ULMACEAE. — CELTIS 271 



This species occurs in open country, in thickets and by the side of streams from 

 river-level up to 1600 m. altitude throughout western Hupeh and eastern Szech'uan, 

 but is nowhere common. It is a tree of medium size, growing from 10 to 15 m. 

 tall, with a trunk from 1 to 2 m. in girth. The bark is smooth and light gray and 

 the rather thick branches spread to form a broad flattened or rounded crown. 



A picture of this tree will be found under No. 625 of the collection of my photo- 

 graphs and in my Vegetation of Western China, No. 160. E. H. W.

Western Hupeh: Fang Hsien, thickets, alt. 1100 m., October 

 1907 (No. 593, type; tree 7-10 m. tall, girth 0.6-1.2 m., fruits black; 

 with ripe fruits); Wushan Hsien, thickets, alt. 1100 m., September 

 1907 (No. 442; 3 m. tall, fruits black; with almost ripe fruits. 

 Young plants are growing in the Arnold Arboretum). 



This species seems to be well characterized by its papillose leaves and by its 

 rather large bluish-black fruits, not unlike small cherries, and by its irregularly 

 pitted and gibbous stones. It may be most nearly related to C. jessoensi^ Koidzumi, 

 which has thinner, more closely serrate, mostly narrower and longer-pointed leaves,
