Hab. Plentiful in moist places in various parts of the south, west, and north of England, 
as well as in Scotland and Ireland. — So abundant is it at Allan’s Ford, near Durham, that 
Mr. Thornhill informs me he could, in a very short space of time, have loaded a cart with 
it. (Mr. Lyell finds it with anthers in October, and Dillenius observes that the capsules 
are produced in the month of March.) 
Plant growing in densely crowded patches, often covering a space of ground of several feet in 
diameter, and rendered very conspicuous at a distance, from its extremely pale-green color. 
Root scarcely any, except a few pellucid, short, and simple fibres, which may now and 
then be seen towards the base of the plant.
