f. cloiigata is a very variable plant: podetia apiculate or scyphous, 

 squamose or esquamose, colour testaceous or glaucous; the latter colour 

 (f. ecmogyna Ach.) is by far the more common in our plants. 



The typical f. cloiigata is very robust, but there is every transitional 

 stage between such plants and more slender and elongate ones (f. chordalis), 

 which can only with doubt be referred to either of them, cfr. Norrl. et 

 Nyl. Herb. Lieh. Finn. 421 a, and Wainio's note (Mon. Clad. II p. 99) 

 'Criioiiiycc ecmogyna C. aniaiira Acii. sec. hb. Ach. ad '/]. cloiigataiii . . . 

 et ad y. chonialciu versus vj. cloitgatain . . . pertinet'. Plants agreeing 

 entirely with H. L. F. 421 a are quite common in Norway. According to 

 Wainio they should be referred to f. chordalis. 



f. cloiigata is frequent on all the mountains investigated in Southern 

 Norway; it is quite as frequent in Northern Norway where it descends to 

 the level of the sea. It ascends to very high stations, 1600 m. or more. 

 According to Havaas it does not descend to the forest zone in Western 

 Norway, in Eastern Norway it is also seen in high subalpine forests [Pinus). 



It prefers moist sandy or gravelly substratum, wet ground between 

 stones, and the like.
