Among easily recognisal)le species, Melandrijnm tviflorum 

 was long regarded as endemic to Greenland, which was 

 very reniarkal)le, as it is a species very widely dislrihuted 

 in Greenland itself, ranging from the North Coasl to ahl. 

 67^ on the West Coast and abt. 72^ N. Lat. on the Easl. It 

 was several times recorded from arctic America, but closer 

 investigation ahvays showed that the determinations were 

 erroneous. 



Now however, it appears after all, as first pointed out, 

 I think, by M. P. Pousild, that a plant from the mouth 

 of the Mackenzie River, described as Li/chnis trifloni var. 

 Ddwsoni H. L. Robins., is the same as .17. tri/lornm; and 

 this, after having seen the original specimen, I can myself 

 conlirm. This remarkable instance of endemism was thus 

 disposed of. It is nevertheless rather surprising that the 

 species has not hitherto been found clsewhere in Ihe wide 

 expanse of arctic America. 



The number of endemic species is at present 8, viz. : 



Jirai/a Thorild-Wnlfjii, Tdraxacnm arcUxjenum, Polamo- 

 (jeloii qroenUindiciis, Antennaria intermedid.
