Pseudobulbs superposed, the new ones arising from about the middle of the previous season’s pseudobulb, often hanging in long chains; each pseudobulb 5–23 cm × 3–6 mm, fusiform, ridged, covered in deciduous leaf bases when young, green or purple, drying yellow, 2–6-leaved.
Lip recurved, 2.3–3 × 2.5 mm, clawed at the base, 3-lobed in the middle; mid-lobe fleshy, 1.3–1.5 × 1.3–1.5 mm, rounded or subquadrate; side lobes suberect, shorter and narrower than the mid-lobe.
