Caucaea sanguinolenta (Lindl.) N.H. Williams & M.W. Chase 2001

Photo by Rudolf Jenny

Common Name The Bleeding Caucaea [refers to the spots on the lip]

Flower Size .9" [2.2 cm]

Found in Venezuela and Colombia as a small sized, cold growing epiphyte occuring at elevations around 3000 meters with pear to egg-shaped pseudobulbs enveloped basally by overlapping triangular sheaths and carrying a single apical, elliptic, acute leaf that is basally longitudinally folded along the midvein for a short distance, making a petiole-like stem that blooms on an axillary, 8" [20 cm] long, 5 to 8 flowered inflorescence holding the wide spread flowers towards the apical third.

CAUTION!! This species and C mimetica are often cited as synomonous with this species taking precedence but if the determinations that I have are correct then there are big differences in the callosity of the lip, so I have left them and their synonyms separate at this time.
