''Ophiopogon'' (lilyturf) is a genus of evergreen perennial plants native to warm temperate to tropical east, southeast, and south Asia.〔〔(Flora of China Vol. 24 Page 252 沿阶草属 yan jie cao shu ''Ophiopogon'' Ker Gawler, Bot. Mag. 27: t. 1063. 1807. )〕 Despite their grasslike appearance, they are not closely related to the true grasses Poaceae. The name of the genus is derived from Greek Όφις ''ophis'', "snake", and πόγὦν ''pogon'', "beard", most probably referring to its leaves and tufted growth.〔Germplasm Resources Information Network: (''Ophiopogon'' )〕〔Flora of China: (''Ophiopogon'' )〕〔Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan ISBN 0-333-47494-5.〕〔When Perennials Bloom: An Almanac for Planning and Planting By Tomasz Aniśko pg 342〕 In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Like many lilioid monocots, it was formerly classified in the Liliaceae. They grow from short rhizomes, and bear tufts of leaves, from which flowers emerge in racemes held on short stems above the leaves. ;Species〔 ==Cultivation and uses== Some species such as ''Ophiopogon japonicus'' and ''Ophiopogon planiscapus'' are used as ground cover plants. In Chinese medicine the tuber of ''Ophiopogon japonicus'', known as mai men dong, is the cardinal herb for yin deficiency. According to the Chinese Herbal Medicine ''Materia Medica'', the herb is sweet, slightly bitter and slightly cold, enters the heart, lung and stomach channels and nourishes the yin of the stomach, spleen, heart and lungs and clears heat and quiets irritability. It is used for hacking dry coughs, dry tongue and mouth and constipation. Liriope (genus) is used as a substitute.〔Bensky, D., Clavey, S., Stoger, E., & Gamble, A. (2004).
