(with us) perhaps with the exception of E. hyperborea — are so 
mixed up with transitional forms that I think it most practical 
to unite them into one species, EF. euofficinalis, with 3 sub- 
species or small-species, viz. a brevipila, ? stricta and y borealis. 
Of the other ,species" E. minima and E. latifolia should be 
united, as they pass insensibly into each other; E. curta is com- 
paratively well separated from the rest (but gives rise to forms, 
transitional: to E. brevipila and E. stricta by hybridization), and 
E. micrantha is generally well distinguished, but passes into 
E. scotica, which again forms a transition to E. minima, and 
perhaps is not distinguishable with any certainty from E. minima 
v. palustris.
