Perennials, bulbous herbs; bulbs composed of 1-many fleshey scales, enclosed by a membranous tunics or not. Stems erect, herbaceous; leaves basal or arranged (usually spirally) along stem, glabrous, linear to ovate, bases sheathing, apex sometimes developing into tendril (cirrhose). Infl. terminal, racemose, umbel-like, or reduced to a single flower. Flowers actinomorphic or weakly zygomorphic; tepals 6, usually all similar, free, with basal nectaries. Stamens 6; filaments free. Ovary superior, of 3 locules each with many axile ovules; style simple; stigma simple, 3-lobed or of 3 crests. Fruit a loculicidal capsule.
Differs from Lilium chiefly in its large, heart-shaped, petiolate leaves with dichotomously branched venation. Main bulb dying after flowering, producing many small bulbils. Capsule lobes with prominent, inward-pointing marginal teeth.
Bulb to 10cm diameter; scales few, broadly ovate. Stem 0.9-3(-4)m, massive, to 4.5cm diameter, hollow. Basal leaves in rosette, blade ovate, sub-acute, deeply cordate, to 33(-45) x 24(-40)cm, primary venation pinnate, lateral veins dichotomously branched; petiole to 25cm; stem leaves smaller, more acuminate, less deeply cordate. Infl. a 6-10(-25)-flowered raceme; bracteoles deciduous by flowering; pedicels short (under 1cm). Flowers white tinged greenish outside, streaked reddish or purplish inside (especially inner tepals), sweetly scented, horizontal or deflexed, trumpet-shaped. Tepals narrowly oblanceolate, apex rounded or subacute, reflexed, saccate at base, 11-14.5(-20) x 1.6-2.9cm, inner broader than outer. Filaments 6-7.4cm; anthers purplish-yellow, 0.6-1.5cm. Ovary cylindric, 2.3-3.2cm; stlye pale yellow, 4.5-5.9cm; stigma lobes 3, short, rounded. Capsule segments oblong, to 7 x 3.5cm; seeds reniform, 1-1.5cm, surrounded by very broad membranous wing.
