Common Name Dickinson's Encyclia [American Orchid Enthusiast and Collector in Mexico 20th cen]

Flower Size 1 1/5" [3 cm]

Found in Mexico, Guatemala, El Salvador, Honduras and Nicaragua in lower montane forests at elevations around 330 meters as a small to medium sized, hot growing epiphyte that is often confused with or cited as a synonym of Enc. guatemalensis but has clustered, conical to ovoid pseudobulbs partially enveloped basally by a few scarious, soon evanescent sheaths and carry 2 to 3 strap-shaped, obtuse, basally graduating into the clasping base leaves as well as having the lateral lobes of the lip distincly different. This species blooms in the spring and summer on a terminal, 2' [60 cm] long, panicle arising on a mature pseudobulb with a few to many glistening, sourly fragrant flowers unlike other Encyclia which are sweeter.

This species is a part of the Encyclia oncidioides complex and most likely is a synonym of it along with, Enc gravida, Enc mooreana, Enc stellata, and Enc guianensis and Enc guatemalensis.

Most likely this species is a synonym of Encyclia guatemalensis but I keep them separate pending more references.
