The small flowerheads of Gymnodiscus capillaris grow in loose, nearly flat-topped, corymb-like clusters on sparsely branched stems. One plant may produce several stems bringing about profuse flowering.

The yellow, female ray florets are short and oblong with rounded tips. They spread when open, surrounding the small disc of deep yellow male florets that have five-lobed corollas and oblong anthers. Open flowerheads are up to 8 mm in diameter.

In picture the single row of pointed, green, involucral bracts fold in and the rays above them are curled up for some reason, maybe the absence of sunlight. Flowering happens from before midwinter to early spring.

The generic name, Gymnodiscus, is derived from the Greek words gymnos meaning naked and diskos meaning a round plate or quoit, referring to the nude receptacle, the base of the flowerhead. 

The specific name, capillaris, is derived from the Latin words capillus meaning the hair of the head or a hair and -aris meaning pertaining to, referring to some hair-like feature of the hairless plant (Le Roux, et al, 2005; Leistner, (Ed.), 2000; Andrew, 2017; iNaturalist).
