MT7SC1 HEPATIC*. 2i 



The. fructification has not hitherto been observed by me. 

 It is smaller, and of a more delicate construction than the 

 rest. The color green of yellow — no pubescence except 

 the interspersed (iliac of the margin.

This highly remarkable moss comes nearest I. si.vuata, 

 but is so different in many respects, that I cannot omit it 

 new spe< i( ^. although it has been but imperfectly ob- 

 served. 1 accidental!} drew a patch of it out of the water 

 and mud of a pond near Little River, Cumberland county, 

 with CJtriculariae. 



The Irons is about one-eighth of an inch in breadth. 



Remark. Most of the Jungermanniae arc in fructifica- 

 tion in advanced spring: many are so already in winter. 

 V number are very rarely found in fructification, especial- 

 ly of the last division, and, generally, those which grow 

 in water. Such individuals of these as are left dry, are 

 the most likely to fructify. 



2. MARCH AXTIA. Linn. 



Remark. The specific differences of the Marchantiae 

 are mostly taken from the form and manner of the female 

 parts of fructification, and of the common receptacle. But 

 the frons appears to me, in many instances, to deserve 

 equal attention.

My American specimens are from Pennsylvania, not 

 having found it here as yet. It cannot be confounded with 

 any other species, on account of the remarkable radii and 

 very long peduncle of the female receptacle. The nerv of 

 the frons is generally brown.

This is by far the largest and most elegant Hepatic I
