Common Name Eaton's Habenaria [Alvah Augustus Eaton American Botanist that worked with Oakes Ames in his publications of Habenaria 1865 to 1908]
Flower Size
Found in Jalisco state of Mexico in pine/oak forests among rocks on volcanic soils at elevations of 2300 to 2900 meters as a small to medium sized, cold growing terrestrial with a subspherical tuber giving rise to an erect, smooth, cylindrical stem carrying 7 to 9, cauline, erect or ascending, with the apex retroflex, the first two reduced to sheaths, the next develops a small lamina and then ascending larger, the largest located just above the middle of the plant, subcoriaceous, lanceolate, acuminate, furrowed, almost flat, opaque green, carinated along the central nerve leaves that blooms in later summer on an erect, terminal, rachis somewhat sinuous, about 3.4 to 8.8" [8.5 to 22 cm] long, provided with three carinas, the central one being higher, the raceme not very dense, subcylindrical, simultaneously 9 to 15 flowered inflorescence with triangular-lanceolate, acuminate, furrowed, with three ribs, the reticulum lax, with a prominent carina downwards, exceeding the flowers below, in the distal part of the cluster equaling the ovary, erect, for the most part conduplicated, the lower ones leave the ovary free, the superior conceal it floral bracts.
"Habenaria eatoniana is related to H. filifera but it is distinguished by 10.6 to 12.8" [26.5 to 32 cm] tall plant; the first two leaves reduced to sheaths, almost flat, the largest located a little above half of the plant, lanceolate, acuminate, 1.68 to2.28" [4.2 to 5.7] cm long, .64 to .88" [1.7 to 2.2 cm] wide; the inflorescence has a sparse raceme; the lowest floral bract exceeds the first flowers, equalling the ovary above; an elliptical attenuated, dorsal sepal, .38 to .38" [9.5 to 11.5 mm] long, .18" 4.5 mm] wide; lanceolate lateral sepals .38 to .44" [9.5 to 11 mm] long, .08 to .14" [2 to 3.5 mm] wide; posterior lobe of the petals oblong-triangular, .36 to .4" [9 to 10 mm] long, .68 to .8" [1.7 to 2] mm wide; the anterior lobe more or less equal in length; side lobes of the labellum .44 to .52" [11 to 13 mm] long, .028 to .04" [0.7 to 1 mm] wide; the oblong, acute middle lobe, .44 [11 mm] long, .06 to .072" [1.5 at 1.8 mm] wide and acuminate nectary, .8" [20 mm] long, .04" [1 mm ]wide. In Habenaria filifera the leaves are erect, the cluster is dense and narrow because the flowers are erect and adpressed; the ovary lacks angles in the ribs; the dorsal sepal is suborbicular, .24" [6 mm] long; the posterior lobe of the petals is subauriculate at the base of the posterior side, narrower .028" [0.7 mm] wide; the lateral lobes of the labellum are arched, ascending, .28" [7 mm] long and a .44" [11 mm] long nectary."
