Zygopetalum (Hook. 1833), is a genus of the orchid family (Orchidaceae) (subfamily Epidendroideae, tribe Maxillarieae, subtribe Zygopetalinae), consisting of fourteen currently recognized species.〔(Kew World Checklist of Selected Plant Families )〕〔Pridgeon, A.M., Cribb, P.J., Chase, M.C. & Rasmussen, F.N. (2009). Epidendroideae (Part two). Genera Orchidacearum 5: 1-585. Oxford University Press, New York, Oxford.〕 This orchid's generic name, derived from the Greek word "zygon", means "yoked petal." It refers to the yoke-like growth at the base of the lip caused by the fusion of petals and the sepals. They occur in humid forests at low- to mid-elevation regions of South America, with most species in Brazil.〔 Most are epiphytes, but some are terrestrials with glossy, strap-like, plicate leaves, which are apical, oblong or elliptic-lanceolate, acute or acuminate. These orchids have a robust growth form. Their ovoid-conical pseudobulbs are deciduous. They produce an erect, 60 centimeter-long, few-flowered to several-flowered, racemose inflorescence that grows laterally and is longer than the leaves. Their prominent bracts equal the length of the ovary. They are known for their fragrant, waxy, and long-lived flowers with multiple blooms in shades of green, purple, burgundy, and raspberry with several patterns. They are known for their ease of culture and are much in demand as excellent cut flowers. == Species == Species accepted as of June 2014:〔 # ''Zygopetalum brachypetalum'' Lindl. - Brazil # ''Zygopetalum crinitum'' G.Lodd. - Brazil # ''Zygopetalum ghillanyi'' Pabst - São Paulo # ''Zygopetalum graminifolium'' Rolfe - São Paulo, Rio de Janeiro # ''Zygopetalum maculatum'' (Kunth) Garay - Spotted Zygopetalum - Peru, Bolivia, Brazil # ''Zygopetalum maxillare'' G.Lodd. - Brazil, Paraguay, Argentina # ''Zygopetalum microphytum'' Barb.Rodr. - Minas Gerais, São Paulo # ''Zygopetalum pabstii'' Toscano - Espírito Santo # ''Zygopetalum pedicellatum'' (Sw.)
