In the Yotoco Forest Reserve, in the Municipality of Yotoco, Department of Valle del Cauca, Colombia (3°50'N, 76° 20'W, 1200 - 1700 m.a.s.n.), a remnant sub-Andean forest of approximately 500 ha, orchids were collected during three years. Eighty species distributed in 46 genera were found. The most species-rich genera are Epidendrum L. (tirthteen species) and Maxillaria Ruiz & Pav. (six species). Macroclinium oberonia (Schltr.) Dodson and Porroglossum muscosum (Rchb. f.) Schltr. were restricted to certain zones, Epidendrum porpax Rchb. f., Campylocentrum micranthum (Lindl.) Rolfe, and Oncidium adelaidae Königer were abundant and widely distributed, and Cryptocentrum latifolium Schltr. and Specklinia picta (Lindl.) Pridgeon & M.W. Chase. were scarce.
