Subterranean tuber globose, solid, smooth, about 0.5 cm in diameter; stems erect, 15.3 cm high, occasionally with a branch or two near the top, glabrous; leaves many, alternately spaced along the whole length of the stem ( with a very slender curved subcapillary petiole 1.0-2.5 cm long; leaf blade, peltately attached, semicircular, with the upper edge straightly or slightly-concave and prolonged at the corners into long acuminate horns, thus giving the blade a semilunate outline, carrying on its adaxial surface numerous long, viscid stipitate glands as in D. burmannii Vahl, the marginal stipitate glands long and spreading and the rest short. Cincinni terminal or lateral, 1-5 cm long, usually 2-8 flowered; flowers white, nearly 1.5 cm across; the individual flowers on pedicels 0.8-1.5 cm long; calyx segments ovate, glabrous but laciniate or ciliate at the margins; petals white, spathulate-obovate; ovary globose; styles 3, fimbriate towards the apex; seeds ovoid, oblong, black.
