pimifs erect-patent, broadly lanceolate in the inferior ones, but lanceolate in 

 the superior, falcate, long acuminate, short-petioled, pinnatifid near the rachis, 

 gradually becoming merely dentate towards the apex, largest ones about 

 13 cm long, 6-7 cm wide ; pinnules erect-patent, lanceolete, but ovate in the 

 superior ones, cuneate at the ba^e, blunt afc the apex, inciso-dentate, the 

 upper ones flabellato- dentate, the inner lowest one largest; veins pinnate, 

 but flabellato-pinnate in the upper ones ; veinlets not close, simple or 2-

Asplenium bulbiferum Forst, var. Maxim, in litt. 



Nom. Jap. Hayama-sliida (T. Makino). 



Hab. Prov. Tosa : Suginokawa in Hayama (T. Toshinagal 1884;

This is perhaps an extraordinary variety of A. Wrightii Eaton, and 

 is frequently found associated with it in the same locality. Maximowicz 

 considered it as a variety of A. bulbiferum Forst.

 Frond ample, deltoid, acuminate, tripinnate or tripinnatificl, thin, herbaceous, 

 naked ; pinnae spreading or erect-patent, about 10 on each side, subopposite 

 in the inferior, ovate-lanceolate, but lanceolate in the superior ones, acuminate, 

 shortly petioled, rachis very narrowly winged above : pinnules numerous, 

 spreading, a little apart from one another, lanceolate, often slightly falcate, 

 acuminate, very shortly petiolulate in the inferior ohes, pinnate or pin- 

 natiparted, merely crenulato-dentate towards the apex in thes uperior portion ; 

 segments spreading or erect-patent, slightly apart or closely placed, oblong- 

 lanceolate or narrowly oblong, very shortly petiolulate or quite sessile, pin- 

 natifid or crenulato-lobecl, acute or obtuse, J-2J cm long, 2-7 mm broad ; 

 veins pinnate ; veinlets free, erect-patent, simple, or 2-forked in the lower 

 ones, lowest one sometimes pinnate ; main rachis slender, naked. Sori
