Carea hispida was discovered about a hundred years ago by 
Desfontaines, on the coast of Barbary, and named by him C. ech- 
inata. As this name had been previously given, by Ehrhart, to 
another species since named C. stellulata by Goodenough, Willde- 
now changed it to C. hispida, and he has been generally followed 
by caricologists, with the exception of Dr. Boott. . hispida isa 
agreeing with the European plant, but at full maturity is inflated 
at top and divergent. Willdenow’s character was taken from im- 
mature specimens, as he allows. The only roughness of the per- 
igynia mentioned by him is ‘capsulis marginatis hispidulis” 
which exactly describes the Arizona specimens. The affinity of 
. hispida is, according to Drejer, with C. glauca, Scop., C. tri- 
nervis, Desgl., and C. setigera, Don; while Dr. Boott sees a closer 
resemblance to his C. laciniata. :
