ISOZYME NUMBER IN SUBTRIBE ONCIDIINAE (ORCHIDACEAE): AN EVALUATION OF POLYPLOIDY [PDF]

American Journal of Botany, 1988
The Oncidiinae has attracted attention because of the variation it exhibits in chromosome number, n = 5–30, which is greater than the range in the rest of the Orchidaceae. The genus Psygmorchis, with n = 5 and 7, has been a particular focus of controversy, and many authors have suggested that 5 and 7 are the base numbers for the subtribe.
