"Epidendrum propinquum is part of GROUP Conopseum SUBGROUP Propinquum characterized by a sympodial, bush-like habit with thin stems carrying subcoriaceous leaves and blooms on a racemose, few flowered inflorescence with mostly yellow to pale green flowers sometimes marked with purple. The species is recognized by the bush-like habit, with roots only at the base of the plant, the relatively wide, .56 to .76" [14 to 19 mm], grassy leaves, the ovary does not form any vesicle near the perianth, the racemes originate from the apex of leafy stems, the triangular, and acuminate bracts, Epidendrum ledifolium A Rich, & Galeotti has leathery, thicker leaves, .16 to .28 [4 to 7 mm] wide, acute sepals and the bracts are linear-oblong, not acuminate, the apex of the column and the anther are usually red or purple, Epidendrum lignosum La Llave & Lex, (Kew considers this one a synonym of E lignosum), though similar to E, ledifolium produces the racemes from leafless shoots. Epidendrum skutchii Ames, FT,Hubb. & C.Schweinf. has very long, narrow leaves up to 7.2" x .28" [18 x 0.7 cm], and the lip has radiating keels on the disc in addition to the calli and the central keel,
