var. /3* rigens. Shoots erect, slender, inter- 

 rupted, two or three times innovant from the 

 upper amphigastria ; leaves adpressed, scalate, 

 imbricate, entire; amphigastria frequent, 

 subulate. 



var. y compressa. Stems short, erect, rigid ; 

 leaves orbiculate, plane, more crowded and 

 compressed near the apex; amphigastria 

 broadly subulate, patent; involucral bracts 

 larger, entire, connivent, pale green. 



" This species may always be distinguished from 

 other entire-leaved Hepatics by the peculiar 

 nucleate bodies, of two to four granules, arranged 

 in a line, contained in the leaf-cells" (fig. 155). 



Nardia geoseypha, Not., Lind. 



Autoicous. Smaller than N. scalaris, barren 

 stems very slender, terete, creeping, radicu- 

 lose ; fertile stouter, ascending only at the 

 apex; leaves accrescent, lower ones entire 

 or emarginate, orbiculate ; involucral leaves 

 broader, repand-lobate ; amphigastria rare on 

 the barren stems ; upper ones lanceolate, 

 trifid ; involucre immersed, seated at right 

 angles with the stem, gibbous at its base ; 

 the cortical layer and rootlets purple.
