those of other provinces have. It is also universally known 
in Europe, yet a full and accurate description with figures 
seems still to be wanting. Its parts of fructification appear to —

yet met with, on that account I have been obliged to give it a

known to me with it; for they clearly make but one gens. 
Ihave at this instant both the living plants before me in bigh 
perfection, and after repeated examination, can safely say
