This is sparingly found in mountainous districts in the southern part 

 of Japan. The filiform stem, capillaceous petioles and petiolules, and 

 small segments of the leaves are the peculiarities of this species. 



Asplenium (Euasplenium) mesosorum Makino Contr. Stud. Fl, dap. 

 III. in Bot. Mag., Tokyo, XII. 1898, p. 88. 



Caudex short, creeping, rather densely rooting, armed with basal 

 remains of old stipes. Stipes elongate, scaly at the base ; scales brown, 

 lanceolate, acuminate. Fronds ample, deltoid, tripinnate, flaccid, thin, 

 herbaceous, very thinly scaly ; pinnae ovate-lanceolate in lower ones and 

 oblong-lanceolate in the upper, attenuated acuminate ; pinnules narrowly 

 deltoid, apparently petiolulate except the superior ones; tertiary segments 

 usually sessile and confluent into the narrowly winged rachis, but very 

 shortly petiolulate in most developed ones, pinnatilobed on the margin ; lobes 

 obtuse, crenulate. Veins pinnate in the tertiary segments ; veinlets mainly 

 2 -forked and the lower ones often also pinnate. Sori conspicuous, narrowly 

 oblong, obtuse at both ends, usually a little curved outwards, parallel with 

 and close to it on each side of the midvein of pinnules and even inferior 

 tertiary segments, not diplazoid ; indusium membranaceous, with involuse and 

 entire margin. Stipes and rachis glossy, darkish ferruginous.

This comes nearest Asplenium. Wheeleri Baker, which is said to be- 

 bng to the Diplazium section, but my species is apparently peculiar one 

 <>f the Euasplenium.
