Notes

Distinguishable from M. tenuiscapa by the much thicker, leathery, transversely wrinkled leaves with only one distinct nerve, the more robust scapes, and the leaves scabrous also on the upper side just below the tail. In appearance it is similar to M. kurzii, but this species has always a capitate inflorescence, with several dark reddish spikelets, almost ribbed glumes, smooth upper side of the leaves, and distinctly winged outermost flower-scales.
The base of the leaf is usually dark brown to almost black, but in the Enggano specimens of a much lighter colour.
