TYPE: MEXICO. Oaxaca: Sierra de San Felipe, 7500 ft, 14 Jun 1894, C. G. Pringle 4728 (HOLOTYPE: NY!; ISOTYPES: AMES!, BR, CM, E, F, G, LE!, M, MEXU, MINN, P!, PR!, S!, UC!, US!, W, Z).

Species haec E. parkinsoniano Hook. similis ab ea foliis 3-5 et labello non profunde lobato differt.

Examination of the holotype of Epidendrum pugioniforme Regel shows that taxon to be conspecific with E. parkinsonianum Hook. (q.v. Hagsater, 1 990a). The narrowly restricted Mexican endemic (from Guerrero and Oaxaca), previously thought to represent E. pugioniforme Regel (q.v. Hagsater, 1990b), appears to be undescribed. I take this opportunity to describe this new species in honor of Eric Hagsater (AMO), whose contributions have transformed our understanding of Mexican orchids and the genus Epidendrum.
