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-lé 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, Icon. Ess. For. Jap. I. 83 t. 47, fig. 13-24 
(1900). AIl the early figures appear to us to belong to the Chinese plant, Photinia 
serrulata 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. :
