Common Name The Duck Foot Epidendrum [refers to the lip]

Flower Size 2.4" [6 cm]

Found in Ceara state of Brazil at elevations around 550 meters as a miniature sized, warm growing epiphyte with simple, cane-like, laterally compressed above, straight to slightly flexuous stems and carrying 3 to 4, all along the stem, spreading, coriaceous, smooth, ovate-elliptic, retuse, basally clasping leaves that blooms in the late summer and early fall on a terminal, on a mature stem, occuring only once, subumbellate, simultaneously 3 flowered inflorescence with much shorter than the ovary, triangular, acute, scarious floral bracts.

"Epidendrum anatipedium is part of GROUP Difforme haracterized by the caespitose, sympodial plants, fleshy, pale green to glaucous leaves, apical inflorescence, sessile, rarely with a short peduncle, one-flowered to many-flowered, and then corymbose, without spathaceous bracts, fleshy, green to yellowish-green rarely white flowers. The species is distinguished by the laterally compressed stems, large flowers, sepals 1.2 to 1.4" [30 to 35 mm] long, obtrapezoid lip, the apical margin 3-lobed, the three lobes triangular, the mid-lobe smaller than the lateral lobes, column long, arching, clinandrium-hood prominent, erose. It is similar to Epidendrum amarajiense V.P. Castro & L.C. Menezes from Pernambuco state is similar in size, but the sepals are somewhat wider, petals recurvate, column is straight, clinandrium hood is short, and the lip is reniform and is .44 x .72" [11 x 18 mm], much wider than long. Epidendrum carvalhoi Toscano also endemic to Brazil, from the State of Espírito Santo, has long, narrow sepals and petals, the sepals 1.48 to 2.2" [37 to 55 mm] long, petals 1.2 to 1.6" [30 to 40 mm long], the lip is obreniform, 3-lobed, mid-lobe short, rounded, apiculate, calli elongate, divergent. Epidendrum oldemanii Christenson which is endemic to the French Guyana and has smaller flowers, elliptic sepals .56 to .64 [14 to 16.5 mm] long, lip bilobed, transversely reniform, margin sinuous, and the calli sub-globose. Epidendrum amapense Hágsater & L.Sánchez is found in northeastern Brazil and the French Guyana, has similarly smaller flowers, sepals .52 to .68" [14 to 17 mm] long, a 3-lobed lip, the lateral lobes semi-ovate, obtuse, slightly erose, the mid-lobe transversely rectangular, emarginated, with a wide mucro in the sinus, clinandrium-hood deeply erose dentate. Epidendrum latilabre Lindl. is widely distributed along the coast of Brazil, has .72 to 1.32" [18 to 33 mm] long sepals, a transverse oblong, 3-lobed lip, up to 4 times as wide as it is long, the lateral lobes sub-quadrate, the mid-lobe transversely rectangular, deep and widely emarginated, forming a pair of lobes, column straight, and the clinandrium-hood deeply lacerate. Epidendrum pseudodifforme Hoehne & Schltr., endemic to the coast of Brazil, has terete stems, a 5 to 8 flowered inflorescence, the flowers simultaneous, smaller, sepals .48 to .52" [12 to 13 mm] long, lip 3-lobed, obscurely 4-lobed, margin crenulate; the mid-lobe with a wide sinus forming 2 lobes."
