for future. In 1912, I had an opportunity to study the type 

 of Kjellman's species at Upsala. 



There are two specimens under M. lepidodermum Kjellm. 

 in the Herbarium of the Botanical Museum of Upsala. One 

 is from Holstenborg, Greenland, collected by Ostenfeld, un- 

 doubtedly one of the specimens noted by Rosenvenge in his 

 2 me. Memoire, p. 117. The specimen reminds us in its out- 

 ward appearance of a small form of Enteromorpha Linza by 

 having a long, filiform basal portion expanded upwards into 

 a spathulate blade. The other is the type from Nova Zembla. 

 It is a fragmentar}- specimen without the basal part, being 

 simply a broad membrane of about 10x6 cm. I can not find 

 a good reason to identify Miss Tilden's plant with Kjellman's 

 except that both have the thickness of membrane and the 

 form and size of cells nearly equal. M. zostericolum, as far 

 as I could find, is always growing epiphytic on Zosters, only 

 occasionally on other algae. Its frond is usually 2-4 cm high, 

 seldom reaching 6 cm. It entirely differs from M. lepidodermum 

 in habit and size of frond. Collins observes that the Green- 

 land plant would not be identified with Kjellman's species. 

 The two specimens of M. lepidodermum at Upsala, as alluded 

 to above, appear indeed to justify his observation. By the 

 similar reason I have but to retain M. zostericolum Tilden 

 as a distinct species. 



Miss Tilden remarks that the species should probably be 

 placed between M. fuscum Wittk. and M. lepidodermum 

 Kjellm. Kjellman has related some affinity between the latter 

 two. But the present species has nothing to do with .1/. 

 fuscum, and perhaps very little with M. lepidodermum. In 

 ha hit and general characters of frond it stands rather near 

 by -U. (•rcvillci Wittk. 



Locality. Northern E£uriles(!); Nemuro(!); Muroran(!); 

 Bakodate(I). 



Distribution. Vancouver Island; I'ultcI Sound.
