Species

Angiosperms > Asparagales > Iridaceae > Radinosiphon

Characteristics

Plants (80-)150-500(-750) mm high. Corm 8-15 mm diam., developing scaly rhizomes from base, sometimes producing cormlets; tunics papery, becoming finely fibrous. Stem usually branched, rarely with small cormlet in axils of upper leaves when unbranched. Leaves 6 to 9, mostly basal and reaching base of spike, narrowly lanceolate, 150-300 x 3-10(-15) mm, cauline leaves ± 3, progressively smaller and entirely sheathing. Spike inclined, (2-)4-to 12-flowered; bracts 8-18(-25) mm long. Flowers pale to deep pink, all or only lower 3 tepals with dark pink median streak; perianth tube 15-30 mm long; tepals ± spreading, linear to lanceolate, 8-12(-15) x 1-2(-3), uppermost lanceolate, 2-3 mm wide. Filaments 4-6 mm long, exserted ± 3 mm from tube; anthers 2.5-5.0 mm long, purple. Style dividing opposite or beyond anthers tips, branches 1.5-2.0 mm long. Capsules globose, 4-6 mm long. Seeds 1 or 2 (rarely up to 5 in tropical Africa) per locule, 2-3 mm diam., lightly wrinkled.
