Common Name Nora's Habenaria [Nora Angélica Esponda Mexican Orchid Enthusiast current]

Flower Size .64" [1.6 cm]

Found in Jalisco, state of Mexico in holm oak groves, in soil rich in organic matter at elevations around 2300 meters as a a small to medium sized, cold growing terrestrial with an ellipsoid to obovoid, finely wrinkled tuber giving rise to an erect, leafy throughout stem carrying 5 to 12, cauline, almost distichous, the first imbricate, reduced to sheaths, then well-developed, extended, ascending, erect or adpressed, more or less arched or rectilinear, the largest located above the middle of the plant, the latter adpressed and similar to the floral bracts; blade rounded or cuneate, elliptical to lanceolate, acuminate, .68 to 1.72" [1.7 to 4.3 cm] long, .28 to .76" [0.7 to 1.9 cm] wide, ashy green on the underside, light green above, opaque, in essence trinerved, furrowed, the reticulum dense, the central nerve raised in carina leaves that blooms in the late summer on an erect, terminal, rachis angular, in a cylindrical cluster, lax, 1.6 to 4.2" [4 to 10.5 cm] long, 7 to 14 flowered inflorescence with conduplicate, somewhat crooked, with the apex incurved, lanceolate to ovadolanceolate or triangularovate, acuminate, light green, fleshy, the keel hyaline, glandular, it exceeds the ovary, the latter a little shorter floral bracts.

"Habenaria norae seems to be related to H. macvaughiana , but differs in the plant that is 8.6 to 13.6" [21.5 to 34 cm] tall; leaves rounded or cuneate, elliptical to lanceolate, acuminate, .68 to 1.72" [1.7 to 4.3 cm] long, .28 to .76" [0.7 to 1.9 cm] long wide; labellum side lobes 5.5 to 8 mm long, slightly shorter or longer than the central lobe which is obtuse; obtuse rounded nectary and the stigmatic processes are oblong-subpentagonal. H. macvaughiana has the plant from 13.4 to 18" [33.5 to 45 cm] high; elliptical-lanceolate ovate-lanceolate, acute or acuminate leaves from 1.8 to 2.24" [4.5 to 5.6 cm] long, .76" [1.9 cm] wide; the side lobes of the labellum are .04 to .042" [10 to 10.5 mm] long, longer than the acute central lobe; the nectary is acute and a little narrower and the stigmatic processes are subsquare. In herbarium specimens Habenaria norae may be confused with H. casillasii , which differs in the following attributes: the anterior segment of the petals is twice as long as the posterior lobe, which is sigmoid in the distal part; the lateral lobes of the labellum are slightly larger than the midlobe; the nectary is shorter than the ovary, the distal part fusiform, thinner comparatively; the column is wider than long; a wider rostellum above, rounded; the arms of the rostellus and the channels of the anther are at an angle greater than 90° to the loculus stigmatic processes without attenuating to the outer side of the distal part, caudicles 1.5 times longer than polliniums, the pollen grains are smaller. Habenaria contrerasiiis located in the same region but differs in the rectilinear, ovate to ovate-lanceolate, acute, leaves, 2.2" [5.5 cm] long, .84" [2.1 cm] wide; the floral bracts in the first flowers well exceeds them, above they exceed the ovary, covers the ovary and the spur, the dorsal sepal is ovate, attenuated and contracted at an obtuse apex, .28" [7 mm] long, .16" [4 mm] wide; the lateral sepals are narrow, lanceolateand acuminate, .28" [7 mm] long and .08" [2 mm] wide; subsquare labellum blade, .04" [1 mm] long, .048" [1.2 mm] wide; the side lobes of the labellum are .4" [10 mm] long, .02" [0.5 mm] wide, longer than the middle lobe; arcuate, acuminate nectary, .056" [14 mm] long, .048" [1.2 mm] wide, the proximal part slender, cylindrical, distally dilated and fusiform."
