Common Name or Meaning The Little Pinecone Odontoglossum
Flower Size 1/2" [1.25 cm]
Found in Peru in wet montane forests at elevations of 1600 to 1800 meters as a miniature to small sized, cool growing terrestrial with ellipsoid, complanate pseudobulbs enveloped basally by several foliaceous bracts that are shorter than the 2, oblanceolate, acuminate, narrowing below into the petiolate base leaves that blooms in the late spring on an erect, paniculate, racemose, to 4 3/4" [12 cm] long, several [9 to 10] flowered inflorescence with 2 flowers open at a time holding the flowers at leaf height and has tubular, clasping floral bracts.
This species is cited as a synonym of Cyrtochilum fractum and may be that species but until I get more information and better photos, I will leave them separate.
