The arctic element Canada shares mostly with Europe, and as stated above several species are circumpolar, and it deserves attention that many of these Cana- dian Carices represent alliances analogous to those of the old world, exmplified by types of a corre- sponding habit and general aspect. So far as concerns the greges we have seen that Canada is the home of certain ancestral types, formae hebetatae, which are absent from Europe, in other words several of the greges are more amply represented here by possessing these types in con- nection with the centrales, and passing gradually into some more or less deviating: desciscenies. The presence in Canada of such characteristic species as those of the Lejochlaenae, mostly sylvan types of rare morphological structure, and of south- ern origin, indicates the enormously wide distri- bution of the genus on this continent, and its ability to adapt itself to the environment, far north and far south. And the alpine flora with its arctic species intermingled with endemic or more southern types is a tangible proof of the foundation of the theory relating to the history of the arctic fl during the glacial epoch.
