are formed from the cortical cells of the antheridial portion. (I have 

 found antherozoicles formed in the same frond bearing procarps. I do 

 not know whether the case is normal or not). Procarps are abundantly 

 formed and are glomerated with an auxiliary cell and sterile filaments. 

 The glomerated mass is carried on a short articulated branch which 



o 



arises as a lateral branch of the basal cell of cortical dichotomous 

 moniliform filaments. There is a little larger cell terminating the 

 articulated pedicel of the glomerated mass ; this cell seems to serve as 

 the auxiliary cell (d. of fig. 17 and 18). From the auxiliary cell many 

 sterile filaments arise and as the branch of the auxiliary cell or of the 

 sterile filaments slightly 'curved procarpial branches are produced 

 which are composed of 3 or 4 cells. Cystocarps abundantly produced 

 in the upper branches immersed in the substance of the frond and 

 slightly swollen out ; neucleus a little lobed and supported on a stalk- 

 like cell. Colour brownish red changing to blackish in drying. Sub- 

 stance soft-cartilaginous and the plant imperfectly adheres to paper in 

 drying.
