Recent advance on study of Pleuromeia

Pleuromeia is an Early-Middle Triassic index lycopod plant, very significant for study of floral age, paleoecology and paleogeography. In recent years, the progresses in the study of Pleuromeia include the new taxon Pleuromeia shaolinii Zhang et Wang found from the Middle Triassic Lianjia flora in Benxi, China; and a new strobilus of Pleuromeia found from the Lower Triassic of Nevada, USA. Four species of Pleuromeia were selected by Mendelin et al. (2022) as the iconic taxa for four ages from the Lower to Middle Triassic in the world (including the Chinese species P. shaolinii), which is more significant for paleogeographic and evolutionary studies of Pleuromeia.
