This is a very common tree in the woodlands of western Hupeh where it grows 

 to a larger size than any other species. Like its allies it has smooth gray bark, 

 spreading branches and brittle wood, and is known colloquially as the Ch'ou-la- 

 shu (Stinking Ash tree). It is also called P'ao-la-tzu, a name signifying that its 

 fruit is worthless as a drug in contradistinction to that of E. officinalis Dode. 



Dode describes the leaves as " subtus albido-glauca," but on our specimens they 

 are merely pale green or pallid on the under surface. Otherwise our material agrees 

 fairly with the short description. The leaflets are sometimes narrowed at the base 

 and have usually spreading hairs on the underside of the midrib and secondary 

 veins. The large flat or slightly rounded corymbs, the smaller flowers and the 

 axillary tufts of hair between the veins on the underside of the leaflets readily 

 distinguish this species from the closely allied E. Henryi Dode. 



A picture of this tree will be found under No. 583 of the collection of Wilson's 

 photographs and also in his Vegetation of Western China, No. 216.
