Arborea (genus) explained

Arborea is a genus of Petalonamid that was originally considered as being synonymous with Charniodiscus.[1] [2] It consisted of a frond-like body NaNinches long that was attached to the substrate via a Holdfast that possessed many concentric rings on it.[3] Species which were thought to have been within the genus Charniodiscus are now being interpreted as belonging to the genus Arborea with the latter of which being considered synonymous with Charniodiscus.[4] A. arborea was first described from South Australia, and is the most abundant Petalonamid in the Flinders Ranges.[5] The genus currently contains 5 known species with 3 of them originally being species of Charniodiscus; the species include A. arborea, A. denticulata, A. longa, A. oppositus and A. spinosa.[4]
