A tall vigorous voluble shrub; stem and main branches glabrate, 

 browish-grey ; branches and branchlets slender, terete, patent-retrorsely 

 pubescent but tomentose in youngest ones, nodes mostly remote ; lenticels 

 disparsed, small, rounded to elliptical. Leaves opposite, petiolate, elliptico- 

 oblong, ovate-elliptical, oblong-ovate, or ovate, abruptly and shortly acuminate 

 with an obtuse or acutish tip, rounded to cordate at the base, entire and 

 minutely ciliated, membranaceous or chartaceo-membranaceous, deep-green 

 above, slightly paler beneath, 41-17 cm. long, 3-11 cm. wide, midrib and 

 veins pubescent and the hairs denser beneath, young leaves disparsed with 

 minute pubescent hairs ; veins erect-patent, connected before reaching the 

 margin ; about 6-8 on each side ; petiole much shorter than the blade, 

 9-22 mm. long, erect-patent or spreading or reflexed, pubescent. Cyme 

 on branchlets of this year, axillary, umbellate, shorter than leaves, peduncled,. 

 2-5-flowered; peduncle straight, short, solitary, erect-patent, or patent, 

 rarely one-branched, thinly pubescent as is the pedicel, 3-14 mm. long, 

 pedicels straight, narrowly terete, thicker under the flower, viridescent, erect or 

 erect-patent, much longer than the peduncle, 15-28 mm. long ; bracts small, 

 scaly, about 3-5, placed at the base of pedicels, unequal in size, lato- 

 subulate, lato-ovate, ovato-oblong, oblong, lato-linear, linear, or sometimes 

 spathulato-linear, usually obtuse, about 1-4 mm. long, pubescent towards the 

 margin and ciliated. Flower large, white, fragrant, 3J-6 cm. across, often 

 with black juice filling the corolla-tube. Calyx 5-sepaled, rounded-obtuse 

 at base, G-13 mm. long, glabrous but minutely ciliated, green ; sepals 

 imbricated, somewhat unequal, erect, narrowly ovate, ovato-lanceolate, or 

 narrowly oblong, obtuse or acutish, entire, thickish below, midrib more or 

 less prominent dorsally, veinlets irregularly anastomosing, with free extreme 

 venules. Corolla hypocraterimorphous, subcarnose ; tube exserted, cylindrical, 

 slightly swollen at the base, 11-13 mm. long, 6-7 mm. across, glabrous and 

 longitudinally 5-sulcate below externally, marked with longitudinally pilose 

 lines 5 above and 10 below internally ; lobes 5, arcuato-patent, longer 

 than the tube, angustato-lanceolate to ovato-lanceolate, slightly falcate, 

 obtuse or acutish, entire and laxly ciliolate, minutely auriculate on one side 

 at the base, sinistrorsely convolute in proefloration, 17-30 mm. long, 6-9 mm. 

 wide, subtrinerved below, midrib slender, veinlets delicate and irregularly 

 anastomosing. Genitals included, glabrous, about 7-8 mm. long. Staminal 

 corona 5, narrowly deltoid, erect, flattened and longitudinally subangulate 

 in centre above dorsally, almost entirely adnate to the column (connate 

 filaments) and shorter than it and the obtuse tips slightly free, black when
