Perillemenoa

Perillemenoa is a hypothetical genus used in teaching and in speculative fiction to illustrate principles of plant taxonomy and nomenclature. It is not recognized by current taxonomic authorities and is generally treated as a placeholder in educational materials.

Classification and description: In illustrative frameworks, Perillemenoa is presented as a monotypic genus placed in the imaginary family Perillemenaceae. The sole species is Perillemenoa exemplaris. In such contexts, the plant is described as an evergreen shrub with opposite leaves, small bell-shaped flowers in loose panicles, and a dry capsule as fruit. The imagined distribution is a tropical montane environment on a fictional archipelago, chosen to demonstrate how geography can influence a genus’s perceived diversity.

Etymology and usage: The name Perillemenoa is a coined term created to resemble genuine taxonomic names, combining elements from classical-language roots. It is used primarily to explain conventions around genus naming, type species designation, and the construction of binomials.

Educational and cultural role: Perillemenoa is commonly found in textbooks, classroom exercises, and some science fiction worlds as a clear example of a monotypic genus and of how placeholder taxa are used in teaching about taxonomy, phylogeny, and nomenclatural rules.
