Common Name Dodson's Dressleria [American Botanist in Costa Rica and Ecuador Current]

Flower Size

Found in Ecuador on the eastern slopes of the Andes at elevations of 1000 to 1400 meters as a medium sized, cool growing epiphyte with swollen, oblong, 8 to 10 internoded pseudobulbs carrying 8 to 10, basally clasping, distichous, thin, narrowly oblong-ellipticto oblong-obovate, acuminate leaves that have a persistent foul odor, that blooms in the fall on one to several basal, to 12" [30 cm] long, erect, 5 to 18 flowered inflorescence with simultaneously opening, fragrant flowers.

Very similar to and almost indistinguishable from D fragrans except for the differences in location, minor lip details and mostly fragrance which attract different pollinators. D dodsoniana has a fragrance of Methyl salicylate and only attracts the male bees of the species Eufriesia concava
