Leucospermum calligerum is an erect or sprawling shrub that grows to 2 m in height. The leaves are lanceolate, grey and hairy. Leaf apices rarely have as many as three teeth, usually just a single acute-angled tip. This plant was found in the Elandsberg Nature Reserve at Bartholomeus Klip (Manning, 2009; Bond and Goldblatt, 1984).
