The [[monophyly]] of Scilloideae is well supported by studies based on molecular data.<ref name=SebePeteDaviPire12/> These studies also give support to the exclusion of ''[[Camassia]]'', ''[[Chlorogalum]]'' and related genera, i.e. the former Hyacinthaceae subfamily Chlorogaloideae, now placed in the subfamily [[Agavoideae]].<ref name=ChasDuvaHillConr95/>{{sfn|Speta|1998}}

The exact position of the Scilloideae within the broadly defined Asparagaceae is less clear. One possible phylogeny for the seven subfamilies recognised within the family is shown below.<ref name=APweb_Asparagales/>

Although generally agreeing on the main division of the Asparagaceae into two clades, studies have produced slightly different relationships among the Agavoideae, Aphyllanthoideae, Brodiaeoideae and Scilloideae. For example, Seberg et al. (2012) present analyses based on parsimony and on maximum likelihood. In the first, the Scilloideae are sister to the Agavoideae; in the second, they are sister to the Brodiaeoideae.<ref name=SebePeteDaviPire12/>
