Taxonomy

The genus was named in 1824 by John Lindley after horticulturalist

William Cattley William Cattley (1788 – 8 August 1835) was a British merchant and horticulturist. He was significantly involved with the trade between Britain and Russia, including the importation of grain (generically called "corn") to England. He also ...

'' from William Swainson who had discovered the new plant in Pernambuco, Brazil, in 1817. The plant successfully bloomed under the care of Cattley and it became the type specimen from which Lindley described ''C. labiata''.

Cultivation

* ''Light'' :Cattleyas need light, but not direct sunlight; in case of intense sunlight, shade must be provided. * ''Temperature'' :Day temperatures must be between 25-30 °C (77-86 °F) and night temperatures not lower than 10-12 °C (50-53.6 °F). * ''Humidity'' :Must be between 40-70% with good ventilation; however plants must not be exposed to air currents. * ''Watering'' :Water only if substrate is dry. It can be done once a week, but it all depends on the environmental conditions and the season. * ''Fertilizing'' :Cattleyas can survive without fertilizing. However, it is advisable to use nitrogen-based fertilizers without
