Distribution

Indigenous. In New Zealand scattered throughout from the Three Kings and North Island, south to Marlborough in the South Island. Recently (1998) discovered on Norfolk Island

Often found inland on limestone outcrops in the Waikato, and on apatite-rich greywacke rock facies around Wellington and the Wairarapa
