Somewhat variable in size and density, form and direction of 

 Ihe leaves. A gracile, dense tufled form is gathered near Thors- 

 havn (R). 



55. J, riparia Tayl. 



B., I., N\v. (\v. c, suba.). — Fær., not rare. On moist rocks and on 

 tlie horders of niountain rills, to ab. 400 m. Colesula frequent. Syd.: 

 Vaag; near Trangisvaag; near Norbes Ejde at Kvalbo (!). Vaago: The 

 east side of the iskind (!). Str. : Ghversrejn; near Nordredal; between 

 Nordredal and Oreenge; Gjoverbotn near Kvivig; Vestmanhavngjov (!). 

 Nol s o (F. B.). Ost.: Næs (R.); near Ejde (!). 



Var. rivularis Bern. 



Ost.: Gotegjov, harren (!). 



Some of the specimens I had at first referred to var. salevensis 

 Bern., but the limits between this and the typical form appears to 

 me too unimportant to keep them separate. 



56. J. atrovirens Schleich., Aplozia atrovirens Dum. 



B., N\v. (c., suba.). — Fær., rare. On moist rocks in low-lying parts 

 of the istands, in liigher parts also on wet gravelly ground on the horders 

 of rills. Fr. rare. Syd.: Ordevig, barren; near Trangisvaag (!). Str.: 

 Saxendalen, barren (!). Ost.: Eastern declivity of Trelavandsskardet, c? (!), 

 near Ejde, barren (R); near the summit of Slattaratinde, fr. (!). 



The only difference of value between J. atrovirens and J. piimila 

 appears to be their genus. I have referred all barren specimens 

 to ./. atrovirens, as the barren state appears to point to the dioi- 

 cous species. 



57. J. pumila With. 



B., I., Nw. (c., suba.). — Fær., ver}' rare. On moist rocks. Vaago: 

 East side of the island, on a prostrate tuft of Philoiwlis fonlana, pa-
