Commelinales is an order of
raphides. Estimates differ as to when the Commelinales evolved, but most suggest an origin and diversification sometime during the mid- to late Cretaceous. Depending on the methods used, studies suggest a range of origin between 123 and 73 million years, with diversification occurring within the group 110 to 66 million years ago. The order's closest relatives are in the Zingiberales, which includes ginger, bananas, cardamom, and others.[2]
Taxonomy
According to the most recent classification scheme, the APG IV of 2016, the order includes five families:[3]
- Commelinaceae
- Haemodoraceae
- Hanguanaceae
- Philydraceae
- Pontederiaceae
This is unchanged from the APG III of 2009 and the APG II of 2003, but different from the older APG system of 1998, which did not include Hanguanaceae.
Previous classification systems
The older
Mayacaceae, Rapateaceae and Xyridaceae. These families are now known to be only distantly related.[4][1]
In the classification system of superorder Commeliniflorae (also called Commelinanae), and contained five families, of which only Commelinaceae has been retained by the Angiosperm Phylogeny Group
