Part sun Warm to Cool Fall Winter

Common Name The Orange Epidendrum

Flower Size 3/4" [2 cm]

Found in Ecuador, Peru, Brazil and Bolivia in wet montane forests at elevations of 450 to 1600 meters as a small sized, warm to cool growing epiphyte on tree trunks with slender, erect stems that are leafy towards the apex and basally enveloped by tubular, scarious leaf sheaths and carrying ascending, narrowly lanceolate, basally clasping, acuminate, thin leaves and blooms in the fall and winter on a densely flowered, terminal, racemose inflorescence arising on mature canes with numerous small flowers.

"Epidendrum armeniacum Lindl. belongs to the GROUP Alpicolum SUBGROUP Alpicolum haracterized by the simple, cane-like stems, long, narrow 1 to 3 spathaceous bracts, fox-tail-like inflorescence and numerous flowers with fleshy lip. The species has similar-sized flowers to Epidendrum boscoense, but the lip is 3-lobed and the habit much larger, and the inflorescence is a densely flowered fox-tail. Epidendrum boscoense at first sight looks like an oversize E. miserrimum Rchb. f., with the parallel-sided spathe and fox-tail inflorescence, though well spaced and laxly flowered. It is recognized by the long, narrow leaves (2 mm wide), the sepals 3.3 mm long and the entire, trowel-shaped lip. Epidendrum dialyrhombicum Hágsater & Dodson also has narrow leaves, but these are some .16" [4 mm] wide, and the inflorescence is compact, many-flowered and the lip free from the column."
