[ ] the original morphology
1stout woody climbers. Branches with lenticels inconspicuous, with latex, except for corolla, glabrous. Leaves opposite; petiole 1-1.5cm, slightly hairy; leaf blade elliptic or ovate-elliptic,5-8cm long,1.5-3cm wide, apex acuminate, base acute. Inflorescence racemose, terminal and axillary, flowers small dense, red; calyx5 crack greatly, the inner surface of basal glands do not or lack, lobes lanceolate; corolla white or pink, urn-shaped, lobes in the bud invagination; stamens 5, inserted on corolla tube base, anthers sagittate, flower filaments short; disk annular; ovary puberulent, styles short, stigma conical. Follicles base dilated, apex gradually grow to Reiz beaklike. Seed up to 2cm; hair is about 4cm long silky white. Florescence 3-6 month, month of fruit period 7-12.
2and Du Zhongteng 's difference lies in: the blades oval shape is elliptic, abaxially black papillary glands. Follicles twin or sometimes: a rudimentary; hair length is about 1.5cm. Florescence 4-11 month, fruit period in August to February of next year.
The 3and two kinds of difference: all lines except for corolla, are densely ferruginous pilose. Hair whorls, ca.3cm. Florescence 4-6 month, fruit period in July to June of next year.

Character.
Character identification in Du Nakato Kihide a roll or groove, thickness 1-2.5mm. Strip on the outer surface of the cork, grey brown or pale yellow, with wrinkles and a horizontal lenticels, yellow-white, scraping the cork was red brown, relatively flat.
