Taxon Profile     (Last Modified On 12/31/2016)
Description: Plants 70–180 mm high. Corm depressed-globose, 10–14 mm diam., producing slender white stolons from base; tunics membranous to papery, not accumulating. Stem ± erect below, flexed outward and inclined in middle, rarely with short branch. Leaves 3, overlapping, lowermost longest, ± as long or slightly longer than stem, plane, somwhat fleshy, falcate, 3–6(–9) mm wide, main and 1 or 2 secondary veins evident but not thickened, remaining leaves reaching to between middle of stem and base of spike, uppermost usually mostly channeled. Spike flexed at base, inclined, 1–3-flowered, lightly flexuose; bracts green, outer 20–25 mm long, margins transparent, inner shorter and ± enclosed by outer. Flowers purple-pink but paler distally with strong purple to green veining, lower tepals with dark yellow-green band shortly below apex, sometimes purple veined at tips, strongly and sweetly scented; perianth tube narrowly and obliquely funnel-shaped, 10–12 mm long; tepals with dorsal longest, straight and erect, oblanceolate, 28–35 mm long, widest in upper 1/3 with margins recurved, upper laterals spade-shaped, bases abruptly narrowed and claw-like for 2–3 mm, limbs triangular, acute, curving outward in upper 1/2, 15–18 mm long, lower 3 tepals joined to upper laterals for ± 1 mm and together for ± 1 mm, free for ± 15 mm long, clawed and narrow and channeled below, abruptly expanded into limbs 8–9 mm long, sutures between lower and upper lateral tepals thickened into iridescent papillose ridges. Filaments strongly arched, 20–25 mm long, exserted 18–20 mm from tube; anthers 6–8 mm long, purple; pollen yellow. Style arched over the filaments, dividing opposite upper third of anthers, branches 5–6 mm long. Capsules obovoid with rounded apices, obscurely 3-lobed, 12–18 mm long. Seeds round to broadly oval, ± 6 × 4–5 mm, broadly and evenly winged. Flowering time: mid August to the end of September.
Country: South Africa
South African Province: Northern Cape, Western Cape
Distribution and ecology: restricted to the southwestern interior, from the Bokkeveld Escarpment and Hantam to the Roggeveld and Klein Roggeveld in Northern Cape and though the northern Cederberg, Tanqua Karoo basin to Touws River in Western Cape; on clay soils in renosterveld and succulant shrubland, forming extensive clonies through vegetative reproduction via stolons.
Diagnosis: recognized by the short stature, rarely exceeding 150 mm, plane, subsucculent and usually ± falcate leaves, and the strongly purple-veined flowers with a large, suberect dorsal tepal. The production of slender, naked stolons is characteristic for the species. Gladiolus ceresianus and G. virescens have similar flowers but corrugate or grooved to terete leaves with thickened and raised veins and margins, and sessile or subsessile cormlets.
