'''''Cymbidium''''' {{IPAc-en|s|ɪ|m|ˈ|b|ɪ|d|i|ə|m}},<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> commonly known as '''boat orchids''', is a [[genus]] of [[evergreen]] [[flowering plant]]s in the orchid [[Family (biology)|family]] [[Orchidaceae]]. Orchids in this genus are [[Epiphyte|epiphytic]], [[Lithophyte|lithophytic]], [[Terrestrial plant|terrestrial]] or rarely leafless [[Saprotrophic nutrition|saprophytic]] [[Herbaceous plant|herbs]] usually with [[pseudobulb]]s. There are usually between three and twelve leaves arranged in two ranks on each pseudobulb or shoot and lasting for several years. From one to a large number of flowers are arranged on an unbranched flowering stem arising from the base of the pseudobulb. The [[sepal]]s and [[petal]]s are all free from and similar to each other. The [[Labellum (botany)|labellum]] is significantly different from the other petals and the sepals and has three lobes. There are about fifty-five species and sixteen further natural [[Hybrid (biology)|hybrids]] occurring in the wild from [[Tropics|tropical]] and [[Subtropics|subtropical]] Asia to Australia. Cymbidiums are well known in horticulture and many [[cultivar]]s have been developed. The genome of ''Cymbidium mannii'' has been sequenced to study epiphytism and [[crassulacean acid metabolism]].<ref>{{Cite journal |last1=Fan |first1=Weishu |last2=He |first2=Zheng-Shan |last3=Zhe |first3=Mengqing |last4=Feng |first4=Jing-Qiu |last5=Zhang |first5=Le |last6=Huang |first6=Yiwei |last7=Liu |first7=Fang |last8=Huang |first8=Jia-Lin |last9=Ya |first9=Ji-Dong |last10=Zhang |first10=Shi-Bao |last11=Yang |first11=Jun-Bo |last12=Zhu |first12=Andan |last13=Li |first13=De-Zhu |date=2023-09-11 |title=High-quality ''Cymbidium mannii'' genome and multifaceted regulation of crassulacean acid metabolism in epiphytes |journal=Plant Communications |series=Focus Issue on Plant Single-Cell Biology |volume=4 |issue=5 |pages=100564 |doi=10.1016/j.xplc.2023.100564 |issn=2590-3462 |pmc=10504564 |pmid=36809882|bibcode=2023PlCom...400564F }}</ref>
