Rediscovery of Ivania juncalensis Al-Shehbaz (Thelypodieae; Brassicaceae), an endemic and threatened species from the Andes of Central Chile

Abstract

The genus Ivania is endemic to the Andes in Central Chile and comprises two species of range-restricted perennial herbs. Ivania juncalensis was described based on a single herbarium specimen collected in 1976, at a high elevation in the Río Juncal watershed. Given that the population site and status were unknown for more than 30 years, this species was considered potentially extinct. In this article we report the rediscovery of I. juncalensis in the Andes of Valparaiso region. Additionally, we provide an expanded description and new information about its distribution, habitat, ecology, and conservation status.
