Diagnostic Description

Vegetatively the two subspecies are indistinguishable. Florally subsp. mirkinii is usually easily identified by the broader, erect to spreading corolla lobes and the broader corolla tube. In material from around Springbokvlakte the epidermal cells inside the corolla (especially towards the base) are longer and narrower than those seen in subsp. arcuata. Flowers of subsp. mirkinii seem to lack the cream patch in the base of the tube around the corona and are maroon right to the base of the gynostegium. In one collection the corolla lobes were tipped with red as well. The corona is cream in material from Willowmore to near Port Elizabeth but in that from near Pearston it is bright yellow.

Morphology

Corolla campanulate; tube 2.5-5.0 mm long, 5-7 mm broad, broadly cupular; lobes 4-5 mm long, 3-5 mm broad at base, erect to spreading (free at apices), deltate, acute. Corona 1.00-1.25 mm tall, 2.8-4.0 mm broad, cream to bright yellow.
