The recommendations of the Angiosperm Phylogeny Group are the international standard 
for plant families and subfamilies, and should be followed. They are based 
on a very detailed survey of all aspects of the plants, chemical, DNA, 
morphology etc, and should not be disregarded because some of their findings 
'seem peculiar'.

Above all, in the world of the monocots, it is essential to throw out the 
old concepts (most especially the once vast Liliaceae) and adopt the idea of 
smaller families with their own particular sets of characteristics, within 
larger lineages, especially the Asparagales and Liliales. The APG website is 
very comprehensive and gives clear cladograms showing relationships between 
families. A list of genera found in each family is given. Do not expect an 
easy read from the site! But use its recommendations!
