Previously known from northern British Columbia (Hulten 1968; Porsild 1951) and several sites in southwestern District of Mackenzie (Cody 1963; Scotter and Cody 1974). Athvrium filix-femina ssp. cvclosorum (Ladv Fern). 24473(1).' This appears to be the second report of this species from the Yukon Territory. Porsild (1951) found A. filix-femina ssp. cvclosorum at a hot spring site in the Mayo District. In the southwestern District of Mackenzie it is known from only three localities (Jeffrey 1961; Porsild 1961; Scotter and Cody 1974). two of which are hot spring sites. * Dryopteris spinulosa (Spinulose Wood Fern). 24468, 24472. 24482 (1)..
