The flowers occur in cymose inflorescences; they have 4âÂÂ7 yellow outer florets with 6âÂÂ8 funnel-shaped disc florets. The fruit has short hairs between brown ribs and is 2.5âÂÂ3 mm long.
The plant is endemic. to AustraliaâÂÂs subtropical Lord Howe Island in the Tasman Sea. It is very rarely collected and apparently restricted to the island localities of Stevens Point and Middle Beach.
