Taxon Profile     (Last Modified On 6/28/2016)
Description: Plants small, ± 50 mm high. Corm spindle shaped, ± 10 mm diam.; tunics dark brown, very hard, breaking into ± netted fibres. Stem subterranean, with 2–4 ± sessile branches clustered at ground level, with cataphylls pale, becoming fibrous and forming a collar around base. Leaves several, basal longest, 40–60 mm long, linear-filiform, narrowly channelled, rigid, remaining leaves similar but shorter, clustered at ground level. Rhipidial spathes green, 25–30 mm long, inner entirely sheathing, outer somewhat leaf-like, sheathing for ± 5 mm, free distally. Flowers fugaceous, yellow, outer tepal limbs with yellow-orange nectar guides at bases; tepals united in tube 20–30 mm long, outer 23–30 mm long, claw 7–10 mm long, ascending, limb spreading to laxly reflexed, inner tepals 17–22 mm long, also spreading or becoming reflexed. Filaments 5–6 mm, united in lower 1/3; anthers ± 5 mm long, yellow; pollen yellow. Ovary 4–5 mm long, subsessile, included; style branches 10–12 mm long, crests ± 10 mm long. Capsules and seeds unknown. Chromosome number 2n = 20. Flowering time: October.
Country: South Africa
South African Province: Northern Cape
Distribution and ecology: a rare species, recorded only from the Kamiesberg in Namaqualand, Northern Cape; local in moist sandy sites.
Diagnosis: an enigma until 1976, Moraea longiflora was until then known only from a watercolor reproduction of an acaulescent plant with yellow, long-tubed flowers in published Curtis's Botanical Magazine in 1804. The plants, either as seeds or corms were collected circa 1799 by plant collector, James Niven, who had been employed by the English magnate George Hibbert, an enthusiastic grower of Cape plants. The species remained known only from the painting until mid October 1976 when plants were discovered flowering in the Kamiesberg in Namaqualand. The combination of a flower with long perianth tube and underground stem is unique in subg. Umbellatae but the species bears more than a passing resemblance to M. cooperi, which also has a well developed perianth tube, but a well developed aerial stem. The two are most likely closely related and seem well placed in subg. Umbellatae, with which the brown corm tunics and yellow, brown veined tepals and, in M. longiflora, outer rhipidial spathes free and diverging distally, are consistent. Molecular phylogenetic studies place M. longiflora closest to M. margaretae and M. intermedia of subg. Umbellatae whereas M. cooperi is not included in that alliance rendering its relationships uncertain; nevertheless, it has been provisionally assigned to subg. Umbellatae.
