In Montana, the diversity and abundance of these two tribes of warm season grasses occur mostly in open dry disturbed areas and not commonly in rangeland in good ecological condition. The diversity of this tribe in North America is centered in deserts and seasonally dry or semi-arid woodlands of Mexico and adjacent southwestern USA (e.g., Tamaulipan matorral, Chihuahuan Desert, Sonoran Desert, Mohave Desert, southern Great Basin Desert). Montana harbors relatively few species of Eragrosteae and some very common North American Eragrosteae do not occur in the state.
127. Calamovilfa longifolia.
128. Eragrostis cilianensis.
129. Eragrostis minor.
130. Eragrostis pectinacea. A native annual bunchgrass with mostly erect stems that inhabits disturbed sites, gardens, and cropfields. The inflorescence is an open panicle in fresh condition with many pedicels over 4 mm long. Glandular bumps on lemma veins, inflorescence branches, stem nodes, and leaf margins are not present.

Other Eragrosteae species you should be aware of because they include ornamental cultivars or important range grasses.Eragrostis spectabilis. This species is not in Lesica or the Montana Grasses app. Purple lovegrass. A native perennial bunchgrass with often a very showy purplish open panicle (somewhat similar to the inflorescences of Eragrostis pectinacea), grown as an ornamental, inhabiting disturbed sites usually with sandy substrates, throughout most of southern and eastern USA, Mexico, and Central America.
Blepharoneuron tricholepis. This species is not in Lesica or the Montana Grasses app. Pine dropseed. A native perennial bunchgrass common in the southwestern USA and inhabiting dry open understory, dry meadows, and dry rocky to sandy slopes. Spikelets produce lemmas with three densely hairy lemma veins.
