 shrub or small tree about 18 feet high, found in 

 semiarid situations. It has short spines, pinnate 

 leaves, and pale cream-colored flowers in headlike 

 spikes. The Mexican name is tanasa. 



75262. Sapium sebeferum Roxb. (L.) Euphorbi- 

 aceae. Chinese tallowtree. 



No. 24198. Brownsville, Tex.. October 28, 

 1927. An attractive tree, native to China, 

 which is long-lived, and at maturity has a height 

 of 40 to 50 feet and a diameter of 5 to 6 feet. The 

 3-celled, flattened-ovoid fruits are about three- 

 fifths of an inch in diameter. When ripe they 

 are blackish brown and woody in appearance; 

 in China these are either gathered by hand or 

 knocked down by poles. After being collected, 

 the fruits are spread in the sun, where they 

 open, and each liberates three elliptical seeds 

 covered with a white substance which is a fat or 

 tallow. After this substance has been removed 

 by steaming and rubbing through a bamboo 

 sieve, the fat is collected and melted, molded into 

 cakes, and sold as the Pi yu of commerce. After 

 the fat is removed the seeds are crushed, and the 

 oil expressed from them is called Ting yu. In 

 China the oil and tallow are used in the manu- 

 facture of candles, and these products are also 

 exported in quantity to Europe, where they are 

 used in the manufacture of soap. The tree is 

 occasionally grown as a shade tree in the Gulf 

 and South Atlantic States.
