Common Name or Meaning The Truncate Cyclopogon [refers to the truncate lip]
Flower Size .25" [6.25 mm]
Found in La Paz department of Bolivia and Brazil in wet montane forests on steep embankments at elevations of 1400 to 2000 meters as a small sized, cool growing, terrestrial to low level trunk epiphytic orchid with 5, basal, rosulate, dark green, spotted lighter green, oblanceolate to round, undulate margins, abruptly narrowing below into the reddish, channeled, petiolate base leaves that blooms in the spring on a terminal, erect, stiff, fleshy, spicate, brown, peduncle to 6.4" [16 cm] long, provided with 4, distant, lower 2 clasping, lanceolate, upper much thinner and free, rachis to 3.6" [9 cm] long, laxly 6 to 7 flowered inflorescence with narrowly lanceolate, twisted, as long as the ovary floral bracts and carrying nodding flowers with a bicallose, glandular-haired lip.
CAUTION!!!! The 2 orchids represented above in photos and drawings are completely different but the first set fits Lindley's type descrition better and fits Dodson & Vasquez's better. The second orchid species set from Brazil fits the drawings and descriptions in the Brazilian references. I am stumped as to which one is correct. The first set by Katia are almost perfect to Dodson's 1989 description and drawing. The second set is very close to Cogniaux's, Hoehne's and Pabst's description and drawings. Since Lindleys minimal description states that the "lip is trilobed with the middle lobe abruptly truncate with acute lateral angles" I feel that Dodson's drawing and Katia's photos are more correct and so the description is compiled from Lindley and Dodson's descriptions and not the Brazilian references. As to what species the Brazilian references describe I cannot say.
