112 WILSON EXPEDITION TO CHINA 
Viburnum foetidum, var. rectangulum (Graebner) Rehder in Sar- 
gent, Trees and Shrubs, II. 114 (1908). 
Western Szech’uan: Mupin, thickets, alt. 900-1200 m., June 
and October 1908 (No. 1131). Western Hupeh: Patung Hsien, 
thickets, alt. 1200 m., July 1907 (No. 1833). 
Wilson’s specimens differ from the type of this variety in the broader generally 
elliptic leaves, but agree with it in the peculiar mode of growth, the thin texture 
and the nearly glabrous veins of the leaves. 
Viburnum theiferum Rehder in Sargent, Trees and Shrubs, II. 43, 
t. 120 (1907); in Fedde, Rep. Sp. Nov. IX. 183 (1911). 
Kiangsi: Kuling, thickets, abundant, alt. 1200 m., July 31, 1907 
(No. 1711). Western Hupeh: north and south of Ichang, thickets, 
abundant, alt. 1200-2100 m., May and September 1907 (No. 218); 
Chang-lo-Hsien, thickets, alt. 1500-2100 m., September 1907 (No. 
236). 
Viburnum corylifolium Hooker f. & Thomson in Jour. Linn. Soc. II. 
174 (1858). 
Western Hupeh: Chang-yang Hsien, thickets, alt. 1500 m., May 
1907 (No. 447, as to the flowers). 
Wilson's No. 447 agrees well with Henry's No. 11362 from Yunnan which I 
have referred to this species. V. corylifolium is closely related to V. dilatatum 
Thunberg and may perhaps be considered a variety of it; it is chiefly distinguished 
by the long hispid pubescence of the petioles, inflorescence and young branchlets. 
It seems doubtful whether V. dilatatum occurs in western China, and the only 
Chinese specimen I have seen is from the province of Chekiang, collected near 
Ningpo by D. Macgregor (Herb. Arnold Arboretum); Wilson’s No. 944 which I 
referred formerly (Sargent Trees and Shrubs, II. 114) to that species probably be- 
longs to V. brevipes Rehder. 
Viburnum hirtulum Rehder in Sargent, Trees and Shrubs, II. 115 
(1908); in Fedde, Rep. Sp. Nov. IX. 184 (1911). 
Kiangsi: Kuling, thickets, 900-1200 m., July 28 and August 1, 
1907 (Nos. 1709, 1712, immature fruit). 
I refer Wilson's Nos. 1709 and 1712 with some hesitation to this species, the 
leaves are less pubescent, nearly glabrous above and less coriaceous than in the 
type, but the material is too incomplete to place the specimens definitively. 
Viburnum Wilsonii Rehder in Sargent, Trees and Shrubs, II. 115 
(1908); in Fedde, Rep. Sp. Nov. IX. 184 (1911). 
Western Szech'uan: Mupin, thickets, alt. 1500-1800 m., June 
and October 1908 (Nos. ro25*, 1120); Wa-ssu country, Wén-chuan 
Hsien, thickets, alt. 1800-2500 m., June 1908 and October 1910 (Nos. 
1813, 4196).
