SAXIFRAGACEAE. — RIBES 153 
Ribes humile Janczewski. See p. 45. 
Western Szech’uan: uplands around Sungpan, alt. 3700-4300 
m., August 1910 (No. 4504: bush 1-1.50 m., fruits black). 
I refer this black-fruited specimen not without hesitation to R. humile; in the 
type-specimen the fruits are described as orange on the label, but the specimen 
was collected in June and the fruits are apparently immature. In size, shape, 
serration and the perfect glabrousness of the leaves and in the usually solitary very 
short-stalked fruits No. 4504 agrees exactly with the type specimen of R. humile. 
Possibly R. humile is only a variety of R. Vilmorinii. 
Ribes tenue Janczewski. See p. 45. 
Western Szech'uan: Pan-lan-shan, west of Kuan Hsien, wood- 
lands, alt. 2700-3000 m., August 1910 (No. 4033; bush 2-2.5 m., fruits 
red).
