• Synonyms:
• Selenipedium caudatum var. roseum Du Buysson in L'Orchidophile, Traite Theorique et Pratique sur la Culture des Orchidees, p. 470 (1878) - may be a synonym of Phrag. wallisii rather than Phrag. caudatum var. warszewiczii; more investigation needed

Habitat Data

• Distribution:
  
• Elevation: 1000-2100 m
• Peak Flowering in the Wild: June-July
• Ecology: commonly found in cool, wet forests, also on steep road cuts, "In Chiriqui, Panama, one population consisted mostly of epiphytes in dead trees and on stumps, while a population only three kilometers away was totally terrestrial." (McCook 1989)
• Mean Temperature Range: 19-20°C
• Light: moderate shade
• Medium: ?
• Water: constant moisture

Notes:

• This taxon has presented the biggest nomenclatural problem within the group of long-petalled phrags.  A discussion on a separate page will hopefully be posted soon.
• "In Chiriqui, Panama, a syrphid fly of the genus Metasyrphus (Grimaldi, per. com.) was collected exiting a basal labellum opening with an intact pollinium on its abdomen." (McCook 1989)
