The var. /3 was found on the Clova Mountains, Scotland, by 
Sir W. J. Hooker and Dr. Greville, in 1824, where, Dr. G. says, 
“ It is very common on the flat marshy table-land. In places 
from which the water was drained it was only 9-10 inches in 
height with shorter and closer spikes.” The large size of the 
typical form noticed by Wahlenberg, Fries tells me, is exceptional. 
Drejer does not include G. aguatilis in his ‘ Revisio but I have 
no hesitation in referring his O. stans to the var. /3, and Fries re¬ 
fers C. anguillata to O. aguatilis.
