List of Vascular Plants. 29 



large-leaved specimens (leaves as much as 75 mm. broad) grow in places 

 that are snovv'-covered ; they are the first to develop in spring, as they have 

 plenty of water and utilize the warmth of the sun even before the snow 

 has melted. 



Empetraceae. 



Empetrum L. 



79. Empetrum nigrum L. Sp. pi., 1753, p. 1022; Lange, Consp. 

 Fl. Groenl., 1880, p. 18. 



Kruuse, East Greenland, p. 153. 



Loc. Germania Land: Danmarks Havn, Stormkap. 



Note. It was found on August 1st 1907 with small unripe fruits, which 

 did not mature during that summer; nor did the year-old fruits found in the 

 specimens appear to have ripened. Near Danmarks Havn it occurred on 

 heather-moor together with Cassiope and Salix herbacea. Further, some half- 

 withered and stunted fragments were seen on a gravelly bank near Storm- 

 kap, but only sterile (Sept. 1st 07). 



Onagraceae. 



Epilobium L. 



80. Epilobium latifolium L. Sp. pi., 1753, p. 347; Chamaenerium 

 lati folium Sweet, Hort. Brit., ed. 2, 1830, p. 90; Lange, Consp. Fl. 

 Groenl., 1880, p. 16. 



Kruuse, East Greenland, p. 152. 



Loc. Germania Land; Danmarks Havn and landward around Dove Bugt. 



Flow. Beginning of July. 



Note. Rather common in stony and gravelly soil near water-courses 

 and on slopes with running water; it is sometimes so conspicuous that it 

 catches the eye from a distance. 



Halorrhagidaceae. 



Hippuris L. 



81. Hippuris vulgaris L. Sp. pi., 1753, p. 4; Lange, Consp. Fl. 

 Groenl., 1880, p. 13. 



Kruuse, East Greenland, p. 151. 



The specimens collected belong to the true H. vulgaris and can- 

 not be referred to the broad-leaved form : H. tetraphylla L. fil. (= H. 

 maritima Hell.), although they bear some resemblance to it (see PI. VI). 



Loc. Germania Land: Danmarks Havn. 



Note. Occurs here and there in ponds in shallow water, and flowers. 



Ericaceae. 



Cassiope D. Don. 



82. Cassiope tetragona (L.) D. Don, Edinb. New Philos. Journ., 

 17, 1834, p. 157; Lange, Consp. Fl. Groenl., 1880, p. 87.
