Year: 2013
Type: article
Abstract: The occurrence of 13 species belonging to eight complex thalloid genera and six families are reported for Hunan. Conocephalum japonicum (Thunb.) Grolle, C. salebrosum Szweykowski et al. and Dumortiera hirsuta (Sw.) Nees are moderately common in Hunan, Conocephalum conicum (L.) Dumort., Marchantia palaecea Bertol. and M. emarginata Reinw. et al. subsp. tosana (Steph.) Bischler are rather rare, M. polymorpha L., Plagiochasma pterospermum Mass., Reboulia hemisphaerica (L.) Raddi, and Wiesnerella denutata (Mitt.) Steph. are rare and Asterella khasyana (Griff.) Pandé et al., Plagiochasma appendiculatum Lehm. & Lindenb. and Riccia fluitans L. are very rare. Of them the following are new to Hunan: Genus Plagiochasma with two species, P. appendiculatum, P. pterospermum, Riccia fluitans, Marchantia paleacea and Conocephalum salebrosum. The altitudinal ranges of taxa in Hunan are mapped. The distribution, ecology and the classification of taxa into distributional elements, as well as the characters are discussed. Some thalloid hepatic genera, i.e. Conocephalum and Dumortiera include cryptic taxa that pose unsolved taxonomic problems that await further future research.
