Sect 1. ORTHOPETALUM Koehne. 
Cotoneaster disticha Lange in Bot. Tidsskr. XIII. 19 (1882). — 
Schneider, IU. Handb. Laubholzk. Y. 744, fig. 418 c-f, 419 a-b (1906). 
Cotoneaster rotundifolia Baker in Refug. Bot. I. t. 54 (non Wallich) (1869). — 
Hemsley in Bot. Mag. CXXXI. t. 8010 (pro parte, ram. fructiferus tan- 
tum) (1905). 
The type of this species has not been reported from China. 
Cotoneaster disticha, var. tongolensis Schneider, Ill. Handb. Laub- 
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.
