This species, which inhabits serpentine soils, is classified within sect. Onosma, subsect. Asterotricha. Morphologically, O. guniae is closely related to O. stenoloba, but it exhibits several distinguishing features, including a shorter stem, longer setose and narrower cauline leaves, longer bracts and pedicels, a different corolla color, shorter filaments, and a distinct nutlet shape and size. The publication provides a comprehensive description of these diagnostic traits, along with original photographs, detailed illustrations, a distribution map, habitat information, an image of the holotype specimen, and an identification key for distinguishing O. guniae from O. stenoloba. Additionally, the vernacular name and the IUCN conservation status of O. guniae are included. %M doi:10.6165/tai.2025.70.301
