Common Name The Look Alike Epidendrum [refers to this species similarity to E firmum]

Flower Size .8" [2 cm]

Found in Panama in rainforests at elevations of 1500 to 2200 meters as a miniature to small sized, cool to cold growing epiphyte with simple, cane-like, terete, slightly flexuous stems and carrying 4 to 10, all along the stem, coriaceous, terete, elliptic, retuse apically leaves that blooms in the later spring and summer on a terminal, occuring only once, sessile, subcorymbose, 2 to 6 flowered inflorescence with much shorter than the ovary, widely ovate, acute floral bracts and carrying simultaneously opening, resupinate, green flowers.

The Drawing featured above by Hamer is labeled Neolehmannia curvicolumna which is considered to be a synonym of E simulacron.

"Epidendrum simulacrum belongs to the GROUP Difforme which is characterized by the caespitose, sympodial plants, fleshy, pale green to glaucous leaves, apical, sessile inflorescence, rarely with a short peduncle, single flowered to corymbose, without spathaceous bracts, fleshy, green to yellowish-green rarely white flowers. The species has narrow, elliptic leaves, small, green flowers, the sepals and petals reflexed, an entire, reniform-cordiform lip with subglobose calli, and a strongly arched column, to 90°, wlth a short, erose clinandrium-hood. It is similar to Epidendrum firmum Rchb.f., but that species has larger flowers, spreading sepals and petals, and a 3-lobed lip, with a subquadrate midlobe, prominent, elongate, dlvergent calli, and the column not as strongly arched, with a prominent fimbriate clinandrium-hood."
