Sphaerocarpales

Sphaerocarpales is an order of plants within the liverworts. Approximately twenty species are in this order which is sub-divided into three families: Sphaerocarpaceae and Riellaceae, as well as the extinct family Naiaditaceae. The inclusion of the Naiaditaceae is uncertain, and the family has sometimes been assigned to the Haplomitriales.
