a locality showed that colour, sometimes only a single one among many 

 normal green ones, sometimes also only part of a tuft was so coloured. 

 The tufts, which can reach a considerable size, are very hard and 

 compact. 



Generally it grows in open gravelly soil, especially in slopes lo the 

 southward, hut it may also he found in level plains both in the low 

 land as well as in the higher plateaus. It flowered from the end of 

 June, and often the tufts were found entirely covered with blossoms, or 

 later, with capsules.

The greater part of the specimens may be referred to f. alpina, 

 Wahlenberg, Fl. Lapp., p. 99, but there is no distinct line between 

 this and the narrow-leaved form, which is also found. Consequently, I 

 have not thougt it necessary to distinguish them. 



It is rather commonly spread especially in moist densely vegetation- 

 clad rock ledges and slopes, but also in other localities. Flowered rather 

 sparingly from the beginning of July.
