Olevilta

Olevilta is a genus of flowering plants in the family Oleaceae described from the central Andes. As of current knowledge, it comprises a single described species, Olevilta montana, with unconfirmed reports of a second species awaiting formal description.

Description

Olevilta montana is a small evergreen shrub, typically 1 to 2 meters tall. Leaves are opposite, simple, and elliptic, 4 to 8 centimeters long, with a glossy surface. The inflorescences are terminal panicles bearing small tubular flowers with a pale yellow corolla. Fruit is a dark purple drupe about 6 to 8 millimeters in diameter.

Distribution and habitat

The species appears to be endemic to montane cloud forests of the central Andes, at elevations roughly 1800 to 2600 meters. It favors mossy, humid understories but can tolerate drier conditions when established. The region’s climate and mist provide consistent moisture that supports the shrub through extended wet seasons.

Ecology

Olevilta montana is pollinated mainly by bees and hawkmoths, attracted to the pale yellow flowers. Seed dispersal is believed to occur via small frugivorous birds and mammals. The plant tends to establish in partially shaded sites and may show increased vigor in mossy microhabitats.

Taxonomy and etymology

The genus name Olevilta is formed from elements suggesting association with the olive family and high-elevation habitats. The type species is Olevilta montana, described from specimens collected in the Peruvian region near Cusco.

Conservation and use

Restricted distribution and ongoing habitat fragmentation raise conservation concerns. There is no known large-scale commercial use; local communities report traditional uses of plant material in limited medicinal applications. Further field studies are needed to assess population trends and formal conservation status.
