Common Name The Orange Aa
Flower Size .16" [4 mm]
Found in La Libertad department of Peru on grassy, apine slopes at elevations around 3500 to 4000 meters as a small sized, cold growing terrestrial with leaves that are withered at blooming which occurs in the spring on an erect, terminal, to 12" [30 cm] long, provided with up to 23, diaphonous sheathing bracts, rachis .88 to 2" [2.2 to 5 cm] long, sparsely pilose, cylindrical, densely many flowered inflorescence and ovate, acute to obtuse, slightly erose margined, reflexed floral bracts that are slightly longer than the non-resupinate, orange to reddish orange flowers.
"Besides flower color, this Aa species can be distinguished from Aa aurantiaca by its wide opening lip, glabrous sepals and ovary, and acuminate floral bracts which notoriously surpass the flower (50% larger). Aa aurantiaca is similar to Aa rosei, but it can be distinguished by the orange flowers, dorsally hairy sepals, ovate-lanceolate, 3-nerved petals, and narrower opening of the lip." D Trujillo 2011
