Found in Costa Rica in wet forests at elevations around 650 to 800 meters as a miniature sized, warm growing epiphyte with simple, reed-like, terete, slightly flexuous stems carrying 5 to 8, linear to lanceolate, basally conduplicate, acute, slightly recurved leaves that blooms in the late spring on a terminal, arising on a mature cane, sessile, single flowered inflorescence with a much shorter than the ovary, triangular, acute floral bracts.

"Epidendrum atwoodii is part of GROUP Difforme c 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. This species can be recognized by the linear to lanceolate leaves, successively single, greenish-white flower, ovary dilated, lanceolate sepals, linear petals, adnate to the basal third of the column, 3-lobed, flabellate lip, fimbriate, prominent c1inandrium. It is similar to Epidendrum mantis-religiosae which has narrowlly ovate sepals, narrowly ligulate petals adnate to the basal of the column, ovate lip, erose, short c1inandrium." Hagsarter etal 1999
