Dryopteris fijiense (Hook.) C.:Chr. is a closely related species 
but may be distinguished from D. rubiginosa (Brack.) Kuntze by 
its more open divisions, by the ciliated margin of its pinnules, and 
by its ciliated indusia, in contrast to the compact form and entire 
margins of the pinnules and indusia of D. rubiginosa. Compare

There is a strong superficial resemblance between Dryopteris 
honolulensis (Hook.) C. Chr. and Dryopteris latifrons Brack., but 
the small submarginal, naked sori distinguish the former. 
DRYOPTERIS CRINALIS (Hook. & Arn.) C. Chr. Ind. Fil. 259. 1905 
Polypodium crinale Hook. & Arn. Bot. Beech. 105. 1841.

Hillebrand B; Kauai, Forbes 269 BM; Johnson B; Heller 2587 C; 
Robinson 412 V; Hawaiian Islands, Baldwin 75 C; Baldwin B;

Young specimens of D. crinalis are gray green in color, while 
mature specimens are rusty in appearance owing to the leathery 
texture and scaly under surface of the leaves.
