Discussion

Epidendrum nocturnum is widespread and common throughout the tropical regions of the Western Hemisphere. Outside the flora area, the size of stems, leaves, and flowers is somewhat variable, and plants or whole populations often have cleistogamous flowers. A number of good species occur in the Neotropics. The length of the ovary and the pedicel of the capsule often are good specific characters.

Flowers are very fragrant at night, with an almost pungent scent.
