The number of stigmas is unknown.
Only a few times collected, probably owing to the fact that the spikelets, all sessile at the very base of the plant, are easily overlooked.
UITTIEN reduced this species to a variety of M. longiflora scarcely deserving recognition. However, it differs from the latter species not only by the lack of a scape, but also by the different structure of the inflorescence, the castaneous base of the leaves, the keeled outer glumes, the winged outermost flower-scales, and the larger nuts.
