Dinwiddie County is located along the Appomattox River in southern Virginia west of Petersburg.  The fall line divides the piedmont and coastal plain formations in the eastern third of the county and this is where pitcher plant seepage wetlands containing Sarracenia flava L. and S. purpurea L. occur.  Historical stations occurred along Arthur Swamp (Blaha Bog), Hatcher Run (Burgess station), Rohoic (Old Town) Creek and Rowanty Creek.  The Arthur Swamp site represented the southern station for the New Jersey Rush, Juncus caesariensis Coville.  Over the past ten years new pitcher plant bogs have been discovered on headwaters of Arthur Swamp (Shands Bog), Hatcher Run (Depot Road Bog) and northeast of the town of Addison.  All sites are characterized by moderate relief (1-2% slope) and sand-peat saturated soils.  There are minor floristic differences between sites.  Addison Bog represents the northern most pond pine Pinus serotina Michx. pitcher plant pocosin supporting both Sarracenia species while Shands Bog contains the greatest number of bog rarities.
