The geographical distribution of Anastrepta orcadensis presents 
several points of interest. In Europe it is more or less abundant 
in the higher mountain ranges, reaching lower altitudes in the 
British Isles, the Faroe Islands, and Scandinavia. Then it 
reappears in the Himalayas, in China, and in the Hawaiian Islands. 
Its discovery in Alaska marks a very noteworthy extension of its 
knowa range. 
Although Lindberg knew the plant from sterile material only, 
he pointed out the fact that it differed markedly from the species of 
Jungermannia, subgenus Eujungermannia, section Lophozia—the 
genus Lophozia of most recent writers—and proposed the new 
section Anastrepta for its reception. This section was soon raised 
by Schiffner to generic rank, although he was still in ignorance of 
the reproductive branches. At the time of its publication as 4 
genus Anastrepta was monotypic, but Stephani has recently 
transferred to it two additional species from the Straits of Magellan. 
The habit of Anastrepta differs strongly from that of Lophozia, 
the stems being erect or ascending and forming loose tufts. The
