Gilia G. latiflora
Gilia has historically been one of the more enigmatic genera of Polemoniaceae. It is notoriously dificult to key. Recent research has shown that Gilia sensu lato is not monophyletic (this help explain the difficulties with the "genus." Porter and Johnson (2000) have broken the genus formerly known as Gilia up into eight monophyletic genera: Aliciella, Bryantiella, Dayia, Gilia, Giliastrum, Lathrocasis, and Saltugilia; still other species were realigned with Linanthus and Navarretia. Familiar groups that remain in Gilia sensu stricto include the G. capitata lineage, the G. tricolor alliance, and the "cobwebby gilias."
