Scaevola browniana is a shrub in the family Goodeniaceae, endemic to Western Australia, the Northern Territory and Queensland.
Description
Scaevola browniana is a shrub which grows to a height of 1 m. The leaves lack stalks (sessile), are broadly obovate to oblong, usually entire, and have prominent, silky, axillary hairs. The leaf blades are 6–55 mm long and 2–17 mm wide. The inflorescences are terminal spikes which are up to 20 cm long. The bracts are narrowly lanceolate to narrowly elliptic, 4–25 mm long. The bracteoles are linear to ovate and 4–9 mm long. The blue to white corolla is 5–18 mm long, and has straight silky hairs on the outside, and is bearded on the inside. The ovary is incompletely 2-locular. The cup surrounding the stamen (indusium) is 1–2 mm wide and has hairs on both surfaces. The fruit is cylindrical, wrinkled and free from hair or down. It is 3–5 mm long and usually has one seed.
In Western Australia it flowers from January to October. In the Northern Territory it has been found flowering from January to September, and fruiting in March, May and September.
Scaevola browniana is like S. revoluta but has narrower bracteoles, and lacks of the long ciliate bristles on the bracts and bracteoles.
It has no synonyms.
