Taiwanobryum undulatifolium (Neckeraceae), a new combination based on sporophytic features

Abstract

Taiwanobryum undulatifolium (Tixier) W.Z.Ma, Enroth & Shevock is proposed as a new combination, based on the morphological characters of the newly discovered capsules. Lack of cross-striolate ornamentation at the exostome base, long-exserted capsules and mammillose setae are the most important sporophytic characters that support the generic transfer from Neckera. A detailed description and photomicrographs are provided for the sporophyte and perichaetial leaves.

Keywords:
