New higher taxa of complex thalloid liverworts (Marchantiophyta - Marchantiopsida)

Abstract

Recent studies on molecular phylogeny of complex thalloid liverworts (Marchantiopsida) have revealed the need to recognize four new higher taxa: Family Neohodgsoniaceae, Order Neohodgsoniales, Order Lunulariales and Family Dumortieraceae. These are formally described along with notes on their differences from other complex thalloid liverworts. © Trustees of the Royal Botanic Garden (2006).
