PK Habitat: PKs have been found to grow in the northern side of the Sub-Andean basin, in the Peruvian regions of Amazonas and San Martin, at elevations of 5250-6400 feet (1600– 1950 m.) in tropical cloud forests.  The geological substrate Pk plants grow on is cretacean limestone. The annual rain fall is 40-60", (1000-1500 mm). Average temperature in summer is...
