 Ailanthus glandulosa^ var. sutchuenensis Rehder in Mitt Deutsch, Dendr, Ges. 



XXI. 187 (1912). 



Western Hupeh: Ichang, common up to 800 m. alt., June and 

 September 1907 (No. 2034; tree 13-25 m. tall, girth 1-3 m.); same 

 locality, May and October 1900 (Veitch Exped. No. 663); without 

 locality, A. Henry (No. 3886). 



The more shining and glabrous shoots and larger fruit distinguish this variety 

 from the type; the leaves, too, are less ciliate on the margins, but this character 

 varies. This tree is common in the neighborhood of Ichang where it is known as 

 the " Ch'ao ch'un shu " (stinking Cedrela tree). 



Ailanthus Vilmoriniana Dode in Rev, HorL 1904, 444, fig. 184; in 

 Bull Soc, Dendr. France, 1907, 190, fig. c. 



Ailanthus glandulosa^ var. spinosa Vilmorin & Bois, Frut Vilmorin, 31, fig. (1904) 



Western Hupeh: Fang Hsien, roadsides, alt. 1000-1100 m., 

 May, July and September 1907 (No. 388; tree 6-16 m. tall). 



This tree is common in the dry, warm river-valleys of Szech'uan and less so in 



western Hupeh. Usually it is a tree of moderate size, but specimens forty metres 



tall occur occasionally. The spiny shoots and petioles is a juvenile character and 



disappears when the trees attain maturity. The pubescent leaves and larger fruit 



distinguish this species from A. cacodendrcm, Schinz & Thellung, In Fang Hsien 



this tree is sometimes planted and the leaves employed for feeding the Hawk-moth 



{Attacus cynthia) which produces a kind of silk. 



Pictures of this tree will be found under Nos. 048 and 0128 of the collection of 

 Wilson's photographs.
