Nitophyllum Harveyanum J. Agardh. 



Puget Sound, Nott (1900, p. 31). 



Known only by a single specimen from pur territory. The 

 species is Australian, and also occurs locally in several localities 

 on the Central Calif ornian coast. 



Nitophyllum Iatissimum (Harvey) J. Agardh. 



On stones and wood in the lower litoral and upper sublitoral 

 zones. Esquimalt, B. C, Harvey (1862, p. 170, under Hyme- 

 neiia latissima) ; west coast of Whidbey Island, Wash., h.L.G., 

 No. 93! ; Port Orchard, Kitsap County, Wash., Tilden, No. 212! 



A variable species, especially as to outline, prominence or 

 obsolescence of the veins, color, etc. Miss Tilden 's specimen is 

 very fragmentary, representing a. proliferation of an old plant, 

 but seems to belong here. Harvey's plants, the types, are sep- 

 arated into two species by J. G. Agardh, the second of which is 

 his N. stenoglossmn (cf. J. Agardh, 1898, p. 92), biit which we 

 are inclined to refer to N. violacewm. Gardner's plant belongs 

 to the N. macroglossum of J. Agardh, but, as Nott has already 

 shown, is probably only a seasonal variation of N. Iatissimum 

 (cf. Nott, 1900, pp. 19, 20). 



Nitophyllum Ruthenicum (P. & R.) Kjellman. 



On various Laminariacea? in the sublitoral zone. St. Paul 

 Island, Alaska, Herb. Farlow, legit Whitel (Setehell, 1899, p. 

 •">!)4); Sitka, Alaska, Saunders (1901, p. 437); west coast of 

 Whidbey Island, Wash., N.L.G., Nos. 114!, 115!, 266!. 



This species is intermediate between what passes for X. 

 Fryeannm. and N. spectaliile D. C. Eaton. The veins are incon- 

 spicuous and often scanty, and confined, as a rule, to the very 

 base of the frond. Saunders (loe. cit.) speaks of this species 

 as being intermediate between j\ t . Iatissimum and A. Fryeanum. 

 We have compared our specimens with specimens kindly sent by 

 Professor Kjellman, and can find nothing in common with N. 

 Iatissimum.
