Western Hupeh: Fang Hsien, thickets, alt. 1800 m., October 

 1910 (No. 4459; climber 5-7 m., fruit smooth, ovoid) ; without precise

This species is easily distinguished from all related species by the glaucous under 

 side of the leaves, which are perfectly glabrous with the exception of tufts of hairs 

 in the axils of the veins. The pistillate flowers are usually solitary, while the 

 staminate are borne in 3-5-flowered cymes. Wilson's No. 1068 differs somewhat 

 in its narrow, oblong to oblong-oblanceolate leaves, broadly cuneate at the base 

 and 8-9 cm. long and 2.5-3 cm, broad; Henry's No. 5838* has the leaves also 

 broadly cuneate at the base, but more elliptic in outline and up to 4 cm. broad. 

 Wilson's No. 3269, referred by Dunn to this species, belongs to the following 

 species.
