Located in the eastern mountain range of the central Peruvian Andes, within a humid forest dominated by Polylepis canoi and Polylepis argentea T. Boza & H. R. Quispe (2019: 327). The environment is a typical high elevation Andean ecosystem surrounded by a matrix of grassland, lagoons and occasional snow, with the presence of other genera such as Gynoxys Cass.

5704190CFF957D63FF0CFA13FBCD3471.taxon	etymology	Etymology: — The epithet name refers to the department of Junín, located in the central region of Peru, where the species has been collected. Notes: — Comparisons were made with the species of the subgroup that grow in Junín, as well as closely related species comparing with the type material of E. fruticulus Schltr. (1921: 84), E. physopus Kraenzl. (1905: 87), E. monteagudoi Hágsater & E. Santiago (2013: t. 1459), E. jose-alvarezii Hágsater, Gut. Peralta & Nauray (2015: t. 1531) and E. soratae Rchb. f. (1878 b: 24) (images of type and live material at MO and USM, as well as descriptions); these species being most similar to the new species. Epidendrum fruticulus has yellow flowers, the lateral sepals red-brown, and the lip deeply 3 - lobed. Epidendrum physopus has green to yellow-green flowers, the lip deeply 3 - lobed. Epidendrum monteagudoi has cream colored flowers, sometimes with vinaceous spots, and the lip is shallowly 3 - lobed, the mid-lobe small, widely triangular, obtuse. Epidendrum jose-alvarezii has carmine-red flowers, the lip transversely reniform, with lateral lobes dolabriform-orbicular, with the mid-lobe incipient, emarginate. Epidendrum soratae is the most similar species and is discussed in the diagnosis. Conservation Status: — DD. Data deficient.

5704190CFF8E7D7DFF0CFCE7FCC833F4.taxon	distribution	Distribution: — Peru, Colombia and Bolivia. In Peru it is found in the departments of Apurimac, Cusco, Huancavelica and Junín. It is the most widely distributed species within the whole subgroup, however, its altitudinal range is very restricted, and it can be considered a high Andean species. Records for Peru are found mainly in the central and southern region of the Andes Mountain range. It inhabits wet montane forests. Notes: — Epidendrum soratae was the first species of the subgroup described, together with E. scopulorum, and is recognized by the small plants, the branching stems, the leaves lanceolate, sub-acute, very short inflorescences, the sepals 6.8 – 7 mm, and the lip reniform and slightly 3 - lobed, with the mid-lobe short and slightly bilobed. Due to the vegetative architecture many species have been confused with E. soratae. Today we know that the floral analysis of the species of this subgroup is essential to determine the correct identification. Epidendrum scopulorum was collected in a locality and similar elevation as E. soratae, but that species has sepals 9 mm long and the lip is cordiform with the apex obtuse. Conservation Status: — DD.
