of Grimmia lawiana (Bryopsida: Grimmiaceae) from the continental Antarctic

ABSTRACT: On the basis of the distinctly biplicate and carinate leaves in the distal portion Grimmia lawiana J.H. Willis, the only continental Antarctic endemic moss species, is trans− ferred to the genus Coscinodon Spreng. and the new combination C. lawianus (J.H. Willis) Ochyra is proposed. The sp...

Description
Summary:ABSTRACT: On the basis of the distinctly biplicate and carinate leaves in the distal portion Grimmia lawiana J.H. Willis, the only continental Antarctic endemic moss species, is trans− ferred to the genus Coscinodon Spreng. and the new combination C. lawianus (J.H. Willis) Ochyra is proposed. The species is described and illustrated, its affinities are discussed and its geographical distribution in the Antarctic is mapped. Grimmia reflexidens Müll. Hal., a southern South American endemic species from Chile, is briefly assessed and this species is also shifted to Coscinodon as C. reflexidens (Müll. Hal.) Ochyra, comb. nov. A key to all species of the genus Coscinodon is presented. Guembelia longirostris (Hook.) Ochyra et Żarnowiec is reported for the first time from the Antarctic on the basis of a specimen col− lected from the Nordenskjöld Coast on the eastern coast of the Antarctic Peninsula.
