89. A г a b i s a 1 p i n a L. — On somewhat wet moraine soil. 

 Prøven (Kane); Ingnerit Fjord (Ryder); Svartenhuk's Næs (Taylor); 

 Tartusaq: rare; Sarfarssuit, and Igdlorssuit: not frequent and not, as 

 is the case further south, in large growths along rivers and copses. 

 Strangely enough it was not noticed at the heads of the fjords. 



90. Arab i s Ho оке ri Lange. — Found at Prøven (Hart). 



91. С ard ami ne pratensis L. — At the head of Amitsuarsuk 

 there occurred in damp moss one single, small, sterile individual 

 with a few leaves. We searched in vain for others in the same and 

 in other places. 



92. Cardamine bellidifolia L. — In open spots on heath 

 and on moraine material ; not common, but probably overlooked 

 sometimes. Prøven (Тн. Holm); Lakse Fjord, at Orpik; Amitsuarsuk, 

 and Schade's Islands. 



93. Eu trema Edwarsii R. Br, — We had specially set ourselves 

 to find this rare plant, and we searched for it everywhere, but not 

 until Tartusaq, 71° 31', did we find it, and we found none elsewhere. 



Lange records, on the authority of Vahl, that the specimens 

 found at Niakornak in West Greenland grew "in fertile, someAvhat 

 damp localities at the foot of the mountains." Abromeit gives a 

 similar description of the habitat of Vanhöffen's specimens, while 

 Simmons found his in Ellesmereland "in a dry bed of a rivulet." 

 With regard to the two known habitats on the east coast there are 

 no notes to hand concerning their nature, and very little has been 

 said regarding the localities in Spitzbergen and Nova Zembla, 



On account of the above information given in Lange's and 

 SiMMONs's notes, which do not entirely agree with each other, we 

 searched for the plant especially in protected localities and then in 

 river-beds. As we had found immediately on arriving at Tartusaq, 

 some extreme northern species, I instructed my sons to search 

 exclusively for Eutrema. Very soon we found in a bog a large fruit- 

 bearing individual almost completely hidden in moss, and a little 

 later we found a flowering seedling-plant on the edge of a moraine. 

 After some two hours search we had found about 15 flowering or 

 fruiting, full-grown plants in the bog, while in the moraine-clay 

 exposed to the wind and deficient in snow during the winter we only 

 found some 4—5 quite young seedlings. Here the species decidedly 

 appears to prefer damp moss-bogs ; in such a locality the individuals 

 attained to a height of 15 — 20 cm. and almost all had finished 

 flowering. 



The morphology of this rare plant does not appear to have been 

 studied since R. Brown established the genus and species; I shall 

 therefore return to it on another occasion.
