112 WILSON EXPEDITION TO CHINA 



Viburnum foetidum, var. rectangulum (Graebner) Rehder in Sar- 

 gent, Trees and Shrubs, 11. 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: Ruling, thickets, abundant, alt. 1200 m., July 31, 1907 

 (No. 171 1). 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. 1025*, 1120); Wa-ssu country, Wen-chuan 

 Hsien, thickets, alt. 1800-2500 m., June 1908 and October 1910 (Nos. 

 1813, 4196).
