Schizoneiira quercifolia f. linearis Collins comb. nov. 



On stipes of Lessonia in the upper sublitoral zone. Port 

 Renfrew, B. C, Butler and Polley, in Collins, Holden and 

 Setehell, P. B.-A., No. 938! 



Collins has distributed the specimens collected at Port Renfrew 

 under the name of Delesseria quercifolia f . linearis. The plants 

 look like eroded and less proliferous forms of the Unalaska plants 

 which we have referred to D. sinuosa. Iu general outline and 

 venation, these several plants resemble '8. quercifolia very much, 

 but that species as found on the coast of California does uot 

 show, in the specimens seen by us, any tendency towards prolif- 

 eration. As none of the specimens are in fruit, we must leave 

 them as given here. 



Erythroglossum Woodii J. Agardh. 



Vancouver Island, B. C, J. G. Agardh (1870, p. 54, under 

 Delesseria Woodii) . 



We have not seen any specimen which may be referred to 

 this species. According to the description, it has a narrow, 

 linear frond (2-3 mm. wide), pinnately branched, with inter- 

 rupted, linear, marginal sori. 



Apoglossum decipiens J. Agardh. 



Upper sublitoral zone. Prince William Sound, Alaska, 

 Saunders (1901, p. 437, under Belesseria decipiens) ; Vancouver 

 Island, B. C. ./. G. Agardh (1870, p. 58, under Delesseria 

 decipiens) : Strait of Juan de Fuca, B. C, Harvey (1862, p. 170, 

 under D. Hypoglossurn var. aroorescens) ; Whidbey Island, Wash., 

 N.L.G., No. 6!; San Juan Island, Wash., Tilden, No. 211!, 

 under D. decipiens. 



A large and beautiful species with both eystocarps and tetra- 

 spores in abundance, extending southward to the central coast of 

 California. 



Pteridium Baerii (Ruprecht) J. Agardh. 



In the sublitoral zone. Sitka, Alaska, Saunders (1901, p. 437, 

 umb-r D. Barii) . 



This species occurs in the Ochotsk Sea, but the above is the 

 onlv locality as vet noted for it on the West American Coast.
