I have had specimens for investigation from the following 
localities: — West Greenland: Sukkertoppen (July 5, 1884, Th. 
Holm); Tatsip-ata (July 15, 1884, Th. Holm); loc. ign. (July 20, 
1884, S. Hansen). East Greenland: loc. ign. (Aug. 1892), Dron- 
ning Louises ©. Norway: (Finmark) Bosekop (1885, E. W.); 
(Dovre) Vaarstien (July 13, E. W.); Storlien (July 20, 1894, 
F. Börgesen); Lille Elvedal (July 11, 1887). [Sweden: Härje- 
dalen).

cases chlorophyll grains occur 
(Livrorss, p.75). In the fur- 
rows the epidermis is thin and has very prominent stomata 
which are rather thickly covered with two kinds of hairs — 
unicellular bristles, and multicellular, glandular hairs. The 
stomata are placed obliquely to the longitudinal axis of the 
leaf, as in the case of ericoid leaves with furrows.
