Lambertia is a genus of flowering plants, belonging to the order Proteacea. It is endemic to Australia. The genus was named in 1798 by Sir James Edward Smith in honour of English botanist Aylmer Bourke Lambert.
The Lambertias are sclerophyllous shrubs or small trees. The common name, Wild Honeysuckle, is due to the flowers, which are asymmetrical with a long floral tube and tightly-rolled lobes, in red, orange, yellow and green.
