Ditrichum lewis-smithii (Ditrichaceae, Bryopsida), a new species from Antarctica
In the Antarctic botanical zone the genus Ditrichum Hampe (Ditrichaceae, Bryopsida) is represented by three species, D. austro-georgicum (Card.) Seppelt, D. brotherusii (R. Br. ter.) Seppelt and D. lewis-smithii Ochyra sp. nov. The latter is closely related to D. immersum Zanten from the sub-Antarct...
