A contribution to the knowledge of selected Marchantiaceae taxa in China

ABSTRACT Introduction The family Marchantiaceae is often cited as a representative group of liverworts, partly because Marchantia polymorpha L. is well known as a model plant. Here, we re-examine and provide taxonomic notes on five species of Marchantiaceae in China. Methods Morphological examination was conducted by using dissecting and optical microscopes. Key results Marchantia convoluta was found to be conspecific with M. papillata subsp. grossibarba. Marchantia hartlessiana and M. polymorpha subsp. montivagans are, respectively, added to and excluded from the bryoflora of China. Supplementary descriptions and illustrations are provided for M. subintegra and Preissia platycarpa.
