报道江西省种子植物一新记录无叶莲科Petrosaviaceae无叶莲属Petrosavia Beccari疏花无叶莲Petrosavia sakurai (Makino) J. J. Smith ex van Steenis。无叶莲科为江西省新记录科。该种是晚第三纪古热带森林植被的残余种，此次发现于江西井冈山地区笔架山海拔约1200 m的山地常绿阔叶林中，对进一步揭示该地区残存的季雨林植被特征具有重要意义。
The family Petrosaviaceae, containing one genus and one species, i.e. Petrosavia Beccari and Petrosavia sakurai (Makino) J. J. Smith ex van Steenis, was reported as a new record to Jiangxi Province, China. The new record taxon was a residual species that reflected the paleo-climate and tropical paleo-forest at the late tertiary. And it was discovered in the montane evergreen broadleaved forest (elevation 1200 m) in Bijiashan in Jinggangshan Region, which could indicate strongly a remnant property of the monsoon rainforest in Jinggangshan region.
