Probably a shrub, with scandent, slender, dark, pubescent branches, with axils 3^ in. 

 apart, having caducous stipules ; leaves elliptic-oblong, obtusely acute and emarginate at 

 the base, furnished at the apex with a short subacute acumen, rigidly chartaceous, fuscous- 

 green above, obsoletely puberulous, with slender immersed nerves, paler beneath, glaucous- 

 pruinose, subhirsute on the prominent midrib and nerves, veins closely reticulated, 3| in. 

 long, 1|^^ in. broad, on petioles 3 lines long ; panicles in opposite axils, on a slender naked 

 pubescent pedunclo 1^ in. long, twice trichotomously branched, each branch bearing about 

 3 floAvers, on pedicels with small bractlets and 4-6 lines long; sepals obtusely oblong, 

 membranaceou;s, with ciliate margins, sparsely pilose, 85-4 lines long, 1-1^ line broad, 

 unequal, imbricate ; corolla 2 j m. long ; tube cylindrical, suddenly constricted below 

 the middle; segments dolabriform, rounded on the dexter side, simply convolute in the 

 bud ; stamens seated at the constriction of the tube ; anthers linear, narrow, somewhat 

 shortly bifurcate at the base ; disk urceolate, 5-sulcate, and denticulated on the margin, 

 concealing the 2 ovaries.

An erect shrub, different from the preceding species, with very straight, subfistular, 

 glabrous, opake branches, striate, rendered somewhat scabrous by many short, prominent, 

 obtuse lenticels, with 2 stipules on each side between the petioles; leaves oblong-ovate, 

 subcordate at the base, roundish towards the summit, and there constricted suddenly into 

 a short acumen, chartaceous, opake above, with immersed nerves and transversely reticu- 

 lated fine veins, paler beneath, pruinously opake (not pubescent), midrib and nerves pro- 

 minent, 3-5f in. long, lJ-2^ in. broad, on stout, recurving, glabrous petioles 3-5 lines 

 long ; panicle lateral, 3-5 in. long, on a deflected peduncle 6-18 lines long, divided at its 

 apex into 2 parallel floriferous branches, each bearing about 6 alternate flowers ; bracts 

 linear-oblong, reddish, submembranaceous, margins glabrous, 3 lines long; pedicels 3-6 

 lines long ; sepals oblong, obtuse, glabrous, membranaceous, imbricate, 4-6 lines long, 

 with an internal, subulate, bidentate scale ; corolla handsome, deep rose-colour ; tube 

 20 lines long, narrowly cylindrical for half its length, fleshy, pubescent inside, cam- 

 panular and glabrous above ; segments obliquely very inequilateral, with an acute 

 tooth near the sinister angle, dextrorsely convolute, 9 lines long and broad ; stamens
