Species

Angiosperms > Asparagales > Iridaceae > Gladiolus

Characteristics

Capsules obovoid, (1.8-)2-2.4 cm. long.. Plants 40-60 cm. high.. Corm 1.5-2 cm. in diameter, tunics of brittle membranous layers, the outer becoming irregularly broken or fibrous, light brown.. Foliage leaves contemporary with the flowers, 4-5, the lower 2-3 basal or nearly so, laminate, narrowly lanceolate, 5-10 mm. wide, ± 1/3-1/2 as long as the spike, firm textured with moderately raised and thickened midrib and margins, the upper 2-3 leaves cauline and largely or entirely sheathing, often imbricate.. Stem unbranched.. Spike (2-)3-7(-10)-flowered; bracts 2.4-3(-4) cm. long, pale green, evidently becoming dry above, the inner somewhat shorter than the outer.. Flowers pale yellow to cream, the dorsal tepal sometimes flushed with red; perianth-tube 1.8-2.5 cm. long, nearly cylindric below, curving outward and expanded in the upper half; tepals unequal, the 3 upper broadly elliptic-ovate, the dorsal largest, ± (2-)2.5-2.8 × 1.6 cm., hooded over the stamens, the upper laterals ± as long to ± 5 mm. shorter and ± 1.2 cm. wide, directed forward and curving outward distally, the lower 3 tepals 1.2-1.6 cm. long, 7-10 mm. wide, curving downwards, the lowermost somewhat longer than the lower laterals.. Filaments ± 1.6 cm. long, exserted 4-6 mm.; anthers 8-12 mm. long.. Style dividing near the anther-apices, the branches ± 4.5 mm. long.

Flowers pale-yellow to cream-coloured, the uppermost tepal sometimes flushed with red; perianth tube 18–25 mm long, nearly cylindric below, curving outward and expanded in the upper half; tepals unequal, the 3 upper tepals broadly elliptic-ovate, the uppermost (20)25–28 × c. 16 mm, larger than the others and hooded over the stamens, the upper lateral tepals about as long as to c. 5 mm shorter than the upper and c. 12 mm wide, directed forward and curving outward distally, the lower 3 tepals 12–16 × 7–10 mm and down-curved, the lowermost somewhat longer than the lower laterals.
Foliage leaves produced simultaneously with the flowers on the same shoot, 4–5, the lower 2–3 leaves basal or nearly so, about a third to half as long as the spike, 5–10 mm wide and narrowly lanceolate, the blades firm-textured with moderately raised and thickened midrib and margins; the upper 2–3 leaves cauline and largely or entirely sheathing, often imbricate.
