"Habenaria variegata is distantly related to H. jaliscana but H. variega it is differentiated by the ovary from .6 to .84" [15 to 21 mm] long, .06 to .08" [1.5 to 2 mm] in diameter, ribs round; dorsal sepal .28" [7 mm] long; ovate-lanceolate lateral sepals, .3 to .32" [7.5 to 8 mm] long, .16" [4 mm] wide; the posterior lobe of the petals oblong, obtuse, .24 to .26" [6 to 6.5 mm] long; the anterior lobe tapered, obtuse-rounded, .28 to .3" [7 to 7.5 mm] long; the subsessile labellum with rounded side lobes, .34" [8.5 mm] long, .028" [0.7 mm] wide; the middle lobe oblong, obtuse, .3 to .32" [7.5 to 8 mm] long; the retrorse, acinaciform, acute-rounded nectary, .64" [16 mm] long; the trapeziform rostellum, shorter than the middle of the spine and the underextended stigmatic processes, contracted in the distal end. Habenaria jaliscana has an ovary of 1.2 to 1.6" [30 to 40 mm] long, .16 to .24"[4 to 6 mm] wide, winged along the nerves and also in the portion between them; dorsal sepal .34 to .4" [8.5 to 10 mm] long; the lateral sepals ovate, subacute, .4 to .56" [10 to 14 mm] long, .022 to .028" [5.5 to 7 mm] wide, the margins at the apical end sawed; the posterior segment of the petals are falcate, acute, .32 to .36" [8 to 9 mm] long; the anterior lobe almost threadlike, attenuated, acuminate, .64 to .96" [16 to 24 mm] long; unguiculated labellum; acuminate lateral lobes, .92" 23 mm] long, .048" [1.2 mm] wide; median lobe, acute, sigmoid nectary, slightly dilated in the distal part, rounded, a triangular, subacute rostellus, about two-thirds of the length of the column and extended stigmatic processes, longer than the spine, contracted towards the base."
