"Epidendrum rauhii belongs to the GROUP Secundum SUBGROUP Secundum and is recognized by the small plants with the base of the stems thickened and subsphaerical and the small, non-resupinate, white flowers with a large yellow, 7-tuberculate callus on the disc. It is similar in size to Epidendrum gracicaule now = Epidendrum secundum which was described from Peru without locality, which has orange-yellow flowers and the sepals and petals somewhat narrower; the size and base of the stem not known."
