reneerenge van Buren233 stewart C SandersoSandersonsandersonlsanderson1nl1 and kimball T harper2harpere ABSTRACT relationships within between and among the anthemideae genera sphaeromeria artemisia and tanacetum were investigated using 238 randomly amplified polymorphic DNA RAPD markers obtained from twenty lomer10 mer primers amplified on genomic DNA forty one populations from 16 taxa 15 species were studied jaccard s coefficient of similarity and UPGMA clustering analysis were used to construct phonophenogramsphonogramsgrams T tests were used to make comparisons between samples at various systematic levels DNA markers were 75 similar for conspecific populations sixteen sphaeromeriasphaeromena populations 5 species showed an average interspecific similarity of 21 interspecific similarity among 23 artemisia populations 8 species with 2 subspecies of A tntritrldentata included averaged 27 two tanacetum species 1 I1 population each were 89 similar the high similarity of the tanacetum species was in the range of observed values for conspecific populations indeed those 2 species T vulgare and T boreale have been considered conspecific by some authors the 3 subgenerasub genera of artemisia studied artemisia dracunculus and tndentataetridentataeTridentatae formed separate groups in comparisons among the genera sphaeromeriasphaeromena was 18 similar to artemisia more similar to subgenus tri- dentdentataeatae than the other artemisia subgenerasub genera interintergenericmtergenencgeneriegeneric comparisons of sphaeromeriasphaeromena and artemisia and artemisia and tanacetum each were found to be 7 similar to each other thus based on DNA markers sphaeromeriasphaeromena is more similar to artemisia than it is to tanacetum which supports previously established morphological distinctions sphaeromeriasphaeromena potentilloides may be misplaced in the genus sphaeromenasphaeromeria based on DNA marker resultsi it is likely that north american anthemideae are circumboreal derivatives of ancestral eurasian stock and that sphaeromeriasphaeromena is derived from an artemisia likeilke ancestor key words sphaeromenaspbaeromeria artemisia tanacetum anthemideae
