The generic limits of Ixodia R.Br. ex Ait. (Compositae-Inuleae).

Abstract

The two Tasmanian species of Ixodia (I. angusta and I. achlaena) are re-examined in relation to Ixodia achillaeoides, Haeckeria, Cassinia, Helichrysum and Ammobium. It is concluded that they show as great, if not more, similarity to Haeckeria and Cassinia (especially sect. Rhynea) as they do to Ixodia achillaeoides, and it is proposed that they be segregated as a new genus Odixia. Two new combinations are made: Odixia angusta and 0. achlaena.
