Deciduous scandent shrub. Brandies slender, dextorse, laxly ramulose, 

 avellaneous-.griseous, glabrate, but disparsedly adpressed-hirsute or densely 

 tomentoso-hirsute in young shoot, distributed with small lenticels; scars of 

 leaves slightly prominent and orbicular, with a flat face; leaf-bud naked 

 (without bud-scales), tomentose with isabel-coloured hairs. Leaves alternate, 

 long-petiolate, exstipulate, ovate or elliptical-ovate, cordate at base, acumi- 

 nate, coarsely repand-dentate with apiculate tip, disparsedly piloso-hirsute 

 on both surfaces (hairs denser beneath), 5-12 cm. long, 3-9 cm. broad, 

 membranaceous, green above, paler beneath ; midrib prominent beneath ; 

 lateral veins 5-6 on each side ; erect-patent, hardly arcuate, reaching the tip 

 of teeth of the margin ; main veinlet.s transverse between lateral veins, the 

 small veinlets delicate and numerously anastomosing; petiole slender, at- 

 taining about 8 cm. long, disparsedly adpressed-hirsute. Panicle in the axil 

 of leaves and fallen leaves, laxly ramose into slender filiform pedicels 

 which are much longer than flowers, cernuo-pendulous, 2-G-fiowered, attaiuing 

 about 8cm. in length, disparsedly adpressed-pilose. Flower (staminate) 

 regular, 9-12 mm. across. Calyx much smaller than corolla, deeply 5- 

 parted, 3 mm. or little more across, patent, carnosulate, green, densely 

 covered with antrorsely adpressed fulvous hirsute hairs externally, glabrous 

 internally; lobes deltoid-ovate, obtuse. Corolla car nosulata, viridescent, 

 5-petaled, valvate in bud, coherent into a broad campanulate glabrous 

 tube at the base ; lobes patent, oblong-lanceolate, attenuatedly acuminate 

 and uncinulato-reflexed at the apex, G|-7 mm. long, 28-3 mm. wide, entire,
