D.A.Morrison

Lechenaultia R.Br., Prodr. 581 (1810); named after Jean-Baptiste Louis-Claude-Theodore Leschenault de la Tour (1773–1826), botanist with Nicolas Baudin's expedition to Australia (1800–1804)

Type: Lechenaultia formosa R.Br.

Lechenaultia a. Latouria Endl., Gen. Pl. 508 (1838); Latouria (Endl.) Lindl., Veg. Kingd. 2nd edn, 695 (1847); Lechenaultia sect. Latouria (Endl.) Benth., Fl. Austral. 4: 43 (1868). T: Lechenaultia filiformis R.Br.

Ericopsis C.A.Gardner, J. & Proc. Roy. Soc. W. Australia 9: 42 (1923). T: E. formosus C.A.Gardner.

Perennial herbs or small shrubs, often suckering. Stems several to many, usually glabrous; rootstock woody. Leaves sessile, linear, narrowly lanceolate to ovate, entire, usually glabrous. Inflorescence cymose; flowers sessile; bracts and bracteoles leaf-like, rarely reduced. Sepals linear to narrowly lanceolate, usually glabrous. Corolla bilabiate, usually glabrous outside, hairy inside, red, blue, mauve, white or yellow; free lobes lanceolate, winged. Filaments free; anthers cohering in a tube; pollen grains in tetrads. Ovary inferior, usually erect, 2-locular; ovules numerous, axial; indusium 2-lipped, ciliate. Fruit capsule-like, elongated, retaining outer floral whorls; valves 4, longitudinal. Seeds in articles, with woody endocarp of inner locule wall. x = 9, 18 (6 species) W.J.Peacock, Proc. Linn. Soc. New South Wales 88: 8–27 (1963). 

A genus the Flora of Australia publication listed with 26 species, all occurring in Australia, with one extending to New Guinea; 20 species endemic in south-western W.A. The Australian Plant Census lists 29 species. 

The scientific name is often incorrectly spelt as Leschenaultia , although this spelling is used in vernacular names.
