Peterson, P M; Romaschenko, K; Barker, N P; Linder, H P (2011). Centropodieae and Ellisochloa, a new tribe and genus in Chloridoideae (Poaceae). Taxon, 60(4):1113-1122.
There has been confusion among taxonomists regarding the subfamilial placement of Merxmuellera papposa, M. rangei, and four species of Centropodia even though many researchers have included them in molecular studies. We conducted a phylogenetic analysis of 127 species using seven plastid regions (rps3, rps16-trnK, rps16, rpl32-trnL, ndhF, ndhA, matK) to infer the evolutionary relationships of Centropodia, M. papposa, and M. rangei with other grasses. Merxmuellera papposa and M. rangei form a clade that is sister to three species of Centropodia, and together they are sister to the remaining tribes in Chloridoideae. We provide the carbon isotope ratios for four species indicating that Merxmuellera papposa and M. rangei are photosynthetically C3, and Centropodia glauca and C. mossamdensis are C4. We present evidence in favor of the expansion of subfamily Chloridoideae to include a new tribe, Centropodieae, which includes two genera, Centropodia and a new genus, Ellisochloa with two species, Ellisochloa papposa and E. rangei. The name Danthonia papposa Nees is lectotypified.
