The Hepatic Flora and Floristic Affinity of Hepatics Around Takakia Lake, Queen Charlotte Islands, British Columbia

Résumé

The known hepatic flora of the Takakia Lake area consists of 66 species, 2 subspecies, and 2 varieties, in 30 genera and 18 families. Thirty-seven taxa (51.8%) of the total 70 taxa present are boreal in distribution. Seven taxa (10.1%) are western North American and Amphi-Pacific elements. This clearly demonstrates that the greatest diversity of western North American hepatics occurs between 45°–55°N and between 120°–135°W which includes the lake (Hong 1988). Other distribution patterns include a taxon which is a North American boreal endemic and one which is a North American temperate endemic; two are cosmopolitan and disjunct montane; three are circumtemperate and circum-montane; six are temperate disjunct; eight are arctic and alpine; fourteen are boreal disjunct and twenty-three are circumboreal.
