 cluster, terete, 1 inch thick at the base, snbglaucous and sharply 

 spinescent, the greenish tissue sweetish but without odor; 

 roots from all sides of the tubercles which form clusters of 

 individuals from I to 5 inclies in diameter; these indi- 

 viduals are yellowish, subglobose or truncate at the base and 

 conically tapering; branches repeatedly branched, long, drooping, 

 sal>twining, terete, green, tough; leaves diverse in size, tbe
