, a new Australian species in

Nicotiana is found predominantly in the Americas and Australia, but also has representatives Africa Pacific Islands. All native Australian species belong to section Suaveolentes. The number of this uncertain subject revision. An example uncertainty taxonomic status a South accession colloquially termed ‘Corunna’. Here, we report sequences for nuclear plastid markers N. sp. Corunna (D.E.Symon 17088) accessions two other species, burbidgeae benthamiana. Phylogenetic comparison these with those members places all three taxa Suaveolentes shows that ‘Corunna’ represents distinct phylogenetic lineage well supported clade along goodspeedii, maritima, amplexicaulis suaveolentes. Phenetic analysis floral characters supports recognition as which describe here paulineana Newbigin & P.M.Waterh., nov. enlarged molecular dataset described contributes better understanding relationships within section.
