The genus is characterised by its tough raceme rachis bearing strongly compressed single spikelets. It is believed that peninsular India, which has 42 taxa (including 7 infra-specific taxa) and 23 endemic species, is the centre of its distribution.<ref name=":0" /><ref>{{Cite journal |last=Teerawatananon |first=Atchara |last2=Boontia |first2=Veeraya |last3=Chantarasuwan |first3=Bhanumas |last4=Hodkinson |first4=Trevor R. |last5=Sungkaew |first5=Sarawood |date=2014-11-27 |title=A taxonomic revision of the genus Dimeria (Poaceae: Panicoideae) in Thailand |url=https://biotaxa.org/Phytotaxa/article/view/phytotaxa.186.3.2 |journal=Phytotaxa |volume=186 |issue=3 |pages=137 |doi=10.11646/phytotaxa.186.3.2 |issn=1179-3163|url-access=subscription }}</ref>
