sisepinnaga

Sisepinnaga is a fictional plant genus used in world-building and speculative botany. In the imagined biogeography of the Nerean Archipelago, sisepinnaga is a monotypic genus containing the species Sisepinnaga pinnata.

Taxonomy and morphology: It is placed in the fictional family Pinnaceae within the Rosales-like order used in this setting. The sole species, Sisepinnaga pinnata, grows as a woody shrub up to 2 meters tall. Leaves are pinnate with 3–7 leaflets, glossy and dark green. The inflorescence is a terminal panicle of small pinkish-white flowers. The fruit is a winged capsule that disperses seeds by wind and water.

Distribution and habitat: Sisepinnaga pinnata is described as endemic to the coastal belt of the southern Nerean islands, occupying mangrove fringes and brackish wetlands from sea level to about 30 meters elevation.

Ecology and uses: Pollination is by small bees and wind. Seeds disperse by wind and tidal flow. The plant helps stabilize banks and provides microhabitats for insects. In fictional ethnobotanical records, leaf extracts are cited in traditional anti-inflammatory remedies; wood is used for small crafts.

Etymology and taxonomy notes: The genus name is derived from local terms for shade and leaf structure, while the species epithet pinnata refers to the pinnate leaf form. The genus is described by botanist A. N. Mendez in 1989 in the in-world flora compendium.
