Heterotaxis sessilis

Heterotaxis sessilis is an epiphytic orchid widespread across the West Indies (Cuba, Hispaniola, Jamaica, Trinidad), Central America (all 7 countries), southern Mexico (Chiapas, Veracruz, Oaxaca, Quintana Roo), Florida and northern South America (Colombia, Ecuador, Peru, northern Brazil, Venezuela, the Guianas). Hidden orchid is a common name.
The species was long called by the synonym "Maxillaria crassifolia" but recent molecular studies have indicated that "Maxillaria" should be split into several genera.
