Sabatia kennedyana explained
Sabatia kennedyana is a species of flowering plant in the gentian family known by the common name Plymouth rose gentian. It is native to eastern North America. It has a disjunct distribution, occurring in Nova Scotia,[1] Massachusetts, Rhode Island, Virginia,[2] North Carolina, and South Carolina.[3]
Distribution
Sabatia kennedyana grows in wetlands, particularly lakes and ponds on the Atlantic coastal plain.[4] It grows in areas with fluctuating water levels and other forms of natural disturbance, such as ice scour, which eliminate competing vegetation.[5] [6] It is a poor competitor with other plants.[7] [2]
Description
Sabatia kennedyana is a perennial herb with stolons tipped with basal rosettes of leaves. The flower is pink with a white or yellow center.[3] It may be 5 centimeters wide, with 9 to 11 petals.[2]
Taxonomy
Sabatia kennedyana was considered by Ahles to be a variety of Sabatia dodecandra.
Conservation
Sabatia kennedyana is threatened by shoreline development, recreational activity, off-road vehicles, construction of hydroelectric dams,[3] pollution, and poaching.[2]
