Evolution and speciation inPellia, with special reference to thePellia megaspora-endiviifoliacomplex (Metzgeriales), III. Chromosome length

Abstract

Studies of the relative and absolute lengths of mitotic chromosomes show that P. endiviifolia is cytologically distinct from the species P. megaspora, P. epiphylla and P. neesiana. This supports the recognition, on morphological grounds, of P. megaspora as a species distinct from P. endiviifolia.
