"Epidendrum vesicinanum belongs to the GROUP Nanum SUBGROUP Nanoecallosum , which is characterized by the Dichaea like pendulous stems, the inflorescence produced by pairs of opposite flowers, without spathaceous bracts, but with prominent floral bracts. The new species is recognized by the green flowers, inflated nectary at the apical half of the pedicellate ovary, and the small column. Epidendrum integrinanum Hágsater has large, caespitose plants (about ca. 2.4 to 12" [6 to 30 cm] long, widely lanceolate leaves, with cream-greenish tone flowers, resupinate, with dorsal sepal oblanceolate, and lateral sepals oblanceolate-elliptic .372 to .384" x .1 to .104' [9.3 to 9.6 x 2.5 to 2.6 mm] and by the small sub-entire lip, .16 x .1" [4.0 x 2.5 mm], the mid-lobe triangular, longer than wide and the the lateral lobes very reduced, hemi-orbicular and rounded. Epidendrum bonitense Hágsater & Dodson has long plants 4 to 12" [10 to 30 cm], stems horizontal to hanging, all covered with ancipitose sheaths, flowers glaucous green with a faint purple tinge, a long ovary .48" [12 mm], long sepals and petals .48 and .4" [12 mm and 10 mm], respectively, a trilobate lip .2" [5 mm] long, with mid-lobe subrectangular. Epidendrum leuconanum Hágsater & L.Valenz., is found in the same general area of Oxapampa, but in low montane forest on white sand and has apical and axillary inflorescences, with pale greenish white flowers and the pedicellate ovary thin, not inflated, with a 3- lobed lip, lateral lobes .044 x .052" [1.1 x 1.3 mm] and the mid-lob .08 x .06" [2.0 x 1.5 mm] long. Epidendrum tingo-mariae Hágsater has an arched column with a prominent, erose clinandrium, green flowers, with the anther also green, and the short nectary that does not penetrate further than the perianth and thus ovary thin throughout."
