Common Name Linden's Peristeria [Belgian Plant collector 1800's]

Flower Size 1 1/4" [3 cm]

This robust, caespitose, large sized, hot to warm growing, epiphytic species comes from Colombia, Peru and Ecuador in montane rain forests and is found at elevations of 800 to 1000 meters with ovoid, tapering upward pseudobulbs subtended by several pairs of short scarious sheaths with 3 apical, plicate, lanceolate-elliptic, acute or acuminate, dark green, narrowing below into the short, conduplicate, channeled, petiolate base leaves that blooms in the winter and spring on a basal, horizontal, short to 1 1/2" [4 cm] long, densely congested, sub-umbellate, racemose inflorescence arising as a new growth emerges with small, concave, ovate-triangular, spotted with dark purple floral bracts and carries fragrant flowers.

The winged column seems to be the distinguishing factor here.
