'', '' Donatia novae-zelandiae'' and ''Mitrasacme archeri''. This undulating mat of mixed species is referred to as mosaic cushion heath. The leaves of ''D. minimum'' are bright green and sessile, with reddish tips and a broad sheathing base as long as the blade, approx . The flowers are small, solitary, white, and tubular, sitting directly on top of the foliage. The plant can often be mistaken for the vegetatively similar cushion plants ''Abrotanella forsterioides'' and ''Donatia novae-zelandieae'', however ''D. minimum'' is distinguished by its lack of a hairpoint on the leaf tip or hairy leaf axils. Cuchion plants are extremely slow growing and can occupy sites for a long period of time.
