By how much do we underestimate species diversity of liverworts using morphological evidence? An example from Australasian Plagiochila (Plagiochilaceae: Jungermanniopsida)
Species diversity within Australasian Plagiochilaceae is 29% higher than currently recognized. 36% of currently recognized Australasian species have circumscription issues. Integrative taxonomy contributes to resolving robust species hypotheses within a challenging lineage of leafy liverwort.
