Bryochenea sachalinensis (Thuidiaceae) New to North America in South-Central Alaska
O'Brien TJ. 1993. Bryochenea sachalinensis (Thuidiaceae) New to North America in South-Central Alaska. The Bryologist. 96(2):205-209
Specimens of Bryochenea sachalinensis from the Talkeetna Mountains, Alaska are the first North American collections of this moss. They were found on humus in mesic tundra with granitic or granodioritic outcrops. The addition of Alaska to its range reveals that its distribution parallels that of a number of other bryophytes in the North Pacific Coast element. Bryochenea sachalinensis differs in part from Helodium s.s. by occurrence in mesic (not hydric) habitats and by small dioicous plants with filiform, branched-filiform and laciniate-foliose paraphyllia.
