After repeated examination of numerous forms of J. Hutchinsie, J am 
compelled to conclude that they constitute but a single very variable 
species. The most striking varieties are those above described. Its dis- 
tribution confronts us with a problem not easy of solution. In various 
localities along the western coasts of England, Wales, Scotland and 
Ireland it grows in some abundance, and fruits freely. Elsewhere in 
Europe it has not yet been met with ; but what we regard varieties of the 
same species exist in the warmer parts of North America, and in regions 
adjacent to the equator all round the globe. The question then arises
