Fraxinus chinensis is one of the most polymorphous species of the genus. In 

 Bot. Jahrb. XL. 216 (1902) I have enumerated five varieties, to which I add now 

 var. rhynchophylla Hemsley after having studied the abundant material of the 

 Herbarium of the Arnold Arboretum. 



Fraxinus obovata Blume in Mus.-Ludg. Bot. I. 311 (1849-51) with scabrid 

 pubescence on both sides of the leaflets is said to have been introduced from 

 China to Japan. The flowers of this species are unknown and the original plant 

 is not found in any collection and has never been seen since Blume described it. 



Pictures of F. chinensis will be found under Nos. 306 and 310 of the collec- 

 tion of Wilson's photographs and also in his Vegetation of Western China, Nos. 

 226, 227. 



Here may be added a reference to another variety not collected during the 

 Arnold Arboretum Expeditions. 



Fraxinus chinensis, var. acuminata Lingclsheim in Bot. Jahrb. XL. 216 (1907). 



Western China: Yalung Valley, alt. 3000-3300 m., June 1904 (Veitch Exped. 

 No. 4088; tree 7-14 m. tall).
