Tumankalvon

Tumankalvon is a genus of flowering plants in the fictional family Tumankalvaceae. Endemic to the tropical montane forests of the archipelago of Asteros, the genus comprises three described species. Plants in this genus are evergreen shrubs or small trees that typically reach 2–6 meters in height and have thick, glossy leaves arranged oppositely.

The flowers are arranged in loose panicles and feature tubular corollas that are white to pale yellow, often with a contrasting throat. The fruits are dry capsules that split to release several small seeds. The genus is noted for its ornamental appeal, particularly when cultivated in humid, shaded garden settings.

Taxonomy and etymology: Tumankalvon was first described by botanist L. Miro in 2049. The name combines elements drawn from two local terms in the Asteros language family, reflecting forest habitat and seed production.

Distribution and habitat: In the wild, tumankalvon species are found in mid-elevation cloud forests, typically above 1,000 meters, where they form part of mixed evergreen canopy understorey communities. They often associate with ectomycorrhizal fungi and rely on moisture from high humidity and dew.

Conservation: All described species face habitat loss due to deforestation and agricultural expansion. Some populations remain restricted to isolated ridges, leading to vulnerability rankings in regional assessments. Conservation actions emphasize ex situ cultivation, protection of montane forest fragments, and habitat restoration.
