Species

Angiosperms > Asparagales > Iridaceae > Gladiolus

Characteristics

Plants 45-80 cm. high.. Corms 1.5-2.5 cm. in diameter, tunics initially membranous, becoming fibrous and matted with age, fibres brown, enclosing numerous small cormlets.. Leaves four or five, fairly soft-textured, the midrib and margins not thickened, the lower 3 ± basal and longest, lanceolate to linear, reaching to ± the base of the spike, 8-18(-24) mm. wide, the upper 2 leaves cauline and sheathing in the lower half.. Stem unbranched, ± 3 mm. in diameter at the base of the spike.. Spike erect, 5-9-flowered; bracts green and soft-textured, the outer sometimes flushed red, 2.5-4(-6) cm. long, the inner 2/3 as long as the outer.. Flowers bright orange-red or dark red, the lower tepals each with a median white to yellow streak, the marks on the lower laterals spathulate and widest near the tepal apices; perianth-tube 2.5-3.5 cm. long, the lower part slender and cylindric, 1.8-2.5 cm. long, the upper part funnel-shaped, 8-10 mm. long; tepals lanceolate, unequal, the dorsal largest, 4.5-5.5 cm. long, 1.5-3 cm. wide, arched over the stamens and style, the lower 3 united for 1-1.2 cm., ± 4 cm. long, nearly horizontal or tilted toward the ground, in profile the lower equalling or exceeding the dorsal.. Filaments 3.5-4 cm. long, exserted 2-2.5 cm.; anthers 1-1.2 cm. long, reaching to ± the upper 1/3 of the dorsal tepal, with a slender, usually inconspicuous apiculate appendage 0.5-1 mm. long.. Style arched over the stamens, dividing opposite to or beyond the anther-apices, the branches ± 4 mm. long, widened and channelled above.. Capsules ellipsoid, 1.8-2.7 cm. long.
