Taxonomic studies on type material of the family Trichocoleaceae from Central and South America with two new combinations of the genus Leiomitra

Abstract

  Type materials of Central and South American little-known species in the family Trichocoleaceae are critically reviewed. On the basis of the presence of perianths Trichocolea brevifissa Steph. and T. sprucei Steph. are newly included in the genus Leiomitra Lindb.: L. brevifissa (Steph.) T.Katag. and L. sprucei (Steph.) T.Katag. Trichocolea floccosa Herzog & Hatcher from Costa Rica is newly synonymized with L. sprucei. The worldwide key to the species of Leiomitra is given for the first time.
