The smallest species of the genus, very similar in habit to Paramapania gracillima from the Philippines (see p. 488). Readily distinguishable from this by the longer flowers and glumes, the number of stamens, the linear much longer anthers, the flower-scales not spinulose on the keel, and the different shape of the nut.
