BENNETT: CAREX AQUATILIS IN LAKE LANCASHIRE. 79 
certainty is impossible in this difficult section. But looking at the 
specimen now, I see no serious objection to its being a sa/ina form. 
This plant is very different to the specimens named ‘C. rigida 
inferalpina’ by Dr. Almquist, which are clearly rigida forms (not 
salin 
I have a specimen from ‘Lough Ree, Co. Westmeath, R. M. 
Barrington, 1885," which was named in 1888 ‘ Carex turfosa 
Fr, f. elongata,’ by Dr. Lange ; elect this by the side of Dr. White’s 
Methven specimens, I can see very little difference ; in the Perth 
plant the glumes of the male flower are fringed with a pale colour, 
while those of the Ree plant are only obscurely so. 
In my large series of British aguatilis for all parts of its known 
area there are many differences, but they shade off one into the 
other, and I cannot see how we can make out any sub- -specific 
differences to the Scandinavian forms (of which also I possess a good 
series) ; my Asiatic and American material is not extensive enough 
\o judge by.
