Noun
lilioid (plural lilioids)
(botany) Any of a grade of five monocot orders (Petrosaviales, Dioscoreales, Pandanales, Liliales and Asparagales) in which most species have flowers with relatively large, coloured tepals resembling those of a lily.
Older systems tended to place all lilioid monocots with reticulate veined leaves (such as Smilacaceae and Stemonaceae together with Dioscoraceae) in Dioscoreales. Source: Internet
The order Liliales was very large and had become a used to include almost all monocotyledons with colourful tepals and without starch in their endosperm (the lilioid monocots ). Source: Internet
