Abstract

The systematic placement of Frullania herzogii has been contentious since its description six decades ago. Over the years it has been interpreted as either a member of the genus Frullania or segregated into its own genus, Neohattoria, due to morphological similarities with both Frullania and Jubula. Here we provide molecular evidence that supports the recognition of the genus Neohattoria and its inclusion within the Jubulaceae, together with Jubula and Nipponolejeunea. Jubulaceae are placed sister to Lejeuneaceae rather than to the monogeneric Frullaniaceae.

Highlights

The liverwort Frullania herzogii S.Hatt. was originally described by Hattori (1955) from a poor, sterile specimen collected on Mt
We investigate whether the genus should be placed in the Frullaniaceae or the Jubulaceae and evaluate whether molecular evidence supports the recognition of Neohattoria as a distinct genus
We worked with two independent datasets to address two different questions, (1) what is the position of Neohattoria relative to the Frullaniaceae, Jubulaceae and Lejeuneaceae, and once we obtained results from these analyses, we asked (2) what is the position of Neohattoria within the Jubulaceae

Summary

Introduction

The liverwort Frullania herzogii S.Hatt. was originally described by Hattori (1955) from a poor, sterile specimen collected on Mt. A few years later, in his monograph of Japanese Frullaniaceae, Kamimura (1961) erected the new genus Hattoria Kamim. To separate this taxon from other Frullania species He stated that his new genus superficially resembled species of Cololejeunea (Spruce) Schiffn. Frullania, there was an important similarity between the branching patterns of Hattoria herzogii (S.Hatt) Kamim. A year later he had to give a new name, Neohattoria Kamim., to his recently described genus (Kamimura 1962), because of the almost simultaneous earlier description of Hattoria by Schuster for a liverwort in the Lophoziaceae (Schuster 1961)
