“…Kellogg () and Soreng et al (2015b) both recognized Aristida, Sartidia , and Stipagrostis in the Aristidoideae and the latter authors retained the tribe Aristideae. Sartidia now includes six species with the description of the Madagascar endemic, S. isaloensis Voronts., Razanatsoa & Besnard, and Aristida includes 305 species with the addition of A. helleriana M. Marchi, J. Mujica & R. L. Barbieri from Rio Grande do Sul, Brazil (Marchi et al, ; Vorontsova et al, ). Morphologically, Aristidoideae can be distinguished from other grasses in having 3‐awned lemmas, a line of hairs for a ligule, 1‐flowered spikelets, lemmas with overlapping margins (involute), and a sharp‐pointed callus (GPWG, ; Cerros‐Tlatilpa et al, ).…”

“…A GenBank DNA sequence for Pentapogon suggests placement in Arundinoideae, but this needs corroboration since its morphology agrees with Poeae. Kellogg (2015) and Soreng et al (2015b) (Marchi et al, 2015;Vorontsova et al, 2015). Morphologically, Aristidoideae can be distinguished from other grasses in having 3-awned lemmas, a line of hairs for a ligule, 1-flowered spikelets, lemmas with overlapping margins (involute), and a sharp-pointed callus (GPWG, 2001;CerrosTlatilpa et al, 2011).…”
