Corrigenda — A taxonomic revision of Alstonia (Apocynaceae) in Australia

Abstract

The genus Alstonia R. Br. is revised for Australia. Six species are recognised, namely A. actinophylla (A. Cunn.) Schurnann, A. constricta F. Muell., A. linearis Benth., A. muelleriana Domin, A. scholaris (L.) R. Br. and A. spectabilis R. Br. Two subspecies are recognised for A. spectabilis, with A. ophioxyloides F. Muell. being reduced to subspecific status. A. muelleriana is lectotypified. Generic and specific descriptions, a key to species; notes on variation, distribution, habitat and conservation status are provided. Ethnobotanical use in Australia and adjacent Papuasia is briefly reviewed.
