 tum) (1905).

Cotoneaster disticha, var. tongolensis Schneider, III. Handh. Lauh- 

 holzk. I. 745, fig. 419 d (1906). 



Western Szech'uan; uplands around Tachien-lu, alt. 2600-3000 

 m., June 1908 (No. 2186; decumbent bush, 1 m. tall). 



Our specimen is from the same region as the one described by Schneider, and 

 agrees well with his description, but is rather less hairy. Schneider expresses doubt 

 whether his specimen should be regarded as a variety of Cotoneaster disticha or of 

 Cotoneaster Simonsii Baker. Our specimen is certainly not referable to Cotoneaster 

 Simonsii and shows a closer relation to Cotoneaster disticha.
