Recently, a new species ''Tripogon fibrosissimus'' [https://www.ipni.org/a/20046653-1 Landge] & Manoj Chandran<ref name=":0">{{Cite journal|url=https://doi.org/10.11646/phytotaxa.739.2.5|title=Tripogon fibrosissimus (Poaceae: Chloridoideae: Tripogoninae): a new species from the Grand Canyon of India|last1=Landge|first1=Shahid Nawaz|date=28 January 2026|journal=Phytotaxa|issue=2|volume=739|pages=213–226|via=https://www.researchgate.net/publication/400119978_Tripogon_fibrosissimus_Poaceae_Chloridoideae_Tripogoninae_a_new_species_from_the_Grand_Canyon_of_India|last2=Chandran|first2=Manoj|last3=Gude|first3=Alok L.|last4=Shinde|first4=Rajendra D. |doi=10.11646/phytotaxa.739.2.5 |url-access=subscription}}</ref> 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.<ref name=":0" /> It shares striking resemblance with ''Oropetium roxburghianum'' (Schult.) S.M. Phillips.
