stems short, often bearing long slender branches reaching as

40. B. Schleicheri, Schwaegr. Closely resembles the last 

 species, differing essentially in the great size of the plants, the 

 leaves twice or thrice larger, bright or yellowish green, more 

 concave, not carinate, with margin narrower, the borders nearly

Var. angUStatum, Schimp. Plants shorter, slender, sim-

Var. latifolium, Schimp. 1. c. Tufts soft, inflated, green ; 

 plants long (4 to 12 cm.), rarely simple : leaves broadly ovate, 

 rounded-obtuse or oblong-ovate, acuminate, mucronate by the

IIab. Wet meadows; Bigtree Grove, California (Bolander); near Salt 

 Lake City (Watson); Yar. angustatum in the Humboldt Mountains,

Tlie species is very variable in all its characters. 



Subgenus III. RHODOBRYUM. 

 Plants fine and large, with a single innovation from under 

 the apex, passing into a stem from the continuation of basilar 

 subterranean stolons. Stem-leaves distant, subsquamiform, the 

 comal crowded, rosulate. Flowers dioecious, discoid. 



41. B. roseum, Schreb. Stem-leaves appressed, oblong-
