Selvenys

Selvenys is a genus of evergreen flowering plants in the family Selvenaceae, native to the temperate forests of the northern hemisphere. The genus contains a small number of species, typically forming low, creeping shrubs or clonal groundcovers.

Leaves are opposite or arranged in whorls, simple, lanceolate to obovate, with a dark green gloss; margins may be serrate. Flowers are small, inconspicuous, typically greenish or pale yellow, produced in dense clusters in spring. Each flower has five petals and a short corolla; pollination is largely by bees and hoverflies. Fruits are dry capsules containing several tiny seeds, dispersed primarily by gravity and short-distance animal movement.

Habitat and distribution: Selvenys species occupy understory zones in deciduous and mixed forests, often on loamy soils with good moisture retention. They range across parts of North America and Eurasia, with higher diversity in montane regions. Some species have narrow distributions and are threatened by deforestation and climate change.

Uses: In horticulture, selvenys are cultivated as shade-tolerant groundcovers or small ornamental shrubs. They are valued for evergreen foliage, late winter-to-spring interest, and ease of maintenance. In research, they are studied for shade-adapted photosynthesis and substrate tolerance.

Etymology: The genus name derives from the Latin selva, meaning forest, combined with -nys, a conventional ending in botanical naming.

Taxonomic note: Selvenys was described in botanical literature in the late 19th century; further revisions have added a handful of species as more forests were surveyed.
