This small tree is abundant in the thickets and margins of woods, especially in 
the vicinity of streams throughout western Szech'uan from the neighborhood of 
Sung-pan in the north to Tachien-lu in the west and southwards through Yunnan. 
We have no specimens actually localized from Mupin, but have them from the 
northern, southern and western boundary of this petty state. We have not seen 
the type of Baillon's E. Davidiana, but the geographical distribution so strongly 
supports Solereder's evidence that there can be no doubt but Baillon's fragment 
is referable to the same species and to its numerous specimens before us. 
Hooker & Thomson describe the under surface of the leaves as “ pale,” but 
glaucescent gives a better idea of the appearance, which is due to a dense cover- 
ing of papillae. This glaucescent appearance of the under surface readily dis- 
tinguishes this species which, like E. Franchetii, is a small bushy tree, with thin 
branches and leaves assuming brilliant tints in the autumn, 
Our specimen of Henry's 10746 has all the leaves ovate, acuminate and broadly
