Leucospermum cuneiforme is a multistemmed shrub reaching heights from 2 m to 3 m, resprouting from its woody rootstock. The lower stems are warty, bringing the plant the common name of wart-stemmed pincushion.
The hairless leaves are wedge-shaped, ending in three to ten glandular teeth. The leaves become from 4,5 cm to 11 cm long.
The ovoid flowerheads are yellow, fading to reddish orange. The styles are slightly curved and from 38 mm to 55 mm long. The heads are from 5 cm to 9 cm in diameter.
Flowering happens throughout the year, more in spring and summer.
The species distribution is in the Western Cape from Caledon to the Eastern Cape as far as Bathurst and Makhanda.
The habitat is fynbos and renosterveld slopes and flats in sandy or shale soils. The species is not considered to be threatened in its habitat early in the twenty first century (Manning, 2007; Mustart, et al, 1997; Bond and Goldblatt, 1984; iNaturalist; http://redlist.sanbi.org).
