1. S. cymbifolium, Dill. Dioecious; stems robust, 6' -18' long; 

 branches 4-6 in a fascicle, tumid, mostly obtuse ; stem-leaves spatulate, not 

 fibrillose ; branch-leaves imbricated, ovate, cucullate and entire at the apex ; 

 capsule with stomata in its wall. — Bogs, &c. ; common. — A large species, dis- 

 tinguished from its congeners by the sharp papillEe on the back of the leaf near 

 the apex, and by the striae on the walls of the cortical utricles of the branches.

4. S. I^escurii, Sulliv. (Muse. Bor.-Amer., No. 6.) Aspect same as 

 that of small fonns of No. 1 ; ramification and mode of growth loose ; branches

 lanceolate, the utricles fibrUlose ; branch-leaves ovate-lanceolate, imbricated ; 

 utricles ample, with a few large pores ; ducts nearly cuneiform-elliptic, approach- 

 ing the concave surface of the leaf; perichastial leaves ovate-subulate, undulate 

 on the convolute margins above, the utricles mostly not fibrillose ; capsule 

 scarcely emergent. — Margins of rivulets; Eaccoon Mountains, Alabama, ies- 

 quereux. 



6. S. IftUmile, Schimper. Csespitose; stems l'-2' high, with 3 layers 

 of cortical utricles ; branches crowded, spreading, 2-3 in a fascicle ; branch-

 Stems 2' - 3' long, thick, turgid, flaccid, with only one layer of cortical utricles, 

 mostly simple, rarely with a few scattered branches, not in fascicles ; leaves pale 

 greenish-white, narrowly margined, somewhat constricted at base, closely imbri-
