Lectotypification of the name Tetraphis pellucida Hedw.(Bryophyta)

摘要

Selection of a lectotype for the name Tetraphis pellucida Hedw. (Bryophyta, Tetraphidaceae) is necessary as, two original Hedwig herbarium sheets, containing multiple stems, are present in theHedwig-Schwagrichen collection housed in G. Protologue information and label information do not entirely correspond for either of the herbarium sheets, however a stem of Tetraphis pellucida from one of the two sheets resembles the stem, depicted in Hedwig's original illustration. This stem conforms to the protologue as well as to the modem concept of this taxon and is proposed as the lectotype for this name herein.
