ROSACEAE. — PHOTINIA 185 



Kiangsi: Kuling, thickets, alt. 1300 m. July 1907 (No. 1676; bush 

 2 m. tall). Western Hupeh: south of Ichang, alt. 300-1000 m., 

 May and October 1907 (No. 449; bush or tree 3-10 m. tall, flowers 

 white, fruits scarlet); without precise locality, April and October 

 1900 (Veitch Exped. Nos. 167, 391,462 a.). Eastern Szech'uan: 

 South Wushan, A. Henry (No. 1490). Western Szech'uan: Mt. 

 Omei, May 1904 (Veitch Exped. No. 4873); without precise locality, 

 A. von Rosthorn (No. 1697). Chekiang: vicinity of Ningpo, 1908, 

 D. Macgregor. Yunnan: Mi-le district, A. Henry (No. 9899); 

 Mengtze, A. Henry (Nos. 9899 b, 9795); Linan, A. Henry (No. 

 10576). 



A very common evergreen bush or small tree throughout the warm-temperate 

 parts of China, varying considerably in the size and shape of its leaves. The 

 only figure we have found of the true Photinia glabra Maximowicz {Crataegus 

 glabra Thunberg) is published by Shirasawa, Icori. Ess. For. Jap. 1. 83 t. 47, fig. 13-24 

 (1900). All the early figures appear to us to belong to the Chinese plant, Photinia 

 serrulaia Lindley. 



It is possible that Henry's Yunnan specimens, which are all in fruit, belong to 

 Photinia Lindleyana Wight & Arnott, but the distinctions between these two 

 species are not very obvious.
