Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The new genus <italic>Nanooravia</italic> Kiran Raj &amp; Sivad. (Poaceae–Andropogoneae–Dimeriinae) from the southwestern Ghats in India is described and illustrated, and the new combination <italic>N. santapaui</italic> (M. R. Almeida) Kiran Raj &amp; Sivad. is made. The genus is characterized by its usually unequal and intertwined racemes, triquetrous rachis, extremely oblique and glabrous pedicel tip, distantly arranged spikelets, long trigonous callus with oblique tip and densely covered with golden–yellow or yellowish–brown hairs along one angle, keel‐less glumes with a dorsally echinate apex and apically auricled margins, and an upper lemma with a stout awn having a long column. The new genus is distinct from <italic>Dimeria</italic> R. Br. in which the species was originally described, but is similar to the monotypic Indian genus <italic>Pogonachne</italic> Bor currently placed in the subtribe Ischaeminae. It occurs in Peninsular India, a region considered as the centre of diversity of the subtribe with more than 50% of the known <italic>Dimeria</italic> species, including numerous endemics.</p> </abstract>
