Pleurothallis saccata Ames, Sched. Orch. 4: 25. 1923, syn. nov. TYPE: COSTA RICA. Cascajal, C. H. Lankester K340 (HOLOTYPE: K!)
The lectotype is the only known specimen that was annotated by Kraenzlin as P. colossus. This species is amongst the largest of Pleurothallis, with a range including Costa Rica, Panama, Colombia, and Ecuador (Luer, pers. comm.). Luer and I agree that this is the earliest name for the plants tra- ditionally referred to P. praegrandis Ames in Panama (Dressler, 1980) and P. saccata Ames in Costa Rica (Lankester, 1959).
