Common Name or Meaning The Bearing Live Young Coilostylis [refers to the growth habit of the plant with keikis]

Flower Size 2 5/8" [6.5 cm]

Found in Colombia, Ecuador, Peru, Bolivia, Brazil and the Guianas at elevations of 190 to 450 meters as a medium sized, hot growing epiphyte that has the strange habit of putting out keikis on top of keikis [see plant photo] and is not uncommon to have three or four sets of plants growing on one inflorescence one stacked above the other.

This species has cylindric pseudobulbs and that is the major difference between this species and the often confused E. purpurescens. It blooms in the spring with a few successively opening flowers, with 3 to 5 open at a time, on a terminal, to 12" [30 cm] long, few to several flowered inflorescence.

This plant is often misnamed as Epidendrum purpurescens/Coilostylis clavatum but that species has compressed pseudobulbs with no keikis on the inflorescence, while C vivipara has cylindrical pseudobulbs and an inflorescence that has a tendency to grow small plantlets after flowering.
