Anatherum
Upper lemma of the sessile spikelet with an awn 0-6 (-11) mm long; rhizomes well-developed, creeping, with internodes often > 20 mm long; ligule (0.9-) 3.0-4.5 mm long; anthers > 3.8 mm long; inflorescences densely long-villous with white to yellow hairs, the axes somewhat obscured by the density of hairs; [western edge of our area, rarely introduced eastwards]

Chloris
Lemma apices conspicuously bilobed (both the lower bisexual and upper staminate); spikelets pectinate, diverging at a wide angle from branch axes

Digitaria
Plants always with axillary panicles in the lower leaf sheaths (these sometimes concealed by the sheaths); panicles bearing spikelets in groups of 3; lower portions of the pedicels adnate to the axes; leaf blades 3.0-5.0 mm wide; sheaths sometimes sparsely pubescent; [widespread non-native]
