Taxon Profile     (Last Modified On 7/5/2016)
Description: Plants 400–650 mm high. Corm 20–30 mm diam.; tunics of wiry, pale, mealy fibres. Stem suberect, sometimes with 1 or more long branches from near base and with short, subsessile lateral branches; upper nodes with sheathing leaves ± as long as spathes. Foliage leaves 2, linear, much longer than stem, suberect, trailing distally, channelled, 6–8 mm wide, margins straight. Rhipidial spathes becoming membranous with fine longitudinal veins, inner 45–60 mm long, outer slightly shorter. Flowers fugaceous, violet, outer tepal limbs with yellow nectar guides at bases, half reflexed; outer tepals 26–29 × 10 mm, claws diverging, ± 10 mm long, inner tepals narrowly lanceolate, suberect, 22–26 × 5 mm. Filaments 5.0–6.5 mm long, united in lower 1/3 to 1/2; anthers 7–8 mm long, violet, pollen yellow. Ovary ± cylindric, 40–55 mm long, fertile in lower ± 12 mm; style branches 9–12 mm long, diverging, crests 7–9 mm long. Capsules and seeds unknown. Chromosome number 2n = 12. Flowering time: October to mid November; opening 16:00–16:30, collapsing after 19:00.
Type specimen: Peter Goldblatt - 4371 - MO - (BC:MO-202566/A:2416811)
Country: South Africa
South African Province: Northern Cape
Distribution and ecology: restricted to the western Karoo and known from less than a handful of sites between Nieuwoudtville and Loeriesfontein in Northern Cape; in heavy red clay in dolerite outcrops.
Diagnosis: one of the tallest and most robust species of sect. Gynandriris, Moraea hesperantha stems may reach up to 650 mm high and bear several, short lateral branches and have two long, suberect, channeled leaves trailing distally. The dark violet flowers recall those of M. pritzeliana but have suberect inner tepals, vs reflexed in M. pritzeliana which has characteristically coiled leaves and is a much shorter plant. M. hesperantha stands out in particular in being evening blooming: the flowers open at 16:00–16:30 p.m., about the time that flowers of M. pritzeliana begin to fade, and the flowers last till well after dark, usually collapsed by 19:30. The evening blooming habit is unique in sect. Gynandriris.
