Treffailla

Treffailla is a fictional genus of flowering plants created for speculative fiction and worldbuilding. It is described as part of the flora of the Treffa archipelago, a subtropical island group in several collaborative stories. The genus name is presented in-universe as a Latinized construction intended to convey botanical pedigree.

Taxonomy and species: In the fictional taxonomy, Treffailla is placed in the (also fictional) family Treffaillaceae. Noted species include Treffailla alba, with pale, nocturnally fragrant flowers, and Treffailla viridis, which bears luminous green blossoms. Other described species appear in different stories and may vary by author.

Description: Treffailla plants are evergreen shrubs or small trees, typically 1 to 4 meters tall. Leaves are glossy and elliptic; flowers are tubular with three-lobed corollas. Several species are described as having faint bioluminescence or strong scent, especially at dusk.

Habitat and ecology: In-universe habitats include coastal scrub, cloud forests, and garden environments on Treffa's islands. Pollination is attributed to hawkmoths or nocturnal insects, and seeds disperse by wind or splash-dispersal near shorelines. The plants are said to be relatively drought-tolerant once established and capable of thriving in saline spray.

Uses and cultural presence: Treffailla is depicted as an ornamental plant and is cited for essential oils used in fictional perfumery and traditional medicine. Its imagery is used in worldbuilding discussions about island endemism, biogeography, and plant adaptation. The term appears across novels, role-playing games, and art associated with the Treffa setting.
