The latest phylogenomic tree of a prominent and diverse tribe of Australian Myrtaceae has clarified the evolutionary relationships within this group. With about 800 species, the tribe comprises well-known components of the Australian flora and is also important horticulturally – including featherflowers (Verticordia), waxflowers (Chamelaucium), and Darwinia, to name a few.
This project was associated with the Genomics for Australian Plants initiative which funded the sequencing costs of the project. Several samples were also obtained from the global Plant and Fungal Trees of Life Project led by the Royal Botanic Gardens, Kew.
Our study improved our understanding of the tribe’s deeper phylogenetic relationships and resulted in an additional subtribe (bringing the total to 12). Diversification analyses indicated the tribe also suffered a decline in speciation rates during the Eocene–Oligocene boundary extinction event (c. 34 Ma), a trend similar to that observed across the wider flora.
Our study provides a robust phylogenomic framework for future studies on the tribe, where additional focus on specific subtribes would assist in resolving the taxonomy of many undescribed species in this plant group.

Hallo! Vielen Dank für diesen wirklich klaren und verständlichen Beitrag. Ich stimme voll und ganz zu, was die phylogenomischen Aspekte der australischen Chamelaucieae betrifft. Jetzt, wo ich darüber nachdenke, hätte ich diese Informationen wirklich schon früher gebrauchen können. Es ist faszinierend, wie solche Analysen unser Verständnis von Evolutionsgeschichte und Verwandtschaftsverhältnissen vertiefen können. Was mir besonders gut gefällt, ist die Tiefe der Analyse. Ich würde mir tatsächlich wünschen, noch mehr über die phylogenomics australischer Pflanzen im Allgemeinen zu lesen. Gilt das, was Sie hier beschreiben, Ihrer Meinung nach auch für andere Pflanzenfamilien oder Regionen in Australien? Das wäre eine spannende Frage für weitere Forschung. Insgesamt ist dies einer der besseren Texte, die ich bisher zu diesem Thema gefunden habe. Ich werde…
This post is definitely going into my top resources folder; I've learned so much! The way you explained phylogenomics, especially connecting it to the Australian context, really made it click for me. It’s fascinating how understanding these evolutionary relationships can illuminate so much about biodiversity. I particularly appreciated the section on the Chamelaucieae tribe; it’s a group I hadn’t explored much before. Thinking about my own learning journey, encountering complex scientific fields can feel daunting, but clear explanations like yours make them accessible. It’s also true that having a good mentor can make all the difference when diving into something new. This topic never gets old, especially when it's presented with such clarity and passion. It makes me wonder how…

Really cool to see genomic tools finally clarifying relationships within such a well known but taxonomically messy group. The speciation decline at the Eocene-Oligocene boundary is a fascinating find too. Spotted some related plant systematics content over at https://direwolfseo.co.uk/ that felt very relevant here. Great work from the team.
