Bysentra

Bysentra is a fictional plant genus used in world-building and educational examples to illustrate plant taxonomy and morphology. In this construct, bysentra is placed in the family Asteraceae, within the tribe Heliantheae, though it refers to no real species.

The genus currently includes two described species: Bysentra alba and Bysentra viridis. Description: Members are herbaceous perennials with upright stems, opposite leaves, and inflorescences that resemble typical Asteraceae heads, featuring pale blue to violet ray florets surrounding a central disc.

Distribution and habitat: In the fictional ecosystem, bysentra is endemic to the Archipelago of Borealia, occupying coastal scrub, open woodlands, and montane clearings from sea level to about 1200 meters.

Ecology and cultivation: Pollination is by bees and butterflies; seeds disperse by wind. In cultivation, these plants are portrayed as sun-loving, with moderate irrigation and well-drained soil, suitable for ornamental beds and educational displays.

Etymology and usage: The name bysentra is coined for fictional purposes, derived to suggest symmetry and growth.
