Flowers nodding in cymes of less than ten; petals always blue or pink, never yellow; darkening with age, not changing colour; spring. Fruit becoming glabrous, berrylike; wider at the top, 12-15 mm long.
A species complex under revision.
It is the only naturally occurring blue or pink-flowered Billardiera in E Australia, and is easily distinguished from the introduced Sollya group by the tiny anthers much shorter than the filaments.
This species is becoming a weedy pest in the Australian National Bot. Gds, Canberra, and has the potential to spread like Sollya.
For Sollya Group see Sollya.
