172 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



Europe, the Caucasus region, and the alpine and arctic regions of 

 North America. 



A frequent plant, worthy of mention, was the insectivorous 

 Piugiiicida vulgaris L,, also native with us from New Brunswick 

 to Quebec, to Alinnesota and far north. 



Everywhere in the grassy meadows and slopes at the foot of 

 the mountains Potentilla Tormentilla Sibth. was in evidence. It 

 occupies much the same place in the flora as our cinquefoils, 

 Potentilla canadensis L. and P. pnmila Poir., and has a similar 

 appearance, but it has only four petals. In the boggy spots in 

 these meadows could be seen another insectivorous plant, also 

 native with us, Drosera rotundifolia L. With it often grew 

 Saxifraga stellaris L. and Chrysosplenium oppositifolium L., the 

 latter under much the same conditions as our golden saxifrage, 

 Chrysosplenium americanum Schw. 



I must not fail to add our own Myrica Gale L., which, also 

 indigenous there, was quite at home beside a meadow brook. 



The mosses and liverworts are especially numerous, also the 

 algae, but fungi were scarce. Over thirty species of liverworts 

 were collected, and among the mosses was Oedipodiiim Griffithianum 

 (Dicks.) Schwaegr. For a long time this was believed to be the 

 only plant peculiar to the British Isles, until it was discovered in 

 Norway, and it has since been found in Greenland and Alaska. 



Perhaps one of the things which impressed me most through- 

 out the whole trip was the comparatively large number of in- 

 digenous plants which arc also native in North America, for not 

 only those just mentioned, l>ut many of the others named above 

 are reckoned among our indigenous plants. The generally ac- 

 cepted belief in a closer relation or a connection between Europe 

 and America in former geologic times was thus brought home to 

 me more forcibly than ever before; for what could be more con- 

 vincing evidence than to lind such plants as the marsh marigold, 

 the low juniper, and the sweet gale, thrifty and important members 

 of the native flora !
