-puberulous outside, 2 lines long ; tube very 

 short, it and the acutely ovate segments hispid inside.

V, s. in herb. Mus. Brit. Iguassu, prope Estrella (Bowie & Cunningham) . 



A slender climbing plant, with glabrous, striate, brown branchlets, their axils 1 in. 

 apart; leaves oblong-lanceolate (upper, young ones narrowly lanceolate), acute at the 

 base, with a short broadish subobtuse acumen, membranaceous, scabridulous, fuscous- 

 green above, with 4-6 pairs of remote ascending nerves, subferruginous beneath, 

 opake, with prominulent reddish nerves and densely reticulate veins, 2-2f in. long, 

 6-10 lines broad, on slender petioles 2-3 lines long ; panicle racemose, terminal on the 

 young branches, 2| in. long, oppositely branched at distances of 6 lines ; branches 

 ■|~1 in. long, bare at the base, patent, again shortly divided and bearing several approxi- 

 mate flowers on pedicels 1 line long ; sepals acutely ovate, subpHose, ^ line long ; corolla 

 subpilose, 2 lines long ; tube very short.
