Nepakeiiamus

Nepakeiiamus is a fictional genus of succulent plants described in speculative biogeography and used in educational contexts to illustrate plant taxonomy. It is represented by a single species, Nepakeiiamus aridus, endemic to the arid highlands of the fictional continent of Aridia.

The names Nepakeiiamus derives from Nepakia, a fictional homeland, with the suffix -amus indicating a plant genus in this created system. In this article, the genus is placed in the family Nepakeiaceae, order Nepakeiales, class Magnoliopsida, though the taxonomy is deliberately synthetic for teaching purposes.

Nepakeiiamus aridus is a small, perennial succulent forming compact rosettes. Leaves are firm, narrowly oblanceolate with a waxy cuticle to reduce water loss. Stems are short and angular, bearing solitary peduncles that support tubular magenta flowers about 2.5 cm long. The plant uses CAM photosynthesis, enabling daytime stomatal closure during arid conditions.

It is described as endemic to dry, rocky scrubland at elevations of 900–1800 meters, with an annual rainfall of 250–450 millimeters. Pollination is primarily by native bees; fruiting occurs after seasonal rains, producing dry capsules containing a few wind-dispersed seeds. The species is depicted as drought-tolerant and slow-growing, forming short-lived but resilient populations in disturbed soils.

First described by the fictional botanist L. Verdant in 2145, Nepakeiiamus aridus is a didactic specimen used to demonstrate species concepts such as holotype, synonyms, and conservation status. While not real, the entry illustrates how a genus description is structured in botanical references and how habitat information informs conservation discussions.
