Liverworts and hornworts

These three names fail in three unrelated ways. Marchantia is a person, Nicolas Marchant, so its ch answers to French and its ending answers to Latin. Lunularia is a Latin diminutive with the same vowel in three consecutive syllables. Anthoceros keeps a Greek ending that almost no other genus in a flora bothers with.

Liverworts and hornworts get named less often out loud than mosses do, which makes the heard spellings below rarer and stranger. They are still what people type.
