Kia ora, NZ recognises P amoena but Australia treats it as P. phylicifolia (var. ericifolia). On this page NZPCN refers to ITS sequences that differentiate this plant from Australian taxa. Can you refer me to the paper please? Kellerman et al 2005, do not include P. phylicifolia from Australia and the NZ representative in that study is from cultivated material grown in Australia. And I can't find any other sequences in GenBank. Many thanks!
