<p><strong>Two new species of <em>Pterostylis</em> (Orchidaceae; Orchidoideae) from the Sunset Country, Victoria, Australia</strong></p>

In northwestern Victoria, Australia, the Pterostylis (Orchidaceae) section Oligochaetochilus ‘rufa group’ comprises several little studied and poorly collected taxa. We surveyed populations of rufa group in Sunset Country, collecting information on habitat vegetation community. Fourteen sites were for plants with affinities to P. biseta exelsa. measured 23 morphological traits each 31 field-collected seven herbarium specimens from this area. Multivariate analyses undertaken, cluster analysis ordination performed range-standardised data. Three distinct groups present both an dendrogram, key diagnostic characters relating labellum. These compared against other morphologically similar species Pterostylis. Our confirmed one these as biseta, which is widespread two previously undescribed, putatively rare taxa, described here.
