specimens which I have collected at Enoshima in March, younger pioEfera- 

 tions have arisen from the older segments. Sporophylls are deyeloped from 



older portion of frond. 



Remarks : At the time when published this plant under the name 

 Cryptonemia WU&oni?, I had not seen any specimen of it. A few 

 months after the publication of that paper. Mr. Reinbold kindly sent me a 

 piece of a sterile frond of Or. Wihoni J. Ag.. thus facilitating my study 



uabling me to compare the plant in question with it. On making 

 the comparison, I have discovered a great difference in the structure of the 

 fr<>nd, so that my plant in question cannot be identical with Cryp. ]Yil- 

 soni. which has been afterward separated by Prof. J. Agardh to form a 

 new genus Blasfojjh/e. 



From the similarity of tetrasporic sporophylls and from that oi the 

 mode <>f growth of the present plant with those ^i Pr. articulata I have 

 referred this plant to this genu-. With that species Pr. Schmitziand 

 seems to Btand in the closest affinity, agreeing in the mode of growth and 

 character- of sporophylls, hut differing from the former in the form of 

 segments and in the presence of proliferations from the surface. The struc- 

 ture of frond i- in some measure different form that of Pr. articulata 

 and other allies. In Pr. Schmitziana, the intermediate layer consists of 

 a few layers of larger roundish cells which are distinctly differentiated from 

 those of the cortical layer. The latter is composed of vertically seriated 

 subcubical cellules disposed in a single longitudinal row. In allied species, 

 the distinction between the cortical and intermediate layer is not so mani- 

 fest as it is in Pr. Schmitziana. In them, cell- of the intermediate layer 

 gradually dimmish in size and pass U> cells of the cortical layer, which are 

 not vertically seriated in a single longitudinal row. 



As I have formerly stated in the paper above referred to, the late Prof. 

 Fr. Schmitz suggested to establish a new genus for this plant, but from its 

 resemblance to Fr. articulata I propose to refer it to the genu- Frionitis. 

 It i- no doubt a plant highly developed in it- habit and .-tincture amongst 

 all the species of this genus.
