I was first led to gather this by observing the cylindrical 

 capsules.

Fronds with the exception of the central line, entirely cel- 

 lular: superfices of both sides similar, consisting of oblong 

 cells, but whereas in the upper, the green globuline which is 

 beautifully developed, for the most part adheres to the parietes 

 of the cells, while in the under surface they chiefly occupy the 

 face : among the spherical, or spherico- com pressed cells 

 but generally perhaps with the more superficial, occur ovate 

 green bodies with a more defined margin, and these generally 

 have some connection* with the parietes, or rather faces of 

 union. Some of these are oblong, as if composed of two or 

 three confluent oval ones. These occur on the faces. 



With the exception of the central thickened line, the 

 frond consists, fas seen on a transverse section) of a simple 

 series of large cells of an oblong or parallelogrammic shape, 

 The central thickened part consists of angular cells with 

 very little globuline, and that of a paler tint, except both 

 superficies which have the usual quantity etc. These also 

 viewed longitudinally are long : the center is occupied by a 

 fascicle having a striate appearance under \ C. A. This stri- 

 ate fibrous line ceases within the apical emargination of the 

 frond, and within the thickened line, which reaehes to the 

 em argination. 



The involucrum is formed from an early period : the tube 

 is short, fleshy, cellular, the margin or limb deeply divided and 

 fimbriate, and some of these divisions are so disposed as to
