LATE THROUGH

Common Name The False E paniculatum Epidendrum [refers to its similarity to E paniculatum]

Flower Size .8" [2 cm]

Found in western Colombia and Ecuador at elevations of 100 to 300 meters as a large sized, hot growing epiphyte with an erect to slightly arching, simple, cane like, laterally compressed stem enveloped basally by non-foliaceous, scarious, tubular sheaths and carrying all along the upper 2/3's of the stem, 12 or more, alternate, articulate, erect-spreading, narrowly elliptic to elliptic, acute, margin entire leaves that blooms in the late fall and winter on more than one, terminal to lateral, erect, racemose to pluriracemose, arching-pendent, peduncle 1.8 to 18.4" [4.6 to 46 cm] long, subterete, thin, totally enveloped by lanceolate, acuminate, amplexicaul, partly imbricate bracts, the terminal, elongate 4 to 20" [10 to 50 cm] long, the laterals, 4 to 8 [10 to 20 cm] long, 9 to 25 flowered inflorescence with much shorter than the ovary, very similar to the bracts of the peduncle, lanceolate, acuminate, amplexicaul-spreading relative to the rachis floral bracts and carrying green flowers with a white lip held towards the apex in a cluster.

"Epidendrum pseudopaniculatum belongs to the GROUP Pseudepidendrum which is characterized by caespitose plants, cane-like stems, acute to acuminate leaves, usually apical inflorescence, the filiform petals and the lip usually 3-lobed with the apical lobe often bifurcate; and the SUBGROUP Turialvae which has a racemose and few-flowered inflorescence on an elongate peduncle, usually producing new racemes over the years and thus pluriracemose and the pollinia “bird-wing” type. The species is recognized by the plants with apical and lateral inflorescences with a raceme of flowers at the end of a long peduncle covered by multiple small bracts, green flowers, the lip white, the disc with 5 parallel purple lines on the keels, reflexed sepals .48" to .5" [12 to 12.5 mm] long. Epidendrum paniculatum Ruiz & Pavón has an apical, paniculate inflorescence with a short peduncle covered by 1 to 3, tubular bracts, flowers similar in color but the lip is marked by irregular reddish spots on the disc. Epidendrum piliferum Rchb.f. has a many-flowered apical, paniculate inflorescence (up to 400 flowers), sepals .5 to .68" [12.5 to 17 mm] long, green, the lip white, with 5 purple lines on the disc, and the ovary ornamented with moniliform trichomes."
