Honey in Scilla, Allium, &c., is secreted by glands in the ovary-wall between the cpls.; in other cases by glands on the bases of the perianth-1. (see Muller's Pert, of Fls.). Yucca (q. v.) has a unique pollination-method. Economically the L. are of no great value. The chief food plants are Alli- um and Asparagus; Phormium, Yucca, and Sansevieria yield useful fibre; Smilax, Urginea, Aloe, Colchicum, Veratrum, &c., are medicinal. Xanthorrhoea and Dracaena yield resins; Chlorogalum is used as soap. Many are favourite garden and greenhouse plants, Convallaria, Tulipa, Fritillaria, Lilium, Agapanthus, Kniphofia, Funkia, Hyacinthus, Gloriosa, and many more. Classification and chief genera (after Engler): the L. are closely allied to Juncaceae; usu. they can be distinguished by their petaloid P, but many L. have a sepaloid P, Xanthorrhoea, Kingia, &c., and in these cases almost the only distinction is the absence in L. of the long thread-like twisted stigmas of J. BH. unite these genera, and some others, to Juncaceae, and place sub-fams. vin and ix in Haemodoraceae. Warming splits up the family into Colchicaceae, Liliaceae, and Convallariaceae
