Goodeniaceae is a family of flowering plants in the order Asterales. It contains about 404 species [3] in twelve genera. The family is distributed mostly in Australia, except for the genus Scaevola , which is pantropical. Its species are found across most of Australia, being especially common in arid and semi-arid climates.

Morphology

Species in Goodeniaceae are generally herbaceous with spiral leaves. Flowers have a single plane of symmetry (monosymmetric; Brunonia being the sole exception), and are either fan-like (e.g., Scaevola ) or bilabiate (as in Dampiera ). Corolla lobes often have two thin marginal wings, which also occur in other families of Asterales such as the Menyanthaceae and Argophyllaceae. The style bears a pollen-cup, also known as an indusium, at the tip, a unique character for the family. The indusium has a function in secondary pollen presentation, a phenomenon also occurring in the related families Asteraceae and Campanulaceae. The ovary is inferior and the fruit is a drupe, a nut or a capsule. The seeds from capsular fruits usually have a mucilaginous wing.
