The first photo is what Eric Christenson has found to be exactly like the type specimen, the second is what we all have thought E hartwegi was.
This small to medium sized, hot to cold growing, epiphytic species is found from Venezuela, Colombia, Ecuador, Peru and Bolivia in very wet montane forests on moss covered trees at elevations of 1300 to 3100 meters often in full sun with clustered, compressed, conical to ellipsoid pseudobulbs carrying a single [mostly], linear-elliptic, acute leaf and blooms in the spring on an apical, 5 1/2" [14 cm] long, erect, few to several flowered, racemose inflorescence arising on a newly matured pseudobulb with fleshy, non-resupinate flowers.
Synonyms Encyclia hartwegii[Lindl.] R. Vásquez & Dodson 1982; *Epidendrum hartwegii Lindl. 1844; Prosthechea hartwegii (Lindl.) W. E. Higgins 1997
