Prostanthera ovalifolia

Prostanthera ovalifolia View in CoL and P. lanceolata

Specimens determined by us a priori in the field or in the herbarium to be P. lanceolata or P. ovalifolia clustered in one group in analyses of morphological and molecular data ( Palsson et al. 2024, fig. 3, 4, Group C), and formed a single clade in our phylogenetic analysis ( Fig. 3 View Fig , Clade B). Given that neither species was recovered as monophyletic (Supplementary Fig. S2 View Fig ), further study of these is warranted. To allow thorough testing of the limits of the species, collection of material from the type location of P. ovalifolia should be a priority. Only the original gathering by Robert Brown exists from this area. The type location is within Shoalwater Military Training Area that has presented obstacles to collection to date. We are again in the process of seeking permission to collect from the site.
