Characteristics

Plants 60-200(-300) mm high. Stem often branched just above base, branches crowded and ± equal in length, often forming small tufts. Leaves sword-shaped to linear, usually ± as long as stem, sometimes up to twice as long, (2-)3-15(-22) mm wide, mostly subbasal, without visible midrib, often slightly striate, margins often slightly thickened, rarely obscurely crisped, sheaths usually overlapping and concealing stem. Rhipidia 2-flowered; spathes glaucous-green, inner mostly 60-75 mm long, outer slightly shorter to ± as half as long, entirely sheathing or arching outward in distal 1/3. Flowers on pedicels 10-15 mm long; predominantly pale to dull yellowish to pale or mid-brown, or dull grey-blue, limbs with solid dark brown to blackish purple at base, or with scattered dark spots, margins darker or paler in colour, claws uniformly pale or with dark longitudinal streaks or with a broad darker median streak, forming a floral cup 12-15 mm deep, 13-15 mm wide at rim, usually slightly putrid smelling, nectaries usually basal, rarely in pouches in centre of claws, pale or dark coloured; outer tepals 30-40(-45) x 10-15 mm, claws 10-15 mm long; inner tepals 25-40(-45) x 8-10 mm. Filaments united in a column 8-13 mm long, free and arching outward in the upper 2-4 mm; anthers 3.5-5.0 mm long, shorter after dehiscence, thecae joined only at apices, usually widely diverging (rarely almost parallel). Ovary ellipsoid, 15-20 mm long, with sterile beak 5-8 mm long; style branches 2-3 mm long, dividing into diverging, prominently fringed arms, ± 4 mm long; stigmas on small lobes below tips of style arms and arching over anthers. Capsules ellipsoid, 30-50 mm long. Seeds rounded, usually angled by pressure, dull-coloured and lightly wrinkled.
More
Plants usually robust, up to 500 mm high; stem much branched in upper half, sheathed by leaf bases below. Leaves several, linear to sword-shaped, 6-12 mm wide, basal leaves longest with visible main vein. Inflorescences 2-flowered rhipidia; spathes green with membranous margins. Flowers on pedicels 40-60 mm long, lasting a single day, pale yellow to beige with brown to dull purple mottling, strongly scented; tepals widely divergent forming a shallow bowl, limbs spreading horizontally; outer tepals 28-35 mm long, inner tepals slightly shorter and narrower. Ovary spindle-shaped, not beaked; style branches forked in upper half with diverging arms 4-5 mm long prominently fringed; stigmas terminal on style arms. Flowering time Aug.-Oct. Capsule 15-25 mm long, ovoid to oblong. Seeds angular, 5-sided, ± 4 mm long, facets wrinkled.
Cormous geophyte, 60-200 mm tall, often branching close to base. Leaves sword-shaped, crowded basally, without a midrib, margins often lightly thickened, sheaths concealing stem. Flowers dull yellow, yellow-green or light brown, with banded or speckled markings and darker margins, often putrid smelling, claws broad, forming a wide cup, nectaries usually dark, basal, or occasionally large pouches in middle of outer tepal claws, anther lobes diverging. Capsule beaked.
Cormous geophyte, 6-20 cm, branching mostly near base. Leaves sword-shaped, crowded at base, sheathing the stem. Flowers dull yellow, yellow-green or brown, with banded or speckled markings and darker margins, often putrid-smelling, claws broad, forming a wide cup, nectaries usually basal, dark-coloured, anther lobes diverging, capsules beaked.
