Alaria fragilis Saunders. 



In the snblitoral zone. Kiikak Bay, Prince William Sound, 

 and Glacier Bay, Alaska, Saunders (1901, p. 425). 



It certainly seems to us that this plant is likely to prove to ])e 

 nothing- more than a variety of A. l*ulaii with a somewhat 

 elongated stalk, such as certainly does occur among plants of that 

 species. The distant sporophylls as well as their shape is due ta 

 the youth of the plant. 



Alaria fragilis f. bullata Saunders. 



With the last. Glacier Bay, Alaska, Saunders (1901, i). 425). 

 Apparently only a state of the last. 



Alaria valida Kjellman and Setchell sp. nov. Plate 21. 



Stipe short, 1-5 cm. long, c.ylindrical , at first slender, but at 

 length stout and showing rings of growth, reaching a diameter 

 of 13 mm., showing also a well developed cork layer. Rhachis at 

 first short, becoming very much elongated, up to 15-20 cm., 

 somewhat flattened, obtuse on the edges, stout like the stipe. 

 Sporophylls linear lanceolate, 15-50 em. long and 3-6 cm. wide, 

 with margins undulate and all except the narrow margins and a 

 small portion of the tip occupied by the sorus. Blade long, up 

 to 3-4 meters, 15-25 cm. wide, tapering very gradually to the 

 base, with broad midrib (22 mm. wide) which is little prominent 

 and abruptly narrowing towards each end in cross section. 



This belongs to the grouj) of species with l)road midril^s 

 and is fairly nearly related to A. laticosfa Kjellman, l)ut differs 

 from that species chiefly in the stouter stipe and rhachis and the 

 longer and broader sporophylls. Its relation to .1 . mayfirnafa 

 P. & R. is still to be settled. 



In the snblitoral zone. Unga, Alaska, A.A.L., No. 5059!: 

 west coast of Whidbej' Island, Wash., X.LJi., No. 111! 



Specimens of the above collections were sent to Professor 

 Kjellman, who recognized them as belonging to a new species. 

 We have drawn ii]) the descrii)tion and given the name to tlie 

 plant on account of the broad stipe and rhachis. In the type,, 

 the stipe is short, but in the following form it is mudi longer.
