jungia

Jungia is a genus of flowering plants in the family Asteraceae, native to the Andean region of South America. The genus comprises several dozen species of herbaceous perennials and small shrubs. Members of Jungia vary in size and foliage, but most have simple leaves and flower heads typical of the Asteraceae.

Taxonomy and name: The name Jungia honors botanists who studied Andean flora. In traditional classifications, Jungia is placed within the subfamily Asteroideae. Its tribal assignment has varied among taxonomists, with several analyses placing it in Heliantheae sensu lato or Eupatorieae, depending on morphological and molecular evidence.

Description: Jungia plants are generally herbaceous or subshrubs. Leaves are opposite or alternately arranged, and the inflorescences are capitula that produce clusters of small florets. Flower color ranges from yellow to orange in many species, though purplish and white forms are known in some groups. The fruits are small achenes with a pappus that aids wind dispersal.

Distribution and habitat: The genus is most diverse in the Andean highlands, from Colombia and Ecuador through Peru and Bolivia to parts of Argentina and Chile. Species occupy montane forests, grasslands, and páramo ecosystems, often at elevated altitudes and in cool, humid microclimates.

Ecology and uses: Jungia species are insect-pollinated and contribute to local pollination networks. They are cultivated occasionally as ornamentals in temperate gardens and display gardens in their native range, and some species are collected for traditional uses. Conservation status varies by species, with habitat loss and climate change affecting several but not all taxa. Taxonomic revisions are ongoing as molecular studies refine relationships within Asteraceae.
