The genus Haastia has been shown to be polyphyletic and nested in the genus Brachyglottis. There is only low support for this in past phylogenies, however. This study aims to provide greater resolution and support of Haastia’s placement among the sub-tribe Brachyglottidinae. We used more modern Next Generation Sequencing (NGS) techniques to generate a phylogenomic tree of the plastome. The results suggest that Haastia is monophyletic and sister to the core Brachyglottidinae clade, and not nested in Brachyglottis.

Further NGS of the Brachyglottidinae nuclear genome is suggested to provide further evidence for Haastia’s delimitation and to provide greater resolution to other genera also nested in Brachyglottis.
