Derantys

Derantys is a genus of flowering plants in the Amaranthaceae family. It is native to warm temperate and subtropical regions and includes several described species. The genus was recognized as a distinct lineage in modern botanical literature in the late 20th century. Derantys species are typically herbaceous perennials or small shrubs, with slender to woody stems and simple, alternately arranged leaves. The inflorescences are dense panicles bearing numerous small, inconspicuous flowers. Flowers usually lack showy petals; the perianth is reduced, and the calyx or bracts subtend a dry capsule fruit. Seeds are small, often dark and glossy.

Distribution and habitat: Derantys is found in dry and open habitats, including grasslands, scrublands, and rocky slopes, in parts of southern Europe, North Africa, the Middle East, and adjacent regions. They are adapted to arid and semi-arid climates and are tolerant of poor soils and drought.

Ecology and uses: Pollination is primarily wind-driven; seeds are dispersed by gravity and, in some species, by small animals. Several species are grown as ornamental plants in drought-tolerant gardens due to their unremarkable flowers and foliage and late-season resilience. In horticulture, they are valued for low maintenance and resistance to heat.

Taxonomy and phylogeny: Derantys is placed in Amaranthaceae, a family that includes many drought-tolerant taxa. It is part of a clade characterized by reduced flowers and dry fruits. Ongoing molecular studies aim to resolve relationships with closely related genera.

Conservation: Habitat loss and climate change threaten certain Derantys species with range restriction. Some populations persist in protected areas and in agricultural margins where they co-occur with other drought-adapted flora.
