Distribution Vietnam (Quangnam-Danang Province).

Description Rhizome: creeping, mostly subterrestrial, 3 - 9 mm diameter, densely covered with scales; roots thin (< 1 mm diameter), moderately branched, emerging from the rhizome and spreading mostly horizontally to all sides.
Leaves: solitary, quite densely borne on rhizome, to ca. 60 cm; cataphylls 2 - 3, lower ones 2.1 - 4.2 cm, upper one 9 - 11.5 cm, initially purple becoming brown and finally fibrous with further growth of rhizome; petiole 6 - 26 cm; lamina uniformly green, narrowly elliptic to linear, 18 - 33 cm long x 1.2 - 2 cm wide, midvein forming an abaxial prominent keel about 1 mm in height, 3 - 5 prominent secondary longitudinal veins visible on either side, connected more or less regularly every 5 - 7 mm by thin anastomoses, marginal vein absent.

Peduncle: decumbent, ca. 3 cm long, with 4 equidistantly alternating dark purplish violet bracts; flowers solitary.

Perianth [Perigone]: campanulate with subglobose tube, dark purplish violet, not pigmented around base of gynoecium; tube wall up to 1 mm thick, tube 10 mm long x 10 mm diameter (9 mm diameter at throat); lobes 6, triangular, 7 mm long x 5 mm wide, moderately bent outwards (25 - 30°), constricted 3 mm from distal end, resulting in lobe ends appearing rounded.

Stamens: 6, very small (ca. 1.5 mm long x 1.5 mm diameter), subsessile, inserted ca. 3 mm above base, pollen and anthers bright yellowish in colour.

Pistil: ca. 10 mm long x 1.9 mm diameter at thinnest point, style cylindrical, slender, stigma rounded hexagonal, with 6 shallow marginal incisions, surface slightly convex, 4 - 5 mm diameter, white to pale purplish violet; ovary inconspicuous, 2.5 mm diameter.

Fruit: undescribed.

Phenology: flowers end April
