LATE EARLY

Common Name Ibarra's Habenaria [Mexican Collector of the type species current]

Flower Size .4" [1 cm]

Found in Jalisco state of Mexico in rocky volcanic soils in pine/oak forests at elevations of 2200 to 2500 meters as a small to medium sized, cool growing, inconspicuous terrestrial with oblique, ovoid tuber giving rise to an erect, very thin stem carrying 10 cauline, lowermost reduced to sheaths, above resembling floral bracts, the largest are located in the middle part, ascending; with three nerves raised in carinas decurrent, lanceolate, acuminate lamina, up to .84" [2.1 cm] long, .28" [7 mm] wide, sulcate leaves that blooms in the late summer and early fall on an erect, terminal, 2.08" [5.2 cm] long, in a unilateral cluster, 8 flowered inflorescence with conduplicate, amplectant, ovate-lanceolate, acuminatewith three ribs raised in carinas, the carina and the margins denticulated, the verruculous surface, shorter than the ovary floral bracts and carrying small, green flowers.

"In fresh or dried specimens Habenaria ibarrae can be confused with H. ruizii , with whom he is related. In Habenaria ibarrae the leaf blades are erect, up to .84" [2.1 cm] long,.28" [7 mm] wide; subextended dorsal sepal, ca. .2" [5 mm] long; arching labellum lobes reflexive; the side lobes of the labellum ca. .28"[7 mm] long; the middle lobe ca. of .24" [6 mm] long and the cylindrical spur is slightly longer than the ovary and the middle lobe of the labellum and is very little dilated in the rounded, front half which is .58" [14.5 mm] long. Habenaria ruizii has extended leaf blades, the larger .148 to 2" [3.7 to 5 cm] long, .3 to .64" [7.5 to 16 mm] wide; an erect dorsal sepal, .26" [9 mm] long; lobes of the labellum pendant; .36" [9 mm] long side lobes from the breast; the middle lobe .36" [9 mm] long and the spur is shorter than the ovary and the middle lobe of the labellum is inflated towards the broad apex, which is .28" [7 mm] long. In turn Habenaria flexuosa with which our species is also related has the following traits; the eaf blades are erect or ascending, .88 to 2.4" [2.2 to 6 cm] long, .52 to 1.04" [1.3 to 2.6 cm] long wide; an erect dorsal sepal, .36 to .44" [9 to 11 mm] long; the hanging labellum lobes; side lobes from .36 to .48" [9 to 12 mm] long; the middle lobe .296 to .48" [7.4 to 12 mm] long."
