Epidendrum lacustre
''Epidendrum lacustre'' (the "lake ''Epidendrum'') is a sympodial orchid which is known to grow both epiphytically and lithophytically in the cloud forests and rainforests of Colombia, Costa Rica, Ecuador, Nicaragua, Peru and Venezuela at altitudes ranging from 1.2—2.5 km.〔I. F. La Croix ''The new encyclopedia of orchids: 1500 species in cultivation'' p. 188. Timber Press, Portland, Oregon.〕 The type of this species was found growing "on half-submerged rotten trees" in a Venezuelan marsh at an altitude of 2.4 km.〔H. G. Reichenbach "ORCHIDES", nr. 202 in C. Müller, Ed. ''Walpers. Annales Botanices Systematicae'' 6(1861)368. Berlin.〕
== Description ==
''E. lacustre'' was placed in the subgenus ''E.'' subg. ''Spathium'' by Reichenbach; as is typical of plants in this subgenus, ''E. lacustre'' stems are unswollen and covered by sheathes which bear distichous leaves on the upper part of the stem, and end in one or more apical spathes, through which the inflorescence erupts. ''E. lacustre'' stems grow to 1.2 m tall.〔Schweinfurth "Orchids of Peru Supplement", ''Fieldiana: Botany'' 33(1970)38 〕 The leaves are broad and obtuse, to 21 cm long by 7 cm wide. The .3—.4 m long peduncle grows from a double, scimitar-shaped spathe, and bears the large (to 8 cm across) flowers near the end in an almost umbellate raceme. The 12 cm pedicel is four times the length of the ovary. The widely open green sepals and petals are linear with pointed tips. The white lip is adnate to the column to its apex, nearly cordate where it diverges from the column, either barely divided into three lobes or undivided, and pointed at the distal end. The callus consists of two pointed lumps just beyond the column, separated by a 4 cm long raised keel.
