Epidendrum nocturnum

Epidendrum nocturnum (the "nocturnal epidendrum") is the type species of the genus "Epidendrum" of the Orchidaceae (Orchid family).
The species occurs in Florida, Bahamas, West Indies, Belize, Central America to northern Brazil and the Guyanas. "Epidendrum nocturnum" is common in South Florida.
It is usually autogamous (flowers self-pollinate) and sometimes cleistogamous (flowers self-pollinate before they open).
The haploid chromosome number of "E. nocturnum" has been determined as "n" = 20. The diploid chromosome number has been determined both as 2"n" = 40 and as 2"n" = 80.
In 1984, the variety "E. nocturnum" var. "guadeloupense" was determined to have a diploid chromosome number of 2"n" = 42—48. On November 7, 2010, Kew did not recognize the existence of this variety in its World Checklist of Selected Plant Families.
