Liagoraceae

Liagoraceae is a family of red algae (Rhodophyta) in the order Nemaliales. The type genus is Liagora J.V.Lamouroux. It was originally called Helminthocladiaceae by J.Agardh in 1851, but P. Silva in 1980 stated that this was predated by Liagoraceae which was published in 1843. Various authors over several years, had tried to form tribes within the family, but it was found (each time) that the family is not able to be divided naturally. As the morphological character analyses show too much variation. The family was found to be polyphyletic (having a mixed evolutionary origin) based on analyses of rbcL enzymes. The 2 genera of Yamadaella and Liagoropsis, which were previously placed in the Dermonemataceae family, were found to have independent lineages and could be recognized as two new families Yamadaellaceae and Liagoropsidaceae....read more on Wikipedia.
