|discussion=<p>Spur length is extraordinarily variable in <i>Habenaria quinqueseta</i> as here delimited. Recognition of <i>H. quinqueseta</i> var. macroceratitis, a long-spurred variety with a more tropical distribution, has been proposed (C. A. Luer 1972), restricting var. quinqueseta to the United States. Spur length varies continuously, and recognition of segregates based on this feature alone is not warranted (D. S. Correll 1950). Recent study, however, has shown <i>Habenaria</i> macroceratitis Wildenow to be distinct (P. M. Brown 2000c). Both <i>H. quinqueseta</i> and H. macroceratitis vary in spur lengths, and this situation has obscured other differences. This information did not appear in time to be accommodated fully in the present treatment.</p><!--
