A re-assessment of the species previously included in Lenormandiopsis including the description of Aneurianna gen. nov. (Rhodomelaceae, Ceramiales)

The genus Lenormandiopsis is a member of the tribe Amansieae characterised by broad foliar blades. In a recent study it was established that the type species of Lenormandiopsis, L. latifolia, conformed to the generic characteristics of the genus Lenormandia, to which it was returned, effectively subsuming the genus Lenormandiopsis within Lenormandia. In the current study, the morphology and anatomy of the remaining species of the former Lenormandiopsis have been examined and found not to share the characteristics of Lenormandia. A new genus, Aneurianna, is established for them, with A. lorentzii as the type species, A. nozawae and the newly described A. dentata. Lenormandiopsis parthasarathyi is found to be conspecific with A. lorentzii. The new genus is distinguished from the remainder of the Amansieae by the foliar blades and endogenous branching, and also by the surface pattern of irregular ellipses.
