In India, seven species of the genus Iphigenia exist, with six of them being endemic to the country. The genus is represented by two species in Rajasthan, with a third species, Iphigenia pallida Baker, being reported in this communication as a new addition to the Rajasthan flora. The species had not previously been documented in this area. Senna tora (L.) Roxb., Hyptis suaveolens (L.) Poit., Physalis pruinosa L., Parthenium hysterophorus L., and other invasive species pose the biggest threat to this plant. These invasive plants overshadow this species, develop rapidly, and occupy the plant's habitat. Brief description, key to the whole species, distribution, phenology and photographs are provided to facilitate identification.
