regularius

Regularius is a fictional genus described in the field guides of the Solara desert region within the speculative science-fiction setting Terra Solis. It is distinguished by a highly regular, tessellated pattern of narrow leaves that form a grid-like canopy, a feature that inspired the genus name from the Latin regularis.

Taxonomy and species: Regularius is placed in the fictional family Regularaceae, within the Plantae of Terra Solis. Described species include Regularius rectus (straight-leaf form), Regularius tessellatus (densely tessellated foliage), and Regularius quadratus (square-channeled stems). All species are presented as drought-tolerant, evergreen shrubs reaching roughly 0.5 to 2 meters in height.

Description and morphology: Plants produce slender stems with opposite leaves arranged in regular rows. Leaf blades are narrow to linear, often with a glossy surface to reduce water loss. Reproductive structures consist of small inflorescences that develop into dry seeds. The overall architecture of Regularius colonies tends toward symmetry, a trait noted by biologists and artists within the Terra Solis world.

Distribution and habitat: Regularius is described as endemic to arid plains and rocky outcrops of Solara’s eastern plateau, where rainfall is scarce and soils are sandy loam. It favors microhabitats with morning shade and mineral-rich substrates, often appearing in scattered stands rather than dense thickets.

Etymology and cultural significance: The name Regularius derives from Latin regularis, referring to the orderly morphology of the plants. In Terra Solis fiction, Regularius is cited as an emblem of balance and order and appears in illustrated field guides and related artwork.
