of pale waxy color ; very sour. Occurring in mountain ravines and on 

 pebbly creek bottoms, sometimes to the exclusion of almost everything 

 else. Of value as an ornamental park tree, suited especially for the 

 cooler and drier sections of the United States. Collected at an altitude 

 of 7,000 feet above the sea. Chinese name Suan tz'u, meaning ' sour 

 thorn.' " 

 40716 and 40717. Rhus spp. Anacardiacese. Sumac. 



40716. Rhus javanica L. 



"(No. 2241a. Near Yuyinchen, between Liangtang and Hweihsien, 

 Kansu, China. September 25, 1914.) A sumac, found on stony 

 mountain slopes, in ravines, and in wild places, becoming a tall shrub 

 or small tree. Leaves large, light green, pubescent, winged. Fruits 

 borne in large spikes; berries coated with a sticky whitish wax which 

 burns readily. The Chinese do not seem to utilize this wax in any 

 way. Of value as an ornamental park shrub for the mild-wintered 

 sections of the United States." 



40717. Rhus potanini Maxim. 



"(No. 2242a. Mountains near Kwanyintang, between Paoki and 

 Fenghsien. Shensi. China. September 15, 1914.) A sumac with 

 medium-sized, glossy green leaves and reddish petioles, becoming a 

 tall shrub or even a tree up to 60 feet high. Assumes most brilliant 

 colors in fall. Produces many spikes of reddish bronze-colored 

 berries, which persist on the trees for a long time. On this sumac 

 a gall insect makes its home, producing large inflated galls, which 

 the Chinese utilize much for dyeing black. The foreigners, however, 

 found that they contain a great percentage of tannin, vast quantities 

 being exported from Hankow, especially under the name of Chinese 

 gallnuts. This sumac possibly might be cultivated on cheap lands 

 in the Southern States for its gall production. It is not very par- 

 ticular as to soil requirements, but it loves good drainage. Care 

 should be taken, however, to keep it well under control, as it has 

 decidedly weedy tendencies. Chinese name, Wu pei tzu shu, meaning 

 ' five-folded seed tree.' " 



40718. Hovenia dtjlcis Thunb. Rhamnaceae. 



"(No. 2243a. Siku, Kansu, China. November 12. 1914.) A tree 

 growing to he 40 to GO feet high, cultivated in gardens for its pecidiar 

 looking swollen fruit stalks, which are very sweet and much beloved by 

 the Chinese as a delicacy. They are believed to undo the effects of 

 having had too much wine at a dinner or a feast. This tree is not 

 particularly ornamental, with its elmlike leaves and its rather open 

 growth. It might be cultivated, however, on a small scale in the Southern 

 States, so as to supply the large Chinese colonies in America with one 

 of their favorite sweetmeats. These fruit pedicels can be eaten fresh 

 or dried; in the latter way they can he shipped over long distances. 

 Chinese name Kua tsao, meaning ' warming jujube.' '

 "(No. 2244a. Near Chaolienli, near Fenghsien, Shensi. China. Sep- 

 tember 17, 1914.) A medium-sized tree, with handsome pinnated leaves, 

 bearing large umbels of whitish flowers, followed by big hunches of fruits. 

 which, at first green, later on turn to a dark-red color. Found in some-
