The Angiosperm Phylogeny Group 's 2009 classification classification places Agavaceae , along with a number of other families ( including Ruscaceae ) in an expanded family Asparagaceae , rejecting the alternative of keeping some of the families separate , as was permitted in their earlier 2003 proposal . Members of the APG have proposed the subfamily Agavoidae as a replacement for the old Agavaceae .
