Description

The bulging dome of the central Rhynchopsidium pumilum flowerhead disc comprises many tubular, dull yellow florets. Although they appear very different from the elegantly spreading ray florets in a ring around them, when they fruit, the cypselas and pappuses of the two floral forms will look the same.

A cypsela is the small, dry, one-seeded fruit grown from an inferior ovary of some plants in the Asteraceae or daisy family. A pappus is the tuft of hairs or bristles attached to this fruit, facilitating dispersal of the seed by wind.

The (here) dark green, narrow leaves are faintly channelled, acutely pointed and stubbly with glandular hairs (Vlok and Schutte-Vlok, 2015; Manning, 2009; Le Roux, et al, 2005; iNaturalist).
