Western Szech'uan: Wa-shan, woodlands, alt. 1300-2000 m., 

 July and October 1908 (Nos. 1164, S, and fruit, type, 3570); Monkong 

 Ting, roadside thickets, alt. 2000-2600 m., June 19, 1908 (No. 3569, 

 ^); Mt. Omei, September 1904 (Veitch Exped. No. 4772, fruit). 



This is a very distinct species characterized by its large leaflets, pyramidal in- 

 florescence, pentamerous flowers, reddish, tuberculate, non-beaked fruit and 1- 

 seeded carpels. It is apparently most closely allied to E. sutchuenensis Dode, 

 which according to his description differs in the leaflets which are pale glaucous on 

 the underside with tufts of villose hairs in the axils of the principal veins, and in 

 the inflorescence which is furnished with small leafy bracts. 



This new species is named for the late E. Colborne Baber, of the British Con- 

 sular Service in China, the first foreigner to make the ascent of Mount Wa and 

 Mount Omei, to whom science and literature are both indebted for a most graphic 

 and accurate description of these mountains and the adjacent regions. 



Here may be added a note on three other Chinese species of this section, not 

 collected during the Arnold Arboretum Expeditions.
