varying in proportion in different soils, but readily recognized by 
their more or less convex, rugged and almost wrinkled surface, ending 
in a small curved point. According to. Bentham and Hooker this 
is probably a form of S. caprea.

present, under different circumstances, so much diversity of character, that 
many of the most eminent botanists are undecided as to the true limits of their 
variation ; many forms being considered mere varieties resulting from difference 
of soil and situation, by one party, while by another, they are exalted to the rank 
of species. Z. B. F.
