Taxon Profile     (Last Modified On 9/9/2016)
Description : Plants 60–150 mm high. Corm ± ovoid, asymmetric, obliquely flattened below; tunics brown, concentric, drawn into points above. Stem often prostrate for a short distance at base, erect above, rarely branched. Leaves 2 or 3, lower 2 basal, prostrate or inclined, much shorter than stem (10–)15–30(–60) mm long, 5–12(–14) mm wide, ovate-oblong, acute or obtuse, sometimes ciliate-pubescent on veins (rarely throughout), frequently minutely brown-pellucid dotted, margins thickened, usually ciliate, often reddish, uppermost inserted on upper part of stem, often entirely sheathing. Spike (1–)2–6-flowered; bracts firm, often brown dotted, 7–10(–12) mm long, inner slightly shorter than outer. Flowers actinomorphic, salver-shaped, white or pale pink above with red marks at tepal bases, dark red (to brown) outside; perianth tube cylindric, 10–18(–30) mm long, well exserted from bracts; tepals spreading, ± elliptic, (7–)10–13 × (3.5–)5–7 mm. Filaments erect, equal, 5–7 mm long; anthers 2–4 mm long, white; pollen white. Style dividing at or near apex of anthers, branches 1.5–2.5 mm long. Capsules globose, 6–8 mm long. Chromosome number 2n = 26. Flowering time: (late July) August to October.
Country : South Africa
South African Province : Western Cape
Distribution and ecology : extending from the Cape Peninsula north to the Olifants River Mtns and east to the Langeberg at Garcias Pass in Western Cape; mainly montane at middle to upper elevations but also at low elevations near the coast, in stony sandstone soils, usually very common after fires.
Diagnosis : easily recognized by the pair of ovate or oblong basal leaves prostrate or nearly so, stem prostrate near base, Geissorhiza ovata has long-tubed white flowers marked with red in the centre and red to brown on the reverse of the tepals. The perianth tube, mostly 10–18 (rarely up to 30) mm, is well exserted from bracts and the spreading tepals are typically 10–13 mm long. It is allied to G. parva, a smaller species with small yellow to creamy-white flowers but a similar habit, short, prostrate or semi-prostrate leaves and smaller flowers, also with a relatively long perianth tube. G. ovata is quite variable as to height and flower size: perianth tube length is typically 10–18 mm long but in plants from the Klein River Mtns the tube is up to 30 mm long. Plants from near the eastern end of its range near Swellendam have the smallest flowers with tepals ± 7 mm long, although the perianth tube is of normal length. None of these variants seems worth taxonomic recognition.
