In family-Liliaceae, the leaves are simple, in the form of a cluster of radial leaves, cauline and ramal, exstipulate (but stipulate in Smilax), have parallel venation (but reticulate in Smilax), sessile or petiolate with sheathing leaf base. The inflorescence may be racemose or sometimes solitary (e.g., Tulip, Gloriosa) or umbellate condensed cymes (umbel cyme) eg, onion.
