Doubtful Species. 
C. argentea A. DC. ? Gamble suggests it may be C. hystrix A. 
DC. A small tree in young fruit only. Leaves stiffly coria¬ 
ceous, oblong shortly blunt acuminate, base cuneate pale

wide; petioles -i in. long. Young fruit crowded in long spikes 
6 in. or more long. Spines numerous close-set narrowed
