Thickets of speckled alder consist of numerous discrete clumps of stems. All stems in a single clump are part of a single genetic individual, but a genet could comprise more than one clump. In 4 alder populations in central New York, nearest neighbor analysis revealed that genotypes were distributed randomly. Although alder is capable of forming root suckers and offsets, lateral expansion of genets is apparently ineffective. Apparently, spatial distribution of genetic individuals within alder thickets is not influenced by clonal growth or by other factors acting to cause patterns in the genetic structure of plant populations. -from Author
