554 WILSON EXPEDITION TO CHINA 
Pieris villosa, var. pubescens Rehder & Wilson, n. comb. 
Pieris ovalifolia, var. pubescens Franchet in Nouv. Arch. Mus. Paris, sér. 2, 
X. 44 (Pl. David. II. 82) (1887). 
Western Szech’uan: west and near Wén-ch’uan Hsien, alt. 2000 
m., July 1908 (No. 3191; bush 1 m. tall, flowers white). 
This variety is chiefly distinguished from the type by its pubescent ovary. Our 
specimen differs from Franchet’s description in the glabrescent calyx; in the speci- 
mens of typical P. villosa the calyx is rather densely pubescent, but the ovary is 
glabrous; this separates Franchet’s variety from typical Pieris villosa. 
GAULTHERIA L. 
Gaultheria Veitchiana Craib in Gard. Chron. ser. 3, LII. 188 (1912). 
Gaultheria fragrantissima, var. hirsuta Franchet in Nouv. Arch. Mus. Paris, 
sér. 2, X. 44 (PI. David. II. 82) (non Clarke) (1887). 
Western Szech'uan: Mupin, thickets, alt. 2300-2800 m., June 
to August 1908 (No. 829; decumbent shrub, 0.3-1 m. tall, flowers 
white, fruit indigo blue); south-east of Tachien-lu, thickets, alt. 
2600 m., June 1908 (No. 829°); Ching-chi Hsien, Ta-hsiang-ling, alt. 
2600-3000 m., August 1908 (No. 829^; shrub 0.3-0.75 m. tall); west - 
of Kuan Hsien, summit of Niu-tou-shan, alt. 3300 m., June 20, 1908 
(No. 2712; shrub 20-30 cm. tall, flowers white); without precise 
locality, alt. 2000-3300 m., May 1904 (Veitch Exped. No. 3916, 
type). 
This species is widely distributed in western Szech’uan, growing on most moun- 
tain-sides, margins of woods and thickets. Usually the branches are prostrate Or 
nearly so, but occasionally it forms a bush 3 ft. tall. In No. 2712 all the flowers 
are globose in shape, but otherwise agree with those of the type. 
Veitchiana is a very charming little shrub with its evergreen leaves, white eres 
and indigo-blue fruits. It is in cultivation and is perfectly hardy in England.
