Description
Summary:The little-known species Scapania sphaerifera Buch & Tuomik. is described on the basis of a comparative investigation of the type, and of Siberian materials in which the perianth has been found for the first time. Information is provided on variation, differentiation and ecology of the species. The unique type of gemmae together with the structure of the perianth, character of the marginal leaf teeth and shape of the lobes provide a basis for distinguishing S. sphaerifera as a separate sectio, Sphaeriferae sect. nova.
