Vernoniopsis Humbert

Jalantzia is a genus of flowering plants in the aster tribe Astereae within the sunflower family Asteraceae. It was previously known as Vernoniopsis Humbert, an illegitimate name. Its species are native to Madagascar.

==Taxonomy== The genus name Vernoniopsis was first used by Per Karl Hjalmar Dusén in 1921. Dusén described one species, Vernoniopsis crassipes, from Brazil, which has since been synonymized with Vernonia plantaginifolia ( treated as either Pycnocephalum plantaginifolium or Chresta plantaginifolia). Dusén's Vernoniopsis is placed in tribe Vernonieae. In 1955, Jean-Henri Humbert used the same name for a new genus, in which he placed a species from Madagascar originally described as Vernonia caudata. Humbert's genus name, being a later homonym, is illegitimate. In 2024, the replacement name Jalantzia was published for Vernoniopsis Humbert. The genus is placed in the tribe Astereae.
