Daviesia wyattiana, commonly known as long-leaf bitter-pea,[2] is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia.

It is a sparse, erect shrub with long, linear phyllodes, and groups of four to seven yellow flowers with red or purplish markings.

Flowering occurs from August to November and the fruit is a triangular pod 7–10 mm (0.28–0.39 in) long.

[2][3][4][5] Daviesia wyattiana was first formally described in 1880 by Frederick Manson Bailey in the journal, The Garden and The Field: A Journal of General Industries, from a specimen he found "growing among rocks at the Eight-mile Plain, a locality to the south of Brisbane".

[7] Long-leaf bitter-pea usually grows in forest on rocky ridges and occurs from the central ranges of Queensland to near Coffs Harbour, then disjunctly from the Budawangs in southern New South Wales to the far east of Victoria.
