Description

Already dried out here, the flowerheads of Pentzia dentata now contain the dry, single-seeded fruits that do not split open during seed dispersal, still surrounded by rings of involucral bracts. The fruit, a cypsela, is cylindrical, ribbed and yellowish brown.

Each fruit was formed in an ovary where only one ovule developed after flowering into a single seed with pappus attachment (Vlok and Schutte-Vlok, 2015; Bond and Goldblatt, 1984; https://www.encyclopedia.com; http://pza.sanbi.org).
