- <p><b>Identification key to the <i>Melinis repens</i> aggregate</b></p><p>1. Spikelets (5−) 7−12 mm long. Internode between glumes (0.5−)0.7−1.7(−2) mm long; upper glume and lemma of the lower floret with a long apical beak up to 5.5 mm, the upper glume with prominent ribs and an apical awn 7−14.5 mm long.... <i>M. grandiflora</i></p><p>− Spikelets 2−5 mm long. Internode between glumes 0.1−0.8 mm long; upper glume and lemma of the lower floret with a short apical beak up to 2.5 mm long or beakless, the upper glume submuticous or with an apical awn up to 7 mm long.........................2</p><p>2. Hairs of the leaf ligule 0.5−0.8 mm long. Panicle mostly cylindrical, dense, contracted. Internode between glumes (0.5−) 0.6−0.8 mm long; upper glume and lemma of the lower floret cartilaginous to subcoriaceous, with prominent ribs; the upper glume submuticous or with a short apical awn up to 0.1 mm long......................................................................................... <i>M. maroccana</i></p><p>− Hairs of the leaf ligule 0.8−1.6 mm long.
