Ainoiif^ otluT remarkable features in Ihe peculiar abun- 

 (lance of Ibe West Coast it mav be mentioned Ibat out oi' tbe 

 14 Ericdveiv (sens. lal.) louml iii (Ireenlaiul, half are found 

 onlv in West Greenland, viz. Andromedd (jldtuophiilla, A. 

 polif'dUit, Arclosldphiilos iiini iirsi, Lednm (hrutnhens- L. qroen- 

 Utndiciim, Oxycoccns and Vnccinium nilis idwd. All must be 

 presumed lo bave come from N. America. Sonietbing similar 

 is found in tbe case of tbe genus Pedicnlaris wbicb in West 

 Greenland comprises 8 species, whereof only 3 (P. /hunmea, 

 P. hirsnta and P. htppoiiica) are also found in Kast Green- 

 land; bere also tbe remaining 5 species are of American 



ongMi.

 tbe West Goast sbould, outside Greenland, be sougbt in 

 N. America, and tbis also proves to be tbe case witb nearly 

 all of tbem; tbere are, bowever, two species (tbe Norse 

 piants bave already been mentioned) wbicb nro known 

 from Europe (Scandinavia, but not Iceland), but not yet 

 found in Nortb America; tbese are: Corex holosloiud and 

 C. ru/ind. Botb are inconspicuous and not very cbaracter- 

 istic; it is likely tberefore tbat tbey will in course of 

 time be discovered botb on the Easl Coast and in 

 N. America. 



Among the species wbicb bave immigrated to West 

 Greenland from N. America Ave bave first of all a contingent 

 of soutberly species, e. g. Slreptopus dinplrxi/hlins, Orchis 

 roliindifolia, Sorhus decord, Alniis crisjxi, Cormis cdiiddeiisis, 

 Viold Selkirkii and Anemone Hichardsonii; tben come a few 

 common arctic species, sucb as Arleniisid horcdlis, Ledum 

 decnmhens. Primula (arinosa (/rociddndicd, Pedicnldris Umala;
