Epidendrum excisum is a species of orchid known to grow both epiphytically and terrestrially on steep rocky banks in mountainous regions of Colombia, Ecuador, Peru, and Venezuela.

The flattened stems grow to 0.9 m tall[1] and are covered by the basal sheathes of the broad, oblong, leathery leaves.

[2] The long base of the paniculate inflorescence erupts from two short, broad spathes at the apex of the stem.

The central lobe is divided into three short rounded lobes at its end: the central one narrow and bent downward, the lateral ones slightly longer, pointing outward and bent upward.

grandiflorum was recognized in Reichenbach, 1861, with generally larger flowers, and occasionally, with "great horizontal cucullate spathes."
