Epidendrum rigidum is an epiphytic reed-stemmed Epidendrum orchid common throughout the Neotropical lowlands, below 600 m (2,000 ft). (The Flora of North America recognizes a distinct species, E. cardiophorum Schltr., which replaces E. rigidum in Mexico and Central America; Kew lists E. cardiophorum Schltr. as a synonym for E. rigidum.)
