no specimen of the species of this が rms). On examining the fracture 
of nucleus I found that there is, connected with surrounding ち lament— 
ous plexu も a basal placental cell, on which rests a sub 巧 ' lindrical gra- 
nular ce ル む om which a globular mass of spores are radiated. Eacb 
spore is enclosed with a colorless p が ispore, which is also the case in 
Cry が 0 . angu な a. The piresence of り ns granular cell I thought to be a 
characteristic point distinguishing the piresent plant from the genus 
Cryptonemia. On examining the nucleus of Cry が onemia angusta for 
comparison， (as I have no specimen of Cryptonemia, as I have shted 
in other pages) i found the strucjture of nucleus to be similar. Other- 
wis も I could not find any distinguishing character in this plant. If I 
am to consider the piresent plant as a new genus, I must take the 
difference of habit and the presence of sporophyJls froD：i the surface 
of : frond into account. But such secondary characters seem to me to 
be insufficient to e が ablish a new genus. 
In the course of my study I found a new species of Cnjptonemici 
established by Prof*. J. A が rdh ， んん Crypt. Wilsoni •け . Ag. Till Alg. 
Syst. Vol. IV p. 25). It が ems が ! 'ongly to resemble my plant, so much 
so that I am inclined to consider whether it is not identical with my 
plants. Its veinle が large-sized fVond, pinnated by marginal linear- 
lanceolate proli:feratioi: け ， its color and siructure induces me to identify 
my plant with his specie ん 打 is plant was not furnished with no む uits, 
but he mentions the presence oi dot like protuberances — い Fronds adul- 
tiores nunc macu じ s pumctiformibus sparsis ins か uctas vidi ; at frus れ a

tuberances, I suppose to be the beginning of sporophyll も &s I met with 
the similar case in my plant. If this supposition of mine proves to 
be correct, the sporophylls will be found over the む ond in his plant. 
• Thus at first I considered this plant as a new species of Grypto- 
nemia, and in the next place I inclined to e が ab じ sli it in a new genus 
under the name Schmit%ia ; but lastly, on comparing my plant with 
the desci’iptiion of Gnj が. JVilsord J. Ag.， I came to incline to identify 
the present plant with his species. But as I have not seen his plant ， 
I marked m ダ • plant with (?). If my plant afterwards proves to be not
