This Serruria flowerhead photographed in the Hermanus area would have been posted as Serruria rostellaris if the triangular to lanceolate bracts did not spread so consistently. In S. rostellaris the red purple bracts are more erect, encircling the flowerhead base.
The head in picture may be stalkless or near that. The white perianths curve, the styles hard to see. The yellow green, dissected leaves have fine points. The stems are reddish (Manning, 2007; Rebelo, 1995; iNaturalist).
