Molecular insights into the taxonomy of Glyceria (Poaceae: Meliceae) in North America
Eighteen Glyceria species grow in the United States and Canada, with 16 being native to the region. We used data from morphology and three chloroplast DNA intergenic regions to address taxonomic questions concerning Glyceria in North America, particularly the status of G. declinata, G. occidentalis,...

| description | Eighteen Glyceria species grow in the United States and Canada, with 16 being native to the region. We used data from morphology and three chloroplast DNA intergenic regions to address taxonomic questions concerning Glyceria in North America, particularly the status of G. declinata, G. occidentalis, G. fluitans, G. striata, and G. elata in western North America. The chloroplast data confirmed the presence of two European species, G. declinata and G. fluitans, in western North America. Glyceria occidentalis was exceptional among the taxa studied in having chloroplast genotypes that fell into two different clades, one of which contained G. fluitans and the other the North American species G. leptostachya. The morphological data showed G. occidentalis to be intermediate between G. fluitans and G. leptostachya with respect to their distinguishing characters. Based on these results, we hypothesize that G. occidentalis consists of hybrids between G. fluitans and G. leptostachya. Glyceria elata and G. striata, which have sometimes been treated as a single species, had different chloroplast genotypes, supporting their recognition as distinct taxa. DNA data from all three intergenic regions would be needed for unequivocal identification of the non-hybrid species examined. |
