Flower Size

Found in Jalisco state of Mexico in disturbed holm oak forest, at elevations around 1700 meters as a small sized, cool growing, slender terrestrial with a vertical, pubescent, spherical tuber giving rise to an erect, thin, clear green, ribbed, leafy throughout stem carrying 7 to 8, slender, rectilinear, sheathing, the first two reduced to pods, increasing as they ascend, the last few short and narrow, the largest located in the middle of the the plant, lanceolate or elliptical-lanceolate, acuminate, green, with three to five main nerves raised in carinas; hyaline edged leaves that blooms in the late summer on a terminal, erect, very lax, cylindrical, rachis somewhat fractiflex, 1.56 to 1.8" [3.9 to 4.5 cm] long, five to nine flowered inflorescence conduplicate, concave shallow, lanceolate, acuminate, with a carina, dense reticulum, hyaline edges, with the first flowers equaling to exceeding the ovary, in the latter is shorter floral bracts.

"Habenaria aguirrei is related to H. filifera but the first two leaves are reduced to sheaths, the largest located in the middle of the plant, lanceolate or elliptical-lanceolate, from 1.4 to 1.52" [3.5 to 3.8 cm] long, .44 to .48" [1.1 to 1.2 cm] wide; dorsal sepal ovate-lanceolate, subobtuse, .2" [5 mm] long, .12" [3 mm] wide; triangular-lanceolate acuminate, lateral sepals, .2" [5 mm] long, .08" [2 mm] wide; an acute posterior lobe og the petal, .2" [5 mm] long, .04" [1 mm] wide; the anterior lobe .26" [6.5 mm] long, .024" [.6 mm] wide; the lateral lobes of labellum cintiform and sharply rounded, .36" [9 mm] long; middle lobe .32" [8 mm] long; nectary shorter than the ovary and as long as the middle lobe of the .32" [8 mm] long labellum. Habenaria aguirrei is found on the same face of the hill of the town of Tequila as H. tequilana is found, but this one is distinguished by 8 to 10 leaves, the first three or four reduced to sheaths or with a very short blade, then almost all of the same shape and size, the the latter much narrower, similar to the lanceolate, acuminate floral bracts; the largest located in the middle of the inflorescence or a little above; the inflorescence with seven to fourteen flowers; the dorsal sepal elliptic, subobtuse, with a tiny mucron; the lateral sepals oblique, obovate-spatulate; the posterior petal lobe oblong, attenuated at the distal end, acute; the anterior lobe from .3 to .32" [7.5 to 8mm]."
