Nolinoideae is a monocot subfamily of the family Asparagaceae in the APG III system of 2009. It was previously treated as a separate family, Ruscaceae s.l.1] The family name is derived from the generic name of the type genus, Nolina.
The subfamily includes genera previously placed in a range of different families, including Ruscaceae s.s., Nolinaceae, Dracaenaceae, Convallariaceae and Eriospermaceae. Like many groups of lilioid monocots, the genera included here were once included in a wide interpretation of the family Liliaceae.
A possibly incomplete list of the genera included in the Agavoideae is given below. The reference is to the source which places the genus in this subfamily. The genera currently included here
have varied widely in their limits and
assignment to families and subfamilies; some former family placements other than Agavaceae which will be found in the literature are given below.
