On Lopholejeunea zollingeri

Abstract

  I consider Lopholejeunea zollingeri and L. nipponica as conspecific. These species have the following characters in common: (1) the crenulate margin of leaf-lobe, (2) the strongly recurved apex of leaf-lobe, (3) the small, inflated leaf-lobule, (4) the apex of leaf-lobule widely connate with the lobe-lamina, (5) the large underleaf recurved or often with flat apical margin and deeply sinuate line of insertion to the stem, (6) the dentate or often nearly smooth margins of female bract and bracteole, (7) the small lobule of female bract, (8) the perianth narrow toward base (so pedicellate in appearance), (9) the perianth with toothed keels, the teeth often connate with each other at the bases, (10) the long and densely branched stem, and (11) the blackish brown pigmentation.
