Found from southern Mexico south to Nicaragua as well as Cuba and Jammaica in lower montane rainforests at elevations of 600 to 2600 meters as a miniature sized, warm to cold growing epiphyte, lithophyte or terrestrial with rigid, simple, cane-like, terete, thin but robust stems enveloped by warty, leafless sheaths below and carrying 13 to 30+ on the apical half, distichous, articulate, erect-spreading, lanceolate to linear-lanceolate, acuminate apically leaves that blooms in the late spring through fall on a terminal, without a spathe, occuring only once, peduncle terete, delgado to robust, straight, .8 to 2" [2 to 5 cm} long, paniculate, rarely racemose, erect, 4 to 16" {10 to 40 cm] long, slightly flexuous rachis, simultaneously 20 to 500 flowered inflorescence with lanceolate, acuminate, gradually shorter floral bracts and carrying resupinate flowers that are without fragrance except in Jamaica where they are scented.

"Epidendrum verrucosum belongs to the GROUP Oerstedella which is characterized by the sympodial habit, mostly verrucose stems, and the rostellum which is perpendicular to the axis of the column instead of parallel forming a wide, open sinus and without a viscidium, and the SUBGROUP Verrucosum recognized by the small to medium sized, membranaceous flowers with sepals and petals immaculate, a bilobed clinandrium-hood slightly surpassing the body of the column, obovoid, subequal pollinia with long granulose caudicles. The species is recognized by the tall plants to 10' [up to 3 m] long, paniculate inflorescence with numerous white flowers, the callus yellow, or sepals and petals white or greenish cream and the lip creamy-yellow, the lobes of the lip similar, rectangular-oblong, inserted at about 45°. It is similar to E. myrianthum Lindl. Which has somewhat smaller plants to 6' [1.8 m], similar but lilac-colored flowers. Epidendrum macdougallii (Hágsater) Hágsater has short, thin-stemmed plants to 3' [90 cm] tall) with a generally racemose inflorescence, the peduncle with several bracts, and lilac pink flowers."
