In spite of the apparently total absence of atliyrioid sori, I regard Athyrium 
silvaticum (Bl.) Milde [Brachysorus, Presl) as the nearest known relative of this 
fern. In Dlplazium its closest affinity is prohably to />. sorsogonense Presl.

In silva muscosa ad terram, 1,800 m. s. m. (No. 5913). 
A most distinct species, characterized by the swollen spiny bases, large and 
few opposite pinnae, very acnniinate pinnules and minute sori.

Near D. zcylanicum Moore, and D. porphyr</rachis Diels, well characterized by 
the clustered fronds, short and veiy chaffy stipes, and imbricate segments, not 
separate even at the base of the frond.
