Characteristics

Plants 80-160 mm high. Corm ovoid, symmetric, truncate below, 6-9 mm diam.; tunics blackish, imbricate, notched below into regular sections. Stem erect, flexed above sheath of upper leaf and at base of spike, simple or 1-branched. Leaves 3, lower 2 basal, uppermost inserted on lower part of stem, slightly longer or shorter than stem, linear, 0.5-1.5 mm wide, margins and main vein slightly thickened, thus narrowly 2-grooved on each surface, uppermost leaf with large, inflated, multi-ribbed sheath.

Flowers zygomorphic with stamens unilateral and declinate, tepals widely cupped, deep blue with glossy red centre edged with narrow white band, each tepal with a dark pit in midline; perianth tube funnel-shaped, usually exceeding bracts, 6-8 mm long; tepals obovate, 15-22 x 12-15 mm. Filaments unilateral, declinate, equal, ± 10 mm long, held above lowermost tepal, curving upward distally; anthers erect, ± parallel, 5-6 mm long, dark purple; pollen red-brown. Style arching beneath stamens, ± 2 mm long, branches 4 mm long.
