The Leucospermum calligerum stem-tip flowerhead is flattened above rather than globose, the free styles slightly incurving over the whitish mass of collapsed perianth segments in the base.
The common name of pincushion is shared among several Leucospermum species. It refers to the multiple knob-tipped styles standing erect from the flowerheads. The dense mass below them consists of perianth segments with stamens attached, split apart to release the styles.
The ascending, grey-green to yellowish leaves are hairy, ending in reddish tips, often bearing only one hard tooth (Manning, 2009; Bond and Goldblatt, 1984; iNaturalist).
