Flower Size 1/2" [1.25 cm]

Found in Peru in wet montane forests at elevations around 1200 meters as a large sized, cool growing epiphyte with a simple, cane-like, flexuous stems carrying along the apical half, subcoriaceous, oblong-lanceolate, minutely bilobed, articulate below into the base leaves that blooms in the earlier fall on a terminal, erect, finely pubescent, paniculate, densely many flowered inflorescence with several arcuate branches, and carrying finely pubescent, simultaneously opening, resupinate flowers.

"Epidendrum pubiflorum C. Schweinf. belongs to the GROUP Amblostoma SUBGROUP Amblostomioides which is characterized by the caespitose habit, the thinly fusiform stems with narrow, apically bilobed, subcoriaceous leaves distributed along the apical half of the stems, an often large, apical, erect, paniculate inflorescence, the flowers greenish-yellow to white, the ovary and the sepals usually dorsally pubescent, ano the lip 3-lobed. The species has the rachis finely pubescent, slightly larger flowers about as heavy looking, but the petals are .08" [2 mm] wide and the lip is bicallose and 3-keeled, the lateral lobes dolabriform and the midlobe cuneate, truncate. Epidendrum ancirotrotylosum has short, thickened stems, an erect, relatively large, paniculate inflorescence, the rachis glabrous, heavy flowers, the ovaries pubescent, the sepals dorsally sparsely short-pubescent, petals linear, falcate, and the lip deeply 3-lobed, the lateral lobes obliquely oblong-reniform, the midlobe narrowly subrhombic, obtuse, bicallose, the calli with a cuniculus beneath them, and a semicircular, anchor-shaped structure in front. Epidendrum lanipes Lindl. has larger plants and flowers strongly fragrant of citrus, the rachis as well as the ovaries are pubescent, lateral lobes of the lip semiovate, midlobe cuneate, retuse, bicallose with three short keels in front."
