X M. floerkeanum Sch., var. henrici Ren. & Card. 

 This differs from the typical form in the green color of the plant, and the 

 excurrent costa, often hyaline at the point. Saline Co.', on sandy 

 ground (Henry, Bot. Gaz., Vol. XIV, p. 91).

GYMNOSTOMUM, p. 52. 



Lid falling early; capsule thin walled, with 3-4 rows of transversely elongated 

 cells at mouth.

WEISIA, p. 55. 



Inflorescence autoeeious ; teeth more or less perfect, or none. 



Capsule wrinkled lengthwise when dry * W. viridula Brid. 1 



Capsule narrower, lid long beaked, curved, teeth nearly entire.

DICRANELLA, p. 64. 



I. Cells of exothecium rectangular quadrate; seta red; costa usually broad and 



indistinct below. 

 A. Leaves not sheathing, erect, spreading. 

 Costa percurrent, or excurrent : annulus none, peristome papillose. 



Capsule cernuous, curved * D. varia Sch. 6 



Capsule erect, symmetric D. rufescens Sch. 7 



II. Cells of the exothecium prosenchymatous ; seta often yellow ; costa narrow 



and well defined below. 

 Seta yellowish. 



Capsule cernuous, not strumose D. heteromalla Sch. 10 



D. varia, Shawnee (Cragin & Becker); Saline (Henry); common. It differs 

 from the type in having a long beaked lid, teeth pellucid at 

 apex, reddish at base, bifid, vertically striolate; it is probably a 

 variety. D. rufescens (Smyth's Check List). D. heteromalla, 

 Saline (Henry), a sterile form with shorter leaves; rather doubt- 

 ful species. 



DICRANUM, p. 67. 



"In this genus the structure of the costa is of diagnostic value. It is either 

 composed of similar cells (homogeneous) or composed of large parenchymose cells
