Notes
E. inamoena closely resembles 31, E. atrovirens, but has a looser panicle with the spikelets evenly distributed, and a shortly rhizomatous base; also, on average, the spikelets are a little larger. At the other end of its range it grades almost imperceptibly into 36, E. chalarothyrsos, in which the spikelets are distinctly ovate.
