Common names: Boot protectors (English) Chikada (Shona) Devil thorn (English) Inkunzane (Ndebele) Intekelane (Ndebele) Ruredzo (Shona) Seso (Shona) Soso (Shona) Stud plant (English)
Frequency: Common
Status: Native
Description:
Prostrate perennial with annual creeping stems, occurring almost throughout Zimbabwe. Stems almost hairless or somewhat pubescent. Leaves opposite, usually narrowly ovate in outline, up to 2.7 cm long, often more or less deeply pinnately lobed; margin coarsely crenate-serrate. Flowers solitary, axillary, very pale to deep pink or mauve, usually with darker spots on the lower lip and in the throat. Fruit broadly elliptic in outline, 16-27 mm long, hairless or slightly pubescent, with 2 erect spines on a distinctly raised upper surface.
Notes: Note 1: this species is very similar to D. eriocarpum, which is much more restricted to the sandy soils of western Zimbabwe. That species differs in the smaller, broadly ovate leaves which are never lobed and almost circular fruits, which are densely covered in hairs, particularly when young.

Note 2: The distinctive fruits, armed with a pair of sharp points, which easily penetrate animal hooves, boots and even car tyres, aiding seed dispersal.
Derivation of specific name: senecioides: resembling a Senecio, reference unclear.
Habitat: Favouring bare ground and poor soils and thus forming a good prevention against soil erosion.
Altitude range: (metres) 1470 - 1650 m
Flowering time:Dec - Apr
