Discussion | Gaylussacia bigeloviana has been confused with G. dumosa; there are points of difference, including plant height, corolla size, vestiture, habitat, and the northeastern-centered range of G. bigeloviana. Occurrences in North Carolina are in large, peat-based pocosins that lie mostly within Carolina bay geomorphological formations. The single South Carolina population occurs in an Atlantic white cedar wetland. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Gaylussacia brachycera is a dwarf evergreen shrub that forms large, solid-mat, self-sterile colonies, each one appearing to consist of a single clone that may extend over more than one hectare. One colony in Perry County, Pennsylvania, is about 1.5 kilometers wide; it appears to be a single clone that is over 12,000 years old and has been labeled as the oldest living thing in the world.
