In that system, which differed only in minor detail from 1964 (which see) he placed Lilianae together with Juncanae as superorders of the subclass Liliidae, one of four in class Liliatae ("i.e." Monocotyledones). Although its composition changed over time, Takhtajan continued its basic structure through to his last work in 2009, in which the Lilianae is one of four superorders of Lillidae. Cronquist developed his system in a rather different way, producing his first overall classification in 1968 (revised 1988), based on subclasses, but not superorders. This placed two orders, Liliales and Orchidales into the subclass Liliidae, and did not contain the Lilianae.
