Information
The salient characters of E. sesamoides are the vegetative stems clad in long (mostly 20-50 mm) ascending leaves and sharply demarcated from the flowering shoots clad in short (c. 4-7 mm) appressed leaves, these leaves normally bract-tipped only immediately below the heads; heads c. 25—27 mm long; involucral bracts pure white, cream, primrose yellow or pink, the outer bracts often partly or wholly pale to dark brown or deep pink, sometimes changing colour with age (e.g. pink when young, pale yellow with age); receptacle with fimbrils much exceeding the ovaries; achenes terete, with conspicuous myxogenic duplex hairs. Fig. 62: 1.
Habitat
Colour variation in the involucral bracts is remarkable and several different colour forms may grow together. Although there is no clear-cut geographical patterning to colour variation, only plants with white, or white faintly tinged pink or brown, bracts have been recorded at the northern and eastern extremes of the range.
Use
1. Edmondia sesamoides (L.) Hilliard in Bot. J. Linn. Soc. 82: 217 (1981). Lectotype: specimen forming basis of Burman, Rar. Afr. PI. 181, t. 67, fig. 2. (G!).
Range
Recorded from the Kamiesberg, then a disjunction to the Koue Bokkeveld, thence south, on the mountains as well as on the flats, to the Cape Peninsula and east to Robinson's Pass and Mossel Bay. Grows in rocky places or in sand, in shrub communities; flowering mainly between September and December. Common. Map 237.
