Insights on a rare species, 'Geum atlanticum', new data to differentiate from 'Geum sylvaticum'

Geum atlanticum is a species described from North Africa and later found in Southern Iberian Peninsula. However, according to Flora iberica taxonomic treatment, it has been considered synonymous with G. sylvaticum, mainly distributed by Southeast of France, Peninsula, Africa, sharing part the distribution range habitat. In this work, herbarium specimens both sylvaticum were revised evaluate morphological differences. Furthermore, nuclear ribosomal ITS spacer was sequenced study phylogenetic relationships among species. The indicated clear differences analysis suggests that sister sylvaticum. shared several mutations other number populations relatively low so its conservation status further inclusion lists threatened plants have evaluated work.
