Abstract
Abstract To investigate the evolutionary relationships among species of Afrotrichloris, Apochiton,
Coelachyrum, Dinebra, Eleusine, Leptochloa, and Schoenefeldia of subtribe Eleusininae, a phylogeny based
on DNA sequences from nine gene regions (ITS, rps16‐trnK, rps3, rps16, rpoC2, rpl32‐trnL, ndhF, ndhA, ccsA) is
presented. Previous molecular phylogenies indicated that Coelachyrum was polyphyletic and Schoenefeldia
was paraphyletic, with Afrotrichloris embedded within it. Apochiton burttii was embedded in the Coelachyrum
clade paired with C. longiglume, Coelachyrum poiflorum was placed outside of Coelachyrum and sister to
Eleusine, and Schoenefeldia is paraphyletic, with its two species forming a grade sister to Afrotrichoris. Our
molecular phylogeny supports recognition of a new genus, Schoenefeldiella, and a new combination,
Schoenfeldiella transiens. In addition, we provide generic emendations for Coelachyrum, which now includes
five species including a new combination proposed here, Coelachyrum burttii, and Eleusine, which now
includes 11 species.
