Notes on Early Land Plants Today 89. Resurrection of Lepidozia parvula (Lepidoziaceae, Marchantiophyta)

Lepidozia parvula N.Kitag. was erroneously treated as a synonym of Lepidozia robusta Steph. in Söderström et al. (2016) due to the unsupported synonymization by Bapna and Kachroo (2000). The taxon has later been recognized (e.g. by Lai et al. 2008; Sukkharak et al. 2008, 2014) and has been reported from a few localities in Thailand. The synonymization must be an error since the two taxa are not at all similar. For instance, Lepidozia parvula has uniseriate leaf lobes (except at the base) while Lepidozia robusta has narrowly triangular leaf lobes. Lepidozia parvula is only known from Thailand while Lepidozia robusta is known from China, Nepal, Bhutan and India, but not from Thailand.
