24:4 Select Plants for Industrial Culture 



Pachyma Hoelen, Fries. 



China. This large Truffle occurs particularly in the province of 

 Souchong. Flavor most agreeable. Naturalization elsewhere to be 

 tried. 



Pachyrrhizus angulatus, Richard. 



From Central America rendered spontaneous in many tropical 

 countries. A climber, the horizontal starchy roots of which attain a 

 length of 8 feet and a thickness of many inches. Dr. Peckolt 

 records tubers of 70 Ibs. weight. They keep, in dry ground, growing 

 for five years, but such are then available only for starch, whereas 

 annual tubers are the most palatable and yield 6 to 7 per cent, of 

 starch. From the stems a tough fibre is obtained. The plant 

 proved hardy at Sydney; it requires rich soil.

China and Japan. A thorny tree, which could be utilized for 

 hedging. 



Paliurus Spina Christi, Miller. (P. acidmtus, Lambert.)

 habit, attaining a height of 30 feet. Panicles sometimes a foot and 

 a half long. Evidently desirable for naturalization.
