Systematic position of the moss genus Trachyphyllum A.Gepp (Pylaisiadelphaceae) plus additions to its distribution in the Neotropics

摘要

Representatives of the genus Trachyphyllum are shown to form a monophyletic group. The presence of papillae at both ends of leaf cells, investigated here using SEM, is suggested as a possible synapomorphy. The position of the genus at the family levelis discussed and changed to Pylaisiadelphaceae. In addition, the geographic distribution of Trachyphyllum in the New World is updated.
