Tripogon is a genus of tropical and subtropical plants in the grass family.[3] They are widespread across Asia, Africa, Australia, and the Americas.[4][5][6][7] Fiveminute grass is a common name for plants in this genus.[8]

Recently, a new species Tripogon fibrosissimus Landge & Manoj Chandran[9] was described from Gandikota Hills, a botanically under explored locality in Kadapa district of Andhra Pradesh, South India. The species is characterised by having 2-flowered spikelets and shares morphological similarities with two Afro-Arabian congeners viz., T. africanus (Coss. & Durieu) H. Scholz. & P. Konig and T. oliganthos Cope.[9] It shares striking resemblance with Oropetium roxburghianum (Schult.) S.M. Phillips.
