Found in west Kalimantan Borneo alongside rivers in lowland forests as a small sized, hot to warm growing epiphyte with clustered, simple to branching, basal 2 to 3 internodes swollen, forming a 4 angled, fusiform pseudobulb, terete, green in youth, upper internodes becoming brownish green stems carrying deciduous, thin, narrowly elliptic to narrowly lanceolate, midnerve prominent on abaxial side, slightly undulate margins, tapering to a sub-acute, unequally bilobed toothed apex, green sometimes infused with maroon leaves with the basal sheath tightly encircling the stem, narrowly linear, acute, bristle-like mucro opposite the blade, persistent, green soon becoming dirty white sheaths that blooms at most any time of the year on a sessile, arising from the nodes in the upper half of the stem, single flowered inflorescence and carrying a flower that lasts 2 to 3 days.
