many-branched, producing dense clumps, compact, slender, ca. 0.6 cm diam., base covered with remains of old leaves;

roots fibrous.

green, extensively branched, forming large clumps, 2–4 cm diam., with pale leaf scars.

simple, solid, 2–4 dm.

2–3-branched, solid, 10–15(–20+) dm.

basal with blade gray-green, usually brilliantly colored basally, drying to unusual gray-green, veins fairly prominent, to 4 dm × 0.7–0.8 cm, often quite glaucous, margins not thickened;

cauline 2–several, spreading, sheathing stem for about 1/2 length, foliaceous, blade not inflated.

basal 4–6, erect, blade bright green, ensiform, 10–13 dm × 2–3 cm, apex slightly curved;

cauline with blade foliaceous, appearing as elongated spathe, 5–6.5 dm × 2–3 cm, not exceeding flowers.

2-flowered;

spathes opposite, connivent, often flushed red basally, broadly lanceolate, 5–9 cm × 6–11 mm, subequal.

2–3-flowered, branch units 1–2-flowered;

spathes tightly enclosing ovary and pedicel, 15–20 cm, subequal;

outer narrowly lanceolate, keeled, margins pale, narrow, inner margins translucent, broad, scarious.

perianth pale creamy yellow with gold or gray veins;

floral tube funnelform, 3–6.2 cm, spreading apically to form wide throat;

sepals horizontally spreading, claw with deep yellow median line, oblanceolate to spatulate, 4.5–7 × 1–2 cm, base gradually attenuate into broad claw;

petals narrowly oblanceolate, 4.3–6 × 0.6–1.4 cm, base gradually attenuate into narrow claw;

ovary elliptical, nearly circular in cross section, 1.5–2.3 cm;

style 2.2–3 cm, crests divergent, linear to narrowly oblong, 1–1.7 cm;

stigmas triangular, margins entire;

pedicel 0.9–2.2 cm at anthesis.

perianth blue or blue-purple;

floral tube tubular-prismatic, 9-ribbed and -grooved, 4–5 cm;

sepals blue or blue-purple with white streaks surrounding signal, oval to orbicular-oval, 9.5–11 × 4–5 cm, base abruptly attenuate into claw, apex obtusely angled, signal with raised, yellow, pubescent central ridge, claw green, striate, 4–4.5 × 1–1.2 cm;

petals erect or spreading-erect, spatulate, 7–8.5 × 2–3 cm, base cuneate, apex emarginate;

ovary bluntly 6-angled, 4–4.5 cm;

style blue-violet, keeled, 3.5–4 cm, raised above sepals, crests recurved, 1.5–2 cm, margins sharply and irregularly serrate;

stigmas 2-lobed with 2 triangular teeth;

pedicel columnar, 3.5–5 cm.

oblong, roundly trigonal, distinctly beaked, 2.5–3.5 cm.

drooping, bright green, ellipsoid, hexagonal in cross section, with 6 broad, rounded lobes, 8–10 × 3 cm, indehiscent;

after anthesis, flower stem elongates, arching downward to push capsule into water, where walls are broken down and as funiculus is broken, seed rises to surface.

dark brown, wrinkled.

in 2 rows per locule, brown, D-shaped, 8–10 mm wide, very corky.
