Banksia vincentia is a shrub that grows in a small location in southern New South Wales.

[2] Local nursery owner Jacki Koppman came across the plant and suspected it was a distinct species, sending material to the New South Wales Herbarium for assessment and identification.

Leaf margins are slightly recurved and densely covered in short hairs.

[4] Banksia vincentia is known from a single population of plants—14 at time of discovery and now down to 12 individual shrubs.

[3] Some of the threats faced by the plant include: impact of road maintenance on highly restricted population, degradation of habitats from increasing urbanization, poor knowledge of the species' distribution and potential abundance, habitat invasion by weeds and invasive grasses, and the presence of Phytophthora cinnamomi which is suspected to have killed several individuals.
