Fragrant partial sun Cool LATE Summer EARLY Fall

Common Name Cuevas' Habenaria [Mexican Botanist Current]

Flower Size

Found in Jalisco state of Mexico at elevations around 1400 to 2000 meters as a miniature to small sized, cool growing terrestrial with a pendulous, oblong-ellipsoid, wrinkled tuber giving rise to an erect, slender stem carrying to 8, cauline, in a spiral, almost distichous, arching, spreading to erect, cuneate, elliptic-lanceolate to lanceolate, dark green leaves that blooms in the late summer and early fall on a terminal, erect, semi-cylindrical, lax, .6 to 1.6" [1.5 to 4 cm] long, 2 to 7 flowered, yellow green inflorescence with shorter to longer than the ovary, erect to adpressed, conduplicate, revolute sided below, subcordate-triangular, acuminate floral bracts and carrying, simultaneously opening, fragrant flowers.

"Habenaria cuevasiana is related to H. lactiflora but is characterized by weak plants; an arched nectary that is equal to or slightly larger than the ovary, almost without dilating in the distal part; the anther channels and rostellum arms are arched and somewhat descending; highlight at the base of the glandular stigmatic processes. Habenaria cuevasiana is sympatric with H. socorroae which is why we compare the two species, although they are not closely related. In the second the foliage is opaque, without hyaline nerves; the underextended dorsal sepal with the keel is denticulated and less prominent; The anterior segment of the petals is shorter than posterior lobe; the nectary is more dilated in the distal part; straight anther channels and rostellum arms, with the main body forms a 90° angled sinus, the stigmatic processes are shorter than the blade, with the protrusion at the base devoid of glands. Habenaria clypeata is distinguished by the posterior lobe of the petals wider by half, with two nerves; the apical part of the nectary narrower; the anther channels slightly descending in the part distal; the straight column on the back; Floral bracts more wide at the base, mainly subcorscript. Habenaria cuevasiana coincides in many details with H. lactiflora but differs in some features that are considered to be of importance in the separation of Habenaria species such as floral bracts subcordiform at the base; middle lobe of the labellum of the width at the base is half as wide;lLength of the column, the rostellum broad, rounded, and the glands in the internal front of the shoulder of the processes stigmatic. In H. lactiflora these same attributes floral bract subtruncated at the base; middle lobe of the cuneate labellum, that is wider in front of the half that at the base; column .64" [1.6 mm] long , rostellus very attenuated, triangular, sharply rounded and absence of glands in the basal ridge of stigmatic processes."
