This species is very abundant around Kuling and fairly common in western 

 Hupeh. The leaf characters are variable and so is the degree of hairiness of the 

 shoots. Stipitate glands are usually to be found scattered through the villose 

 tomentum on the petioles, young shoots, and occasionally on the under surface 

 of the leaves, but vary greatly in number and are often lacking. The fruits are 

 nearly globose, about 8 mm. in diameter, sessile or subsessile, crowded into a short 

 spicate raceme, villose and at the summit glabrescent. The seeds, when ripe, are 

 jet black, as they are in every other species of the genus.

Kiangsi: Kuling, thickets, alt. 1300 m., July 29, 1907 (No. i555; 

 bush 2-2.5 m. tall). Eastern Szech'uan: Nanch'uan, "Lao- 

 titzu," September 19, 1891, A. von Rosthorn (No. 966). 



The glandular character on which Hemsley relied in establishing his species 

 cannot be depended on, as it is also found in the typical C. sinensis Hemsley. A 

 comparison of Hemsley's figures shows the floral structure to be identical in his two 

 species. The glabrous character of the ovary and calyx seems to us the only dis- 

 tinguishing feature of var. glandulifera, and the only one by which we can sep- 

 arate it from the type. The fruit is similar in size and shape to that of the type, 

 but glabrous and usually subsessile.
