Facts

  • A climbing vine
  • Shares characteristics with morning glory
  • 45 plants known in 2003

Few and far between

A single specimen of this vine was found in 1985 on Lord Howe Island.

Since then just a handful more have been found in two different habitats, in the northern part of the island on the lower slopes of Dawson’s Ridge, and on Mount Lidgbird in the southern mountains.

On Mount Lidgbird Calystegia affinis grows intermingled with dense Kikuyu and buffalo grasses. Competition for nutrients from the grasses stops it from flowering.

The estimated number of mature plants on Norfolk Island is around 40.

Endemic to Norfolk and Lord Howe islands which are 900 km apart
