Parahyparrhenia is a genus of Afro-Asian plants in the grass family.[2][3][4][5][6][7] Globally, the genus comprises seven species. Two species are known to occur in India, where they are narrow endemic. The species show disjunct distribution in Africa and Asia. Parahyparrhenia bellariensis (Hack.) Clayton an extremely rare grass which was presumed extinct was rediscovered after the span of 184 years from its type locality in the state of Andhra Pradesh, South India by Mr. Shahid Nawaz, an agrostologist at the Blatter Herbarium .[4] Following its rediscovery, it has been classified as Critically Endangered (CR) by following the guidelines of IUCN Criteria and Category.[4]
Recently, the genus was revised by Shahid Nawaz, an Indian agrostologist, who also reviewed African and Thai species.[5]
