Dryopteris caryotidea (Wall.) Underw. 



Aspidium caryotideum Wall. Cat. a. 376. 1828. 



This species was first detected at an elevation of about 3000 

 feet, on the side of a gulch on the ridge west of the Hanapepe 

 river, Kauai. Later it was noted in a deep valley above Wa- 

 imea, at about 2000 feet elevation. It prefers rather open situ- 

 ations, and does not appear to be plentiful. It differs, accord- 

 ing to Hillebrand, from Asiatic plants of this species.

Dryopteris cicutaria (Swartz) Kuntze, Rev. Gen. PI. 812. 

 1891. 



Aspidium cicutarium Swartz, Schrader's Journ. U:279. 1803. 



In a deep gulch at the foot of the tabular summit, above Wa- 

 imea, Kauai, at about 2000 feet elevation. It was also noticed 

 in upper Pauoa and Kalihi valleys, Oahu, near streams.

Dryopteris cyatheoides (Kaulf.) Kuntze, Rev. Gen. PL 812. 

 1891. 



Aspidium cyatheoides Kaulf. Enum. Fil. 234. 1824. 



Common, growing on the ground, in open places in the lower 

 forest Oahu (1991). On Kaholuamano, Kauai, growing along a 

 stream in the woods, a large form was collected, with wider 

 and much more closely imbricate pinnae (2857). 



Dryopteris fllix-mas (L.) Schott. Gen. Fil. 1834. 



Polypodium filix-mas L. Sp. PL 1090. 1753. 



Common on Kauai, in damp woods, at elevations of 2000 to 

 4000 feet. Collected first on the ridge between the Hanapepe 

 and Wahiawa rivers (2587), and later on Kaholuamano (274(5). 

 The specimens referred to this species are quite different from 

 the European or American forms. 



Dryopteris filix-mas var. parallelogramma (Kze.) Underw. 



Aspidium filix-mas \3li. paralle logramma Kze. Linnaea 13:140. 1857. 



At an elevation of about 3000 feet, on a dry ridge, west of 

 the Hanapepe river, Kauai. Compared with the ordinary 

 forms of the male fern, this would certainly be a distinct spe- 

 cies.
