Common Name or Meaning The Two-Winged Ponthieva
Flower Size 1/2" at largest
Found in Colombia, Venezuela, Ecuador and Peru in cloud forests at elevations around 1400 to 2800 meters as a medium to large sized, cool to cold growing terrestrial orchid with 4 to 8 basal, ovate-elliptic, acute to acuminate, gradually narrowing below into the elongate, cuneate, petiolate base leaves that blooms on an erect, terminal, pubescent, 3 1/4" to 5" [8 to 12 cm] long, several to many [8 to 20] flowered inflorescence occuring in the summer in Colombia with scented flowers.
This species and P garayana are very, very similar and may be conspecific but as of yet I do not have good drawings for this species. I await further references to make a final descision.
CAUTION< The determinations of this group [P diptera, P garayana, P tuerckheimii] are very difficult to work with photos as there are just not enough angles of the flowers to get the lip right
