ROBINSON: PTERIDOPHYTA OF THE HAWAIIAN ISLANDS 205. 
SPECIMENS EXAMINED: Hawaii, Lichtenthaler N; Maui, Mann & 
Brigham 487 N; Wilkes Expedition N; Kauai, Heller 2544 C, N;

Christensen, following Diels (E. & P. Nat. Pfl. 14: 194. 1899), 
makes Cyrtomium caryotideum a synonym of Polystichum falcatum 
(L.f.) Diels. However, as Polystichum has free veins and this group 
has anastomosing veins, they are separated on that character rather 
than combined on the similarity of their indusia. The type of 
Polystichum falcatum is from Japan. Thunberg, Fl. Jap. 336. $l. 
306. 1784, describes and figures it, but his figure represents 
a plant with cordate-falcate leaves not auricled, with scales 
at the base of the leafstalk. The Hawaiian plant resembles 
Wallich’s specimen at Kew, a tracing from which is in the herbarium 
of the New York Botanical Garden.
