Geissorhiza callista Goldblatt

Plants 150-350 mm high. Corm ± ovoid, 4-7 mm diam.; tunics ± membranous, not accumulating, light to middle brown, probably imbricate. Stem suberect or inclined, simple or 1-or 2-branched, bearing a sheathing, bract-like leaf in upper 1/3. Leaves 3 or 4(5), lower 2 or 3 ± basal, reaching to ± base of spike, linear to falcate, with thickened margins and main vein, thus 2-grooved on each surface, uppermost leaf cauline, shorter than basal. Spike inclined, flexuose, mostly 3-to 5-flowered, bracts green below, flushed red to purple above, outer 10-13 mm long, inner slightly shorter. Flowers zygomorphic, nodding, with unilateral, declinate stamens and style, deep pink turning dark red-purple at tepal bases, pale in throat; perianth tube ± cylindric, widening near mouth, 22-25 mm long, well exserted from bracts; tepals oblanceolate, 24-26 x 9-12 mm, outer slightly longer than inner. Filaments unequal, unilateral, declinate; two longer 16-20 mm long, shorter one 13-17 mm long; anthers ± erect, ± 4.7 mm long, purple; pollen pale pink. Style arching below filaments, dividing ± 6 mm beyond anthers, branches ± 3 mm long.
