298 Univcrsifi/ of Cfiliform'd Piihlirationfi. [Botany 



Gnjurtitui Pitcificd is really a C'lioiulnis (since it has the cysto- 

 carpic structure of a Chondrus) and belongs under this species. 

 We cannot feel certain of C. plafi/iius (Agardh) J. Ag-ardh, Init 

 can find no difference between it and the European species. 

 We shall make no attempt to separate the numbers known to us 

 into forms, ])ut if we should do so, they would fall under several 

 form -names. 



Chondrus affinis Harvey. 



Esquimalt, B. C, Hari'ey (1862, ]). 178). 



We have not seen this plant from our territory, but feel that 

 it is probably only another form of the preceding species. 



Irid^ea laminarioides Bory. 



On rocks in the upper sublitoral zone. Puget Sound, 

 Sainuhrs (1901, p. 434) ; Port Renfrew, B. C, Builer <in<l PoU<^ii, 

 Nos. 44, 76, and 77. 



We have not seen these specimens and consecpiently place 

 them under the species without comment. Postels and Ruprecht 

 describe (1840, pp. 17 aud 18) a number of species from the 

 North Pacific Ocean and consequently belonging, in all proba- 

 bility, to our territory, which are possibly forms of this species. 

 They are placed tentatively under the various form-names in the 

 following account according to the descriptions as given l^y the 

 authors mentioned. /. lucera and I. sor'nilh cannot even be 

 guessed at, and 1. (Jornucopiw is referred d()ul)tfully to ^Sarco- 

 phyUh arotica. We have not attempted to refer several of the 

 species noted only from Kamtschatka. 



Iridaea laminarioides f. typica Setchell. 



This is a form common on the Californian coast, with 

 elongated lanceolate and, for the most part, entire frond, answer- 

 ing well to the description and figure of Bory (1828, p. 105, 

 1)1. 11, f. 1, especially D). It has been distributed under this 

 name from San Francisco, California, b\ one of us in Collins, 

 Holden and Setchell, P. B.-A., No. XVI (1899). 



On rocks in the lower litoral zone. West coast of Whidbey 

 Island,' Wash., N.LAi., No. 58!
