Common Name Hamer's Epidendrum [German Orchid Specialist in El Salvador later 1900's]

Flower Size .8" [2 cm]

Found in Nicaragua and Costa Rica at elevations of 950 to 1150 meters as a small sized, warm to cool growing epiphyte with a simple, reed-like, laterally compressed, straight stem carrying 4 to 9, all along the stem, the lower ones elliptic and spaced apart, the upper ones ovate and imbricating, both bilobed apically leaves that blooms in the fall on a terminal, sessile, occuring only once, 1 to 2 flowered inflorescence with shorter than the ovary floral bracts and carrying resupinate, simulataneously opening, resupinate, very pale yellow green, transluscent flowers.

Known for its imbricate superior leaves, an inflorescence with 1 to 4 small flowers with linear-spathulate petals, a trilobed lip with the lateral lobes dolabriform, crenate and the median lobe is short and emarginate and forms 2 round lobules.

"Epidendrum hameri is a member of the GROUP Difforme characterized 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 similar to E. firmum Rchb. f., but can be recognized by the imbricating upper leaves, 1 to 2 small flowers, and 3-lobed lip with dolabriform, crenate lateral lobes and short, emarginate midlobe forming two rounded lobules. Epidendrum lagenocolumna Hágsater, another similar species, has non imbricating upper leaves, 4 to 6, large flowers, semiorbicular lateral lobes, subquadrangular midlobe, and column swollen at the base because of the nectary unusually broad but constricted and decurved aboye the middle."
