Nr. 3. (I. H. Ostenfeld: 



of America II origin, Ibuiul on the West Coasl and here, 

 1)11 1 nowhere else on the East Coast, viz. Arabis liolboeUii 

 aiul Drijoplcris fnujraiis; two othor Aineiicau species also 

 have, so to speak, juniped IVoin the West Coast to this 

 (listrict. viz. Arabis arenicola and Saxifraga tricusj)id(it(t. 

 These 4 AnuMJcan species shonld most naturally he supposed 

 lo have heen carried across the inland icc the seed-bcaring 

 portions having heen swept over the surlace ol" the ice by 

 storms. We have then some species of eastern origin: Braijd 

 qlabella, (Uire.r parallela and Saxifraga hicntciifolia, which 

 belong specilically to the East Coast, and some more 

 southerly species such as Alchimilla glumerulans, Taraxaciiin 

 brachyceras, Carex alpina and microylochin. Hieracium alpinuni 

 and others. 



The district norlh of Scoresby Sound (E. VI) is, it is 

 true, rather poor in species, but the deep fjords do provide 

 some sheltered sites, and it is only wilh District E. VII 

 that the true high-arctic poverty is distinctly aj)parent. 



The harshness of the climate on the East Coast is un- 

 douhtedly due to Ihe ice masses of the mighty Easl Green- 

 land polar current; we have here a striking contrast to the 

 conditions prevailing on the West Coast. 



Altogether, the East Coast has only i) species peculiar 

 to itself, as against the 134 of the western side. These are: 

 Scdiun (icrc and Alchimilla aciitidens, already noted, and 

 Arenaria ciliata pseiulo-frigida, Brai/a glabclla, Draba repens, 

 Saxifraga liieraciifolia, Polemonium boreale, lianunculiis qlaci- 

 alis and Carex parallela. The last seven, ol which .'{ have 

 been mentioned under Scoresby Sound, are arctic species, 

 and of these, only Ran. glacialis is found in Iceland; this, 

 like the remaining six, may most naturally he supposed to 

 have been brought from the norlh-east bv the East Green-
