Common Name McVaugh's Habenaria [American Botanist in Jalisco Mexico 1900's]
Flower Size
Found in Jalisco, Michoacan, Oaxaca and Mexico states of Mexico in pine/oak forests at elevations around 2270 meters as a medium sized, cold growing terrestrial with 7 to 9, cauline, bottomost 3 reduced to cucullate bracts, gradually larger above, the largest near the middle of the stem, decreasing above the middle into the floral bracts, ascending, flat, elliptic-lanceolate to ovate-lanceolate, acute to acuminate, 3 nerved, middle nerve carinate leaves that blooms in the late summ er and early fall on a terminal, erect, [9 to 18 cm] long, cylindrical, 11 to 26 flowered inflorescence with ascending, conduplicate, lanceoalte, acuminate, longer than the dorsal sepal below, shorter than the ovary above floral bracts.
"Habenaria macvaughiana is similar to H. diffusa , but it differs in its longer ovary .84 to .92" vs .56" [21 to 23 mm vs. ca. 14 mm), sepals obliquely ovate (vs. obliquely lanceolate), posterior lobe ofthe petals obliquely deltoid (vs. falcate), broader .04 to .068" vs .04" (1 to 1.7 vs. 1 mm wide) and rounded (vs. acuminate) mid lobe of the lip, and in its more or less cylindrical nectary that is more than twice as long as the midlobe of the lip (vs. clavate-fusiform and slightly longer than the midlobe of the lip). In the original description, H. macvaughiana was compared to H. crassicornis ; however, it is different in their petals and lip, which are pubescent with narrower lobes, and the nectary is shorter than the midlobe of the lip."
