384 WILSON EXPEDITION TO CHINA 



Western Szech'uan: west and near Wen-ch'uan Hsien, alt. 

 1800-2400 m., June and October 1908 (No. 1029, in part, t^q^e; flowers 

 buff-yellow, fruit russet); same locality, alt. 1200-2100 m., June 1908 

 (No. 888, in part; flowers buff -yellow) ; Wa-shan, thickets, alt. 1800- 

 2400 m., July 1908 (No. 1029, in part) ; same locality, alt. 1500-1800 m., 

 June 1908 (Nos. 888, in part, 891, in part); Wa-wu-shan, Yung-ching 

 Hsien, alt. 1200-2100 m., September 14, 1908 (No. 888, in part; fruit 

 glaucescent, ovoid); same locality, September 14, 1908 (No. 891, in 

 part; fruit ovoid to globose, russet, clustered) ; southeast of Tachien-lu, 

 alt. 2000 m., July and October 1908 (No. 1029=^; flowers buff-yellow, 

 fruit russet); Mt. Omei, July 1904 (Veitch Exped. No. 4765); without 

 precise locality (Veitch Exped. No. 3275). 



This species is closely related to A. callosa Lindley, which is easily distinguished, 

 however, by the more elliptic or oblong leaves usually broadly cuneate at 

 the base, with fewer usually 5-7 pairs of lateral veins and with less prominent 

 veinlets on the under surface, by the glabrous sepals and inflorescence, the white 

 flowers and by the smaller brown pith of the branches. The flowering specimens 

 of No. 888 differ somewhat from the other specimens in their narrower and longer, 

 oblong-ovate, long-acuminate and distinctly setosely serrulate leaves. The fruit of 

 No. 888 is described by Wilson as glaucescent, while the fruits of the other specimens 

 are described as russet. Henry's No. 10780 referred by Dunn to his A. callosa i. 

 D. does not seem to belong here according to the specimens in the herbarium of 

 the Arnold Arboretum, and represents probably an undescribed species related to 

 A. chinensis Planchon and A. rudis Dunn. 



Here may be added a note on a closely related species not collected during the 

 Arnold Arboretum Expeditions.

Western Hupeh: north and south of Ichang, rare, June 1901 (Veitch Exped. 

 No. 2204). Eastern Szech'uan: without precise locality, A. Henry (No. 7135). 



Finet & Gagnepain as well as Dunn consider this a variety of A. callosa Lindley, 

 but it is easily distinguished from that species by the distinctly ovate shape of the 

 leaves rounded or subcordate at the base and glaucous below, and by the short- 

 stalked usually solitary staminate flowers with tomentulose sepals. It has the 

 appearance of a perfectly distinct species. Actinidia sabiaefolia Dunn is very 

 near, but differs in the smaller crenate-serrate leaves acute or obtusish at the apex 

 and in the glabrous sepals.
