Page "Asparagales" Paragraph 73

The members of this group have a complex taxonomic history, having been assigned to widely differing families in different classification systems.

Proposed subgroups are difficult to recognise, having similar ' lily-like ' flowers, with the result that some members of the group have been included in different subgroups at different times.

Based on phylogenetic research, the latest ( 2009 ) revision of the APG classification supports the use of a single broadly defined family, Asparagaceae sensu lato.

A paper published at the same time as the 2009 classification proposed seven subfamilies for the families recognized in the very first APG classification of 1998.

This division has been used here, although it is not clear whether the approach will be upheld by future research as some of the clades are weakly supported.
