Other claims from this paper (11)
- Observation The inferred astelioid phylogeny places Boryaceae outside Blandfordiaceae, then Asteliaceae, then Hypoxidaceae plus Lanariaceae.
- Observation The astelioid crown node was dated to the Late Cretaceous at 75.2 million years.
- Observation An Antarctic-Australasian origin was inferred for astelioids.
- Observation Gondwanan vicariance was not inferred to shape astelioid speciation.
- Mechanism Long-distance dispersal since the Eocene was inferred to account for current astelioid distributions.
- Observation Crown Asteliaceae and Boryaceae had Australian ancestral ranges and diversified since the Eocene.
- Observation Curculigo and Molineria were inferred to have Asian ancestral ranges.
- Observation Diversification of Pauridia and the Curculigo clade occurred steadily.
- Observation Diversification of Astelia and Hypoxis was punctuated over time.
- Association Hypoxis diversification coincided with expansion of African grassland habitat in the Late Miocene.
- Association Astelia diversification coincided with alpine habitat expansion in New Zealand during the Pliocene.
