Dillwynia is a genus of about 20 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in this genus are shrubs with simple leaves and yellow or red and yellow flowers similar to others in the family.
Description
Plants in the genus Dillwynia are shrubs with simple leaves that are linear, needle-shaped leaves with a groove along the upper surface or triangular in cross-section. The flowers are yellow or red and yellow and usually arranged singly or in small groups in leaf axils or on the ends of branchlets. The upper two of five sepal lobes are joined in a single "lip", the standard petal is broader than long, and the keel is no longer than the wings. The stamens are free from each other, the ovary is on a short stalk and the fruit is a more or less sessile pod.[3][4][5][6]
Taxonomy
The genus Dillwynia was first formally described in 1805 by James Edward Smith in Annals of Botany.[7][8] The name Dillwynia honours Lewis Weston Dillwyn "whose scientific labours respecting the genus Conferva, as well as his knowledge in other abstruse parts of botany, merit such a memorial".[7][8]
