Wb, lycopodioides /. typiea a compada Is properly a li- 

 toral form, and occurs most commonly in the lowest part of 

 this zone, but at several places it also appears abnndant a 

 few feet below extreme low-water mark. In scattered indi- 

 viduals I have met with it as far down as abont 10 fathoms. 

 Best developed and most abimdant it grows on somewhat 

 steep rocks on open coast, and in rock-pools betweeu tides 

 on exposed places. It also is met with in rather sheltered 

 ^oves and in somewhat enclosed bays and sounds, but not 

 m the inner of the deeper fjords. 



The species grows commonly 10 — 15 cm. long, but ra- 

 ther often specimens are met with, which have a length of 

 20 — 25 cm. It probably develops repro iuctive organs all 

 the summer, but not richly (perhaps also in winter). I 

 tave tåken specimens with sporocarps and antheridia in Ju- 

 lie and July, at "West Finmarken in May and June, and at 

 Nordland in the middle of February ; tetraspores in June

^^d July, at West-Finmarken besides that in May and Sep- 

 tember, and at Nordland in January. 



Didrihution: Common and abnndant almost everywhe- 

 ^6 along the shore, as a rule wanting or at least scarce in 

 the inner part of the deeper bays.
