''Leucospermum innovans'' is an upright evergreen shrub with many pustules growing on the lower branches, wedge-shaped leaves, and oval, flower heads that are yellow on the outside, but with scarlet stripes on the inside of the perianth claws, with long styles sticking far beyond the perianths, jointly giving the impression of a pincushion. It is called Pondoland pincushion or Transkei pincushion in English. Flowers occur on and off between July and December, but flowering peaks in September and October.

Differences with related species

''L. innovans'' differs from its close relative ''L. cuneiforme'' because it has very broadly wedge-shaped to inverted egg-shaped leaves, 3–5 cm wide, deeply incised with five to ten teeth near the tip, and the lower, merged part of the

Taxonomy

As far as known, the Pondoland pincushion was first collected for science by a Mr. William Tyson in October 1885. This and later collected plants that are now considered to belong to the Pondoland pincushion were initially identified as ''L. attenuatum'' R.Br. (now '' Leucospermum cuneiforme''). In 1970,

The species is a very resistant to fire, and new shoots appear quickly from the underground rootstock after the above grond parts have been burnt off. Because fires occur with intervals of only a few years, the plants mostly remain lower than , but if protected may reach 1 m. The Pondoland pincushion is pollinated by birds. The fruits are ripe about two months after flowering and fall to the ground. Here, these are collected by ants who carry them to their underground nests.
