Leaves: leaf sheaths not auriculate, with colorless hairs at summit; blade oblong or lanceolate-oblong to oblong-elliptic, 1.5–6 × 0.4–1.1 cm, margins strongly undulate, completely glabrous or adaxially sparsely pilose. Inflorescences: distal cyme usually exserted, 1-flowered; spathes solitary, pedunculate, strongly inflated, not falcate, 0.7–1.5 × 0.5–0.9 cm, margins connate, often violet, apex acute, sparsely hirsute; peduncles 0.4–1.1 cm. Flowers sometimes cleistogamous and subterranean (not yet seen in our area); chasmogamous flowers bisexual and staminate; petals blue, proximal one very reduced, conspicuous (blue, rather than white or colorless); lateral stamens with filaments laterally compressed and ± winged; antherodes entirely yellow, cruciform. Capsules 3-locular, 2-valved. Seeds sometimes 5, brown, usually only 1 abaxial locule seed developing, enclosed in deciduous, muricate, abaxial capsule valve; seeds of adaxial locule, when present, 2.5 mm, smooth. 2n = 30.
Phenology: Flowering summer–winter.
