Common Name The Twice Grooved Epidendrum [a misnomer has only one]

Flower Size 1.2" [3 cm]

Found in Costa Rica and Panama at elevations of 1500 to 2500 meters as a medium sized, cool to cold growing epiphyte with simple, cane-like, terete, thin, straight stems carrying 2 to 4, towards the apex, alternate, subcoriaceous, oblong, entire margin, acute, conduplicate into the base leaves that blooms in the fall through winter on a terminal, occuring only once, racemose, arching, thin, ancipitose inflorescence with a bract towards the middle that is similar to the shorter than the ovary, triangular, acuminte floral bracts and carrying 6 to 9 successively opening, non-resupinate, nocturnally fragrant flowers with olive green tepals and a lighter lip with a purple cast over it.

CAUTION The drawing is the type so it must be correct but the two flower photos are quite different and I cannot be sure of which is correct if not both or neither. The First photo is the same as the drawing in every respect other than the single flower with a long pedicel and the lip apex which appears to be bilobed, and the second photo which is correct in how the flowers are held but the photo just is not good enough to inspect the lip.

This species is known for having 2 apical, leaves on the stem, green flowers with a slight tint of bronze on the sub-orbiuclar lip that is slightly emarginate and bisulcate in front of the calli
