184 WILSON EXPEDITION TO CHINA 



OSTEOMELES Lindley. 



Determined by E. H. Wilson. 



Osteomeles Schwerinae Schneider, III. Handb. Lauhholzk. I. 762, 

 fig. 430 m, 431 o-r (1906); in Fedde, Rep. Nov. Sp. III. 222 (1906). 



Osteomeles anthyllidijolia Franchet, PI. Delavay. 227 (non Lindley) (1890). — 

 Hooker f. in Bot. Mag. CXX. t. 7354 (1894). 



Yunnan: Mengtze, alt. 1500-1800 m., A. Henry (Nos. 9315, 

 9315^ type). Western Szech'uan: banks of Yangtsze river near 

 city of Sui Fu, alt. 360 m., April 1908 (No. 2371; bush 1-1.60 m. tall, 

 flowers white): Min valley, around Mao-chou, alt. 1300-2000 m., 

 May and September 1908 (No. 1016; bush 1-3 m. tall, flowers white, 

 fruits black with purple bloom) ; cliffs on Yangtsze near Sui Fu, April 

 1904 (Veitch Exped. No. 3518); Tung valley, July 1903 (Veitch Exped. 

 No. 3518"). 



This western Chinese species is readily distinguished from the insular Osteo- 

 meles anlhyllidifolia Lindley by its smaller and narrower leaves, smaller flowers, 

 glabrescent calyx and glabrous fruit. Osteomeles suhrotunda K. Koch in Ann. 

 Mus. Lugd.-Bat. I. 250, figured in Hooker's Icon. XXVII. t. 2644, appears to be 

 more closely related to 0. anthyllidifolia Lindley than to 0. Schwerinae Schneider. 



In our No. 1016 the calyx is glabrous or nearly so and the sepals shorter than 

 in the type. No. 3518 Veitch Exped. has much larger flowers than the type and 

 they are commonly soUtary. 



In Szech'uan this plant is restricted to the river-valley where a dry, hot climate 

 obtains.
