Woods, and banks in heathy places, abundant. Fr. Apr. — Stems red-

Moist shady banks and on trunks of trees, especially such as are in a 

 state of decay. Fr. Nov. — A variable plant, certainly. In mountainous 

 wet situations, the var. named Stokesii occurs, with closely set bipinnate 

 branches ; and in wet hollows, the state called Swartzii, which is well 

 represented in the magnified figure of Turn. Muse. Hib. t. 14./. 2. b. 

 and which, as Mr. Wilson observes, is chiefly to be distinguished by its 

 shorter capsule and darker colour.
