Maxillaria crassifolia, synonyms including 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.

Some molecular studies have suggested that Maxillaria should be split into several genera, with this species moved to Heterotaxis, but as of August 2023, Plants of the World Online treats Heterotaxis as a synonym of Maxillaria.
