Flower Size
Found in Jalisco state of Mexico in clay soils, in tropical deciduous forest remnants or secondary holm oak forests and mixed pine and oak forests, roadsides, among grasses, in full sun or under the shade of the trees at elevations of 1400 to 1660 meters as a medium to large sized, cool growing terrestrial with vertical, potato-like, ellipsoid tubers giving rise to an erect, uncovered in small stretches below the sheaths, robust, smooth stem carrying cauline, rigid, erect or arching, straight, with the apex barely arched, of ash-green color, basally reduced to imbricate sheaths, above with a blade and some space between, above the middle of the plant they decrease and the sheath is shortened, the latter are similar to the floral bracts; in the obtuse basal leaves and in the acuminate apical leaves, shallowly concave sheath below in the middle part suborbicular, elliptical to ovate-lanceolate or lanceolate, with a minuscule apiculus, up to 3.8" [9.5 cm] long, 2.32" [5.8 cm] wide, with several thin ribs, the central one raised in a fine carina leaves that blooms in the summer on an erect, terminal, cylindrical rachis, not very angular, pale green, held in a loose cluster, 5.6 to 11" [16 at 27.5 cm] long, 3.3" [8 cm] in diameter, simultaneously 14 flowered inflorescence with erect, shallow concave, ovate-lanceolate, acute, with nine ribs, shorter than the ovary floral bracts
"Habenaria teresae is related to H. macroceratitis with which it shares the nectary three times longer than the ovary, but in H. teresae the basal leaves are obtuse in the acuminate apical leaves, in the middle suborbicular part, up to 3.8" [9.5 cm] long; the floral bract with nine nerves, the carina fine; the narrower side lobes of the labellum, the apical part arched upwards and forwards, by no means rolled, linear, obtuse, 1.12" [28 mm] long, with three ribs; deltoid, obtuse rounded rostellum, the arms .06" [1.5 mm] long from the stylidium, both collateral arms, by no means convergent and with oblong-obovate polliniums. In H. macroceratitis the leaves are acute to subobtuse, 4.8 to 5.8" [12 to 14.5 cm] long, emerald green with silver stripes; the floral bracts with five nerves not very elevated in carinas; the side lobes of the antrorse labellum with the distal part incurved, filiform, attenuated from the base, acuminate, 1.24 to 1.84" [31 at 46 mm] long, with two ribs; triangular rostellum, orthogonal; the anther channels and rostellum arms are arched, collateral to poorly converged and they exceed the stelidia in lateral view and the pollinia is oblong-elliptical."
