284 WILSON EXPEDITION TO CHINA 
The plant collected by Piasezkii in Shensi and referred by Maximowicz according 
to Hemsley in Jour. Linn. Soc. X XIII. 57 (1886) to X ylosma senticosum Hance is more 
probably Xylosma 1 , var. pub , since it is unlikely that a subtropical 
plant would be found so far north. Both agree in having pubescent branches, but 
the leaves in Hance's plant are described as only 6-8 lines long. 
Xylosma Dunnianum Léveillé in Fedde, Rep. Nov. Sp. IX. 455 (1911) apparently 
belongs to some other genus since he describes petals and says they are “‘twice as 
long as the sepals." 
'Two other species of Xylosma occur in Yunnan: 
Xylosma longifolium Clos in Ann. Sci. Nat. sér. 4, VIII. 231 (1857). — Hooker 
f., Fl. Brit. Ind. I. 194 (1872). 
Yunnan: Mengtze, alt. 1500 m., A. Henry (Nos. 9901, 9901* 9901"); Szemao, 
— alt. 1600 m., A. Henry, (No. 12635); Talang, alt. 1600 m., A. Henry (13334). 
Xylosma controversum Clos in Ann. Sci. Nat. sér. 4, VIII. 231 (1857). — Hooker, 
f., Fl. Brit. Ind. Y. 194 (1872). 
Yunnan: Szemao, alt. 1300-2000 m., A. Henry (Nos. 11884°, 12757).

Diels in Bot. Jahrb. XXIX, 478 (1900). — Bean in Kew Bull. Misc. 
Inform. X XII. 353 (1909). 
Western Szech’uan: Mupin, side of streams, alt. 600-1100 m., 
June and November 1908 (No. 1212, in part; tree 6-10 m. tall, 1—1.60 
m. girth, flowers white); Niu-tou-shan, west of Kuan Hsien, alt. 1600 
m., June 1908 (1212, in part; tree 6 m. tall, 30 cm. girth, flowers white) ; 
Hung-ya Hsien, side of streams, alt. 1000 m., September 1908 (No. 
1212, in part; tree 6-10 m. tall, 1-2 m. girth); without precise locality, 
ravines, 1300 m., July 1903 (Veitch Exped. No. 3227); Mt. Omei, 
June 1904 (Veitch Exped. No. 4752). Western Hupeh: without 
precise locality (Veitch Exped. No. 1104). 
This handsome tree is very rare in western Hupeh, but common in western 
Szech'uan, especially by the side of woodland streams up to 1200 m. altitude. 
Whilst not forming a tall or even large tree, the much-branched and flat head is 
wide-spreading; the bark is grey and usually smooth, but in very old trees it 
becomes furrowed and corrugated. The flowers are ivory-white and of much 
substance. 
A second species of this genus, Carrierea Dunniana Léveillé, is described in Fedde, 
Rep. Nov. Sp. IX. 459 (1911), but we have seen no specimens and the description 18 
too meagre. s
