| The genus Alyxia is revised for Australia and the islands of the Pacific Ocean as the second and final part of a complete revision of the genus. 39 species are recognised for this area of which three are new to science, two are new combinations and one is a new name. 14 species are found in Australia and its offshore territories, 21 species in New Caledonia and the Loyalty Islands, and seven species in the other islands of the Pacific. There is relatively little overlap between regions: two species are found in Malesia and Australia; one species is found in New Guinea and the Solomon Islands; one species in Vanuatu and New Caledonia; and A. stellata is found in Australia, New Caledonia and into the Pacific as far as Hawaii and Henderson Island.

| Whilst examining the specimens of Apocynaceae in Herbarium Bogoriense I came upon two unknown specimens which appeared to be species of Parsonsia. On further examination they turned out to belong to a new genus related to Parsonsia but differing from it in the stamens which are included within the corolla tube and the shape of the corolla, filaments and anthers. This is the second new genus recently discovered in Malesia, the first being Baharuia D.J. Middleton described from plants collected in Borneo and Sumatra. The name of the genus is a somewhat tongue-in-cheek reference to the funding for my work on Malesian Apocynaceae, the European Currency Unit or ECU. The genus was launched during the opening of the Van Steenis Building by Her Majesty Queen... |
