Common Name or Meaning The Dwyer-Like Epidendrum [refers to its similarity to E dwyeri]

Flower Size .8" [2 cm]

Found in Panama in cloud forests at elevations around 2200 meters as a medium sized, cold growing epiphyte with simple, cane-like, thin, basally terete, laterally compressed above, producing new stems from the lower part of the previous stem carrying 6, along the apical 1/2 of the stem, articulate, alternate, narrowly elliptic, acute, minutely apiculate leaves that blooms in the late winter and early spring on a terminal, on a mature stem, occuring only once, paniculate, shortly 3 branched, 4.8" [12 cm] long including the 2.2" [5.5 cm] long, laterally compressed, ancipitose, straight peduncle with a single bract, lax, simultaneously to 20 flowered inflorescence with shorter than the ovary, triangular, acute, conduplicate, amplexicaul floral bracts and carrying non-resupinate, greenish yellow flowers.

"Epidendrum dwyerioides belongs to the GROUP Neowilliamsia characterized by the ancipitose stems and rachis, the rachis with conduplicate, acute bracts, distichous, non-resupinate flowers, the lip often digitate and the 2 or 4 pollinla with 2 hard, laminar, caudicles. The species is recognized by the paniculate inflorescence with greenish yellow flowers with brown spots, a very reduced subentire, white lip with a pair of trangular lateral lobes, the nectary wide in front of the stigmatic cavity and narrow at the bottom. Epidendrum dwyeri Hágsater has a similar inflorescence but the flowers are larger sepals .28 to .344" [7 to 8.6 mm] long, the lip subentire with the margin trullate to forming 4, short, digit-like lobes. Epidendrum philowercklei Hágsater & Santiago has the lip clearly 3-lobed, with the column and claw of the lip forming a wide aperture and the nectary wide and rounded at the bottom."
