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 2n = 40 and as 2n = 80.[1]

In 1984, the variety E. nocturnum var. guadeloupense was determined to have a diploid chromosome number of 2n = 42—48. On November 7, 2010, Kew did not recognize the existence of this variety in its World Checklist of Selected Plant Families.
