" Epidendrum camilae belongs to the GROUP Diothonea which is characterized by the branching plants, linear lanceolate to oblong, bilobed leaves, racemose, arching-nutant inflorescence, membranaceous flowers (rarely fleshy), the entire to 3-lobed, ecallose lip with the margin erose without or with 1 to 10 thin, smooth to erose ribs, the column completely to obliquely united to the lip. The new species has leaves to 3.2" [8 cm] long, sepals dorsally prominently conically to sub-conically uncinate, lip 3-lobed, base narrowly saccate with the column, within the column with a pair of prominent laminar winged ribs attached to the sides, and with a prominent laminar mid-rib at the bottom of the sac, outline like a bell-shaped curve, all this hidden by the column; free portion of lip flat, 3-lobed, ecallose, margin erose, formed by lateral lobes dolabriform, semi-orbicular, mid-lobe transversely reniform, forming two shallow, curved lobules, apex emarginate. Epidendrum astetei Hagsater, Collantes & Mormontoy is very similar but has shorter leaves, to 5.8 cm long, also has prominently uncinate sepals, lip nearly totally united to the column, 3-lobed, basally sac-like; disc with two pairs of blade-like ribs, the inner pair well developed, sigmoid-folded, with the anterior borders visible below the apex of the column as a pair of folded calli, with a prominent hemi-cordate mid-rib hidden in between the inner sides of the inner pair; the basal pair smaller in size, sigmoid, transversely sub-rectangular, sub-retuse. Epidendrum trachypentatropis Hágsater & E.Santiago has small reddish flowers, dorsally muricate sepals .22 to .228" [5.5 to 5.7 mm] long, and the sack-like lip nearly totally united to the column, with 5 prominent, unequal, flat, laminar keels hidden below the column. Epidendrum trachysepalum Hágsater has up to 9 to 11, pale pink to yellowish brown flowers with wine-red veins, the sepals are strongly muricate, the lip totally free from the column and is adorned with 3 thin, ribs at the base of the lip, the lateral pair is “U” shaped, and the mid-rib only appears on the disc, so on the disc it appears to be 5-ribbed."
