    Stem
    Stem comprising 1 long basal internode to 8 cm. long, usually reaching to just below ground-level, upper internodes contracted, rarely 5-10 mm. long, the aerial stem 2-5(-10) cm. long; simple or with several branches, each subtended by leaves or by leafy bracts.
    Inflorescences
    Inflorescence comprising 1 or more congested spikes, ± umbellate in appearance, flowers 3-6 per branch; bracts herbaceous, lanceolate, 6-15 cm. long, the outer lightly corrugate, the inner ± 1/3 shorter than the outer, ± membranous.
    Flowers
    Flowers actinomorphic, hypocrateriform, white to ivory, usually strongly scented especially in the evenings; perianth-tube cylindric, 10-14 cm. long; tepals narrowly lanceolate, attenuate, 3.5-4 cm. long, extended horizontally or sometimes slightly drooping, widest in the lower 1/3 and there 4-5 mm. wide.
    Stamens
    Filaments ± 4 mm. long, exserted for 1.5-2 mm.; anthers 6-8 mm. long, white.
    Style
    Style usually reaching to ± the anther-apices, sometimes shorter, branches 3-4 mm. long, forked for ± 1/2 their length.

    Corms
    Corms 15–20 mm in diameter at the base; tunics brown, woody, the outer breaking irregularly, rarely becoming fibrous when decayed.
    Leaves
    Leaves few, often only 2, usually very similar to the bracts and differing mainly by their position, the lowermost inserted below the ground, and up to twice as long as the bracts, up to 30 cm long and 3–5 mm wide, linear, plicate.
    Stem
    Stem basal internode up to 8 cm long, usually arising from just below ground level, the upper internodes contracted, rarely 5–10 mm long; the aerial stem 2–5(10) cm long, simple or with a few short branches.
    Inflorescences
    Inflorescence of 1 or more congested spikes, more or less umbellate in appearance, flowers 3–6 per branch; the outer bracts green, 6–15 cm long, lanceolate, lightly plicate, the inner bracts about one-third shorter than the outer and more or less membranous.
    Flowers
