Corymbium glabrum is a tufted perennial that grows to 60 cm. It is sometimes commonly called plampers, a word of unknown origin.
The Corymbium genus, comprising 9 species that all occur in the fynbos, belongs to the Asteraceae family. These plants produce only disc florets, individually enveloped in bracts and aggregated in corymb-shaped, flat-topped clusters. Each spindle-shaped floret has two rows of bracts and no scales on its receptacle below.
C. glabrum grows in fynbos habitat in sandy soils on rocky slopes at various altitudes and rainfall levels. The distribution in nature ranges from the Cederberg, across the southern coastal and Little Karoo regions to Grahamstown that lies near the eastern end of the fynbos (Manning, 2007; Vlok and Schutte-Vlok, 2010).
