Haemodorum collevatum T.D.Macfarl. & R.L.Barrett APNI*

Description: Plant 65–135 cm tall. Bulb to 25 mm diameter, 6–21 cm below the soil surface, dark orange.

Basal leaves 4–6; lamina linear, flat, 350–1060 mm long, 1.5–6(–7) mm wide. Leaves on scape 3 or 4(5), green, transitioning to glaucous-green bracts, lowest bract to 210 mm long.

Inflorescence one (rarely 2) per plant, paniculate; scape 620–1310 mm long, glaucous-green; flowering portion from lowest major branch 150–450 mm long, with 4–6 primary branches 70–450 mm long, the branches widely spreading at 45–90° from main axis, secondary branching well developed, sometimes repeatedly; flowers in small dense cymose aggregations terminal on the main axis and major and secondary branches, 4–6(–8) in terminal aggregation, 2–4 in branch aggregations; terminal aggregation slightly exceeding, equalling or slightly shorter than those on the branches. Pedicels 6–12 mm long. Bracteoles 2, similar or the lower broader, the texture fairly thick, opaque, without a differentiated broad membranous margin, veins several, obscure; lower bracteole 3.5–8 mm long, narrowly ovate, ovate or obovate, acute; upper bracteole 4.5–7 mm long, ovate to narrowly oblong, acute to obtuse, attached 1.9–3.5 mm below the flower base, the apex at base or to c. 1/4(–1/2) of the flower length. Flowers (10–)11–14 mm long; sepals similar to petals but 1–1.5 mm shorter, narrowly oblong to almost lanceolate, dark brownish, to dark greenish brown towards base; petals 10–13 mm long, dark brownish, sometimes with a purple tint. Stamens equal, enclosed in perianth; filaments 6–7 mm long, yellowish; anthers versatile, 3.2–3.7 mm long, yellow, the tip 2.3–4.1 mm below petal apex. Style (8.5–)10–12 mm long, orange-red at apex, pale green in lower 1/3, longer than the petals by 0.3–1.8 mm; stigma entire, slightly capitate, positioned 3–4.1 mm above the anther tips, exceeding petal tips by 0.3–1.8 mm.

Fruits mid-brown, sometimes with a reddish tint, glossy, 9–14 mm diameter. Seeds black, winged-discoid, 6–7 mm long, 4–5 mm wide.
