Eulophia is a genus in the Orchidaceae family with over 200 species spread throughout tropical Americas, Asia and South Africa. They are characterized by being terrestrial, rarely epiphytic and are tall having globose corms, short stalks and long plicate leaves. The inflorescence is basal and can attain a length of 15' (5 meters) with a raceme of several, medium sized flowers with lateral sepals that arch upwards, a lip that is deeply concave at the base and carries longitudinal crests on its blade. There is a long foot on the column carrying two pollina with a stipe.
