It belongs to the Haplotricha subsect. which comprises the species with basal leaves covered by simple setae only. In general appearance, it’s close to O. lanceolata but it’s a different species with narrow stem leaves, larger bracts, shorter pedicels and calyx as well as longer corolla. The geographical distribution of O. vanensis and O. lanceolata are mapped and the identification key for those species is provided. Additionally, diagnostic characters, detailed photographs and habitat descriptions provided along with a vernacular name and IUCN conservation status for O. vanensis.
