Flower Size .8" [2 cm]

Found in Costa Rica and western Panama at elevations around 1500 to 1750 meters as a medium sized, cool growing terrestrial with simple, cane-like, terete, thin, straight at the base and somewhat flexuous towards the apex stems carrying 5, towards the apical half of the stem, alternate, articulate, coriaceous, narrowly elliptic-lanceolate, acute leaves that blooms in the fall and winter on a terminal, occuring only once, racemose, distichous, arching, 2" [5 cm] long including the 1" [2.5 cm] long peduncle enveloped completely by 7, narrowly ovate, subacute, conduplicate, imbricating, glumaceous bracts, successively single, to 7 flowered inflorescence with much longer than the ovary, ovate, subacute, conduplicate, glumaceous floral bracts and carrying greenish yellow, green to purple green flowers.

The rhizomatous plant with the roots arising from the basal nodes of the stem, the elliptic-lanceolate leaves are held at the apex of the stem, the very short inflorescence with the peduncle covered by several imbricate, conduplicate bracts, the longer than the ovary, ovate, acute floral bracts and the small flowers with a sub-orbicular-cordate lip distinguish this species from others.

"Epidendrum estrellense belongs to the GROUP Polychlamys SUBGROUP Polychlamys which is characterized by the successive lateral growths, the distichous, apical inflorescence with prominent, conduplicate, acute, glumaceous floral bracts. The species is distinguished by the thin stems, somewhat flexuous towards the apex, with elliptic-lanceolate, acute leaves, a dense inflorescence with 7 imbricating bracts covering the peduncle, successive, small, greenish yellow to green purple flowers the partly spreading sepals .26 to .4" [6.5 to 10 mm] long, and the lip suborbicular-cordate. Epidendrum barbae Rchb. f. has thin, straight, stems, linear-lanceolate, acute leaves, a lax-flowered inflorescence without bracts on the peduncle, and the rachis zigzag, simultaneous flowers with the ovary inflated, forming a prominent vesicle."
