The inner surfaces of the innermost Protea parvula involucral bracts are revealed when the flowerhead spreads. These bracts are oblong and channelled, white with pink in the apical regions and irregularly shaped margins. There is the occasional angular tooth and the margin may be finely hair-fringed or ciliate.
The outer rows of bracts are broadly ovate and progressively shorter, often dark-tipped from desiccation.
Some perianths in picture are white, others pink with brown velvety tips that disappear from sight once the pollen presenter breaks free and the segments collapse.
The style is up to 35 mm long, the pollen presenter 5 mm. The four anthers inside the tips of the four segments are up to 8 mm long. The cone-shaped ovary below is about 5 mm long, covered in long, red-brown hairs (Rourke, 1980).
