Leptotes (plant) are mounted on plaques of vegetal fiber or tree cork. Watering and fertilizer must be more frequent during active growth periods and less during dormant periods. Ideal growth conditions require an intermediate temperature and exposure to filtered sunlight. In April 1833, an unknown species from the Serra dos Órgãos mountains of Brazil blossomed in the greenhouse of Mrs. Arnold Harrison, an English collector of orchids homaged in diverse descriptions of noted species such as "Bifrenaria harrisoniae" and "Cattleya harrisoniana". A short time later, Mrs. Harrison sent a drawing and cutting of this plant to the botanist John Lindley, who verified
Cattleya rex La Paz in Bolivia. It occurs in montane forests and low montane seasonally dry forests at 800–2500 m, growing on tree branches. In its native habitat, flowering occurs between December and March. "Cattleya rex" has been assigned an endangered conservation status in 1997 by the IUCN. Previously believed to be a Peruvian endemic, in 2013 a new locality was reported in Bolivia, thus increasing the area of extension for the species. "C. rex" requires a temperate climate (in winter, artificial heating set at 16 °C at night and 18 °C during the day is recommended) and good ventilation (a dark
