This remarkable species, like a miniature Pandanus, is distinct from all other species by the non-caudate leaves toothed on the margins and throughout the three main veins. Its nearest ally may be M. graminea UITTIEN from Borneo, in which the spikelets are often also subsessile and trigonous, the texture and nervature of the glumes very similar, and the outermost flower scales also winged.
