Abstract
Digitaria atra is illustrated for the first time and the original description is emended. The diagnosis of the genus Digitaria is completed by introducing modifications related to the spikelet's morphology and the lower lemma's consistency. Some remarks about the lower palea are included. The unusual morphological characteristics of the spikelet of D. atra are compared with the tribe Isachneae and some genera of Paniceae.
