Abstract
The artesian springs of inland Australia are a unique habitat in what is otherwise an arid environment. They support a rich collection of endemic flora and fauna. Here, morphological and molecular data are employed to describe a new species, Chloris circumfontinalis Fahey & Fensham, endemic to artesian spring systems in central Queensland. A morphological ordination failed to distinguish this species from other Australian native flora, but the shape of the florets distinguishes it from the species with which it co-occurs. Phylogenies estimated from molecular data showed that the species represents a distinct lineage that may be sister to species of Chloris from outside Australia. Chloris circumfontinalis occurs only in the saline scalds that form around the springs, and population surveys at the two sites where it occurs indicated a threat status of Endangered under the IUCN Red List criteria.
