Taxon Profile     (Last Modified On 11/17/2016)
Description : Plants 0.70–1.1 mm high. Corm subglobose, ± 25 mm diam., producing stolons from base; tunics papery, light brown, becoming fibrous with age. Stem with 2–several well-developed, suberect, ascending branches. Leaves several in basal fan, reaching ± to base of spike, blades sword-shaped, up to 15 mm wide, medium-textured, plane with prominent main vein, often with a pair of secondary veins ± midway between main vein and margins. Spike arching outward, with up to 30 flowers in 2 rows; bracts brown at tips, becoming entirely brown, 4–8 mm long, outer ± acute, inner forked. Flowers zygomorphic, nodding, funnel-shaped, scarlet, often paler outside, yellow in throat, unscented; perianth tube obliquely funnel-shaped, 14–20 mm long, narrow lower part ± 7 mm long, ± abruptly expanded; tepals directed forward, spreading in upper 1/2, dorsal largest, hooded over stamens, 11–15 mm long, lateral and lower tepals 8–12 mm long. Filaments unilateral, 10–12 mm long; anthers parallel, 6–7 mm long, yellow; pollen yellow. Style arching over stamens, dividing opposite anther tips or up to 2 mm beyond them, branches diverging, 2–3 mm long, notched at tips. Capsules ovoid to globose, broadly 3-lobed, 7–8 mm long. Seeds angular-prismatic, up to 8 per locule, 24 per capsule, light to mid-brown, with a spongy coat. Chromosome number 2n = 22. Flowering time: mainly early summer to midsummer (mid-December and January).
Country : South Africa
South African Province : Eastern Cape, KwaZulu-Natal
Distribution and ecology : eastern South Africa and extending from near Umtata in Eastern Cape through KwaZulu-Natal as far north as Melmoth in Zululand; along streams and in light bush along the banks of rivers.
Diagnosis : Crocosmia pottsii may be distinguished by the small, funnel-shaped flowers with a perianth tube 14–20 mm long, and a dorsal tepal up to 15 mm. The leaves are of the ancestral type for the genus: sword-shaped and plane, with a prominent main vein. When Crocosmia pottsii first came to the attention of science it was referred to Montbretia, a genus now included in Tritonia, an African genus of some 30 species. Grown in Scotland in the early 1870s by George H. Potts, who passed specimens on to the Royal Botanic Garden, Edinburgh, where the gardener, James McNab, recorded it in an unpublished list of outdoor plants grown there as ‘Gladiolus pottsii’. Plants of C. pottsii grown at the nursery of Victor Lemoine in Nancy, France were crossed there with the related C. aurea.. The famous interspecific cross between the two made in the late 1870s and the hybrid progeny first flowered in the summer of 1881 and was subsequently called ‘Montbretia crocosmaeflora’, C. ×crocosmiiflora, widespread in gardens in the 20th century and now an unwelcome weed in many parts of the world.
