Epidendrum adenoglossum
 Epidendrum adenoglossum is an orchid known primarily from its type herbarium specimen Mathews 1073 collected in Peru near Pangoa. When Lindley published the name he placed the species in the subgenus E. subg. Spathium Lindl. (1841). In 2005 Hágsater & Soto designated this species as the lectotype of E. subg. Spathium Lindl.
