Entosthodon.] BRYACE^. 199 



From imperfect specimens kindly communicated by Mueller we find 

 that, as in P. acuminatum, the leaves are entire at the apex, or nearly so, 

 and the form of the operculate capsule is nearly the same. It differs, 

 however, in the larger leaves, not ovate but rather linear, the capsule 

 longer-pedicellate, without coUum, and the lid longer-mamillate or ob- 

 tusely rostrate. The stems are much longer and more divided; the male 

 brandies long, like the fertile innovations. 



73. ENTOSTHODON, Schwaegr. (PI. 4.) 

 Plants annual or reproduced by innovations, simple or branch- 

 ing. Leaves variable, even in the same species, with a loose 

 hyaline soft areolation. Flowers monoecious, terminal, the 

 male on the primary stems, the fertile on the innovations; 

 antheridia short ; paraphyses inflated at the apex. Calyjitra 

 vesiculose-cucuUate, long-beaked, shining. Capsule thick, sub- 

 cernuous or pyriform in connection with its collum ; marginal 

 cells rectangular, in many transverse series ; lid small, plano- 

 convex. Peristome attached far below the orifice, either very 

 rudimentary, or, as in all the xlmerican species, of 16 distantly 

 articulate teeth, trabeculate on the inside, narrow, confluent at 

 base. Annulus none. Spores large. 



1. E. Drummondii, Sulliv. Plants cespitose, gregarious, 

 yellowish green ; stems very short : leaves tufted, obovate, 

 lanceolate or Ungulate-lanceolate, concave, more or less dis- 

 tinctly crenulate by the prominence of the yellowish marginal 

 cells : capsule short, symmetrical, oblong-pyriforra and enlarged 

 at the orifice when empty ; pedicel comparatively long, flexuous ; 

 lid convex, apiculate ; teeth linear-lanceolate, dark red, granu- 

 lose, striolate lengthwise ; articulations distant : spores reddish 

 brown, subpapillose. — Mosses of U. States, 51, t. 4, and Icon.
