Zocenia

Zocenia is a genus of flowering plants in the family Zoceniaceae. It comprises several species native to montane tropical forests. The genus was established in the botanical literature in the late 20th century and is named after early researchers who studied its members. Zocenia is characterized by herbaceous perennial growth, opposite leaves with simple blades, and inflorescences of dense cymes. The flowers typically have five petals, with a contrasting central column of reproductive organs; corollas are commonly blue to violet, though white forms occur in some species. Fruits are dry capsules containing a few seeds and are dispersed mainly by gravity and short-distance wind.

Distribution and habitat: Zocenia species inhabit cloud and montane forests at elevations roughly between 1,000 and 2,200 meters. They prefer shaded understories and moist, well-drained soils and rely on bee and moth pollinators.

Taxonomy and species: Within the family Zoceniaceae, Zocenia is considered closely related to a small group of genera based on molecular data. Current taxonomic treatments recognize three described species: Zocenia alba, Zocenia rubra, and Zocenia lutea.

Uses and conservation: Zocenia species are primarily of interest as ornamentals in specialist collections and native plant gardens. They are not widely cultivated in commerce. Habitat loss and forest degradation threaten wild populations in some regions, and several species are considered at least locally vulnerable.
