I refer this distinct and very pretty Fern, to the Tricho- 

 manes — division of Euasplenium, and it has some affinity with 

 several of the less rigid, herbaceous species of that section ; 

 but is peculiar in the slightly winged rachis, the very dis- 

 tinctly petiolated, rather deeply pinnatifid, lobate pinnae, and, 

 above all, in the long filiform creeping caudex.
