    Diagnostic Description

    Specimens of K. rotundifolia with dentate leaf margin are easily distinguished from K. crenata by their shorter calyx lobes (up to 2 mm long). A broad concept of K. crenata was adopted here until an opportunity arises to assess the interrelationship between the forms previously identified as K. crenata and K. hirta in more detail. K. hirta is usually a more robust hairy plant up to 1.5 m high which has ovate calyx lobes and occurs in bushveld. Plants up to 0.5 m tall with usually glabrous leaves and linear-triangular calyx lobes have been identified as K. crenata and occur mostly in or near forested areas. Hairy forms of this more delicate form exist (Strey 6706) and R. Fernandes also records such populations from areas in tropical Africa. However, plants from areas north of our region have leaves at least twice as long as broad, except for one cultivated specimen from Zimbabwe which R. Fernandes has referred to as K. hirta. Southern African plants usually have rather broader leaves, whether glabrous or hairy. This and the sporadic occurrence of the hairy form at the northern and southern end of the distribution area with the glabrous form mainly from the areas in between seems to indicate that too much significance has been attached to the hairiness of the leaves. The calyx character also shows some variation and must be investigated in a greater range of specimens. As the species is known only from relatively few collections, population studies are indispensable. Such research should also indicate whether the Southern African material should be recognized as a subspecies separate from the two adopted by R. Fernandes as it has broader leaves and is geographically isolated.

    Morphology

    Sparse shrubs with one to several erect, terete stems up to 1.5 m high. Leaves petiolate, glabrous to hairy; petiole 10-30 mm long, more or less clasping; lamina ovate to oblong, (25-)40-110(-130) x (20-)30-90(-120) mm, obtuse, cuneate to cordate, with blunt teeth rarely doubly dentate or crenate, more or less folded lengthwise, yellowish green to deep-green. Inflorescence a rounded thyrse, usually with many dichasia ending in monochasia. Calyx with lobes narrowly triangular to ovate, 3-5 mm long. Corolla: tube elongate-ampullaceous with long neck, 10-12 mm long, yellow or orange; lobes 3-5 x 1.5-4 mm, orange. Anthers c. 1 mm long. Squamae narrowly oblong, 1.5-2.3 mm long, with rounded apex. Seeds c. 1 mm long.
