Genus: Cleistesiopsis

Spreading Pogonia

Cleistesiopsis is a genus of 3 species endemic to eastern North America, formerly included in the genus Cleistes. Although both genera have tubular flowers, the North American species do not produce nectar and offer pollen as a reward or rely on deception to attract pollinators. Other morphological and molecular characters have been used to distinguish the North American species from other members of Cleistes and the genus Cleistesiopsis was established. These orchids have 1 or rarely 2 leaves on their stems, and produce up to 3 rose-pink to white flowers with pink or purple veins on the labellum. The petals are directed forward forming a distinctive tube with the lip and the olive-green or maroon sepals spread away from the main flower. Members of this genus can reproduce asexually by root shoots, sometimes forming large colonies.
