Blasiaceae

Blasiaceae is a family of liverworts with only two species: Blasia pusilla (a circumboreal species) and Cavicularia densa (found only in Japan).   The family has traditionally been classified among the Metzgeriales, but molecular cladistics suggests a placement at the base of the Marchantiopsida.
