Polygonaceae A.L. de Jussieu. Common name: Smartweed Family.

Key to Polygonaceae

A family of about 50 genera and 1100-1200 species, trees, shrubs, vines, and herbs, cosmopolitan, but especially north temperate. Recent changes in the circumscription of various genera (including Polygonum, Persicaria, Fallopia, etc.) have received strong support from molecular phylogenetic studies (Kim & Donoghue 2008; Lamb Frye & Kron 2003; Schuster, Reveal, & Kron 2011; Zhang et al. 2023).

  2. If you opt out of including email, please be as specific as possible (e.g., which photo is incorrect?)
  3. Please do not submit questions asking to identify plants or about horticultural topics (e.g., how do I control an invasive plant in my garden?). Instead, those questions can be submitted here for the Carolinas region only.
  4. Please do not send us feedback about unkeyed species as this work is ongoing.
  5. Please allow time for flora edits to show in our next data release. We greatly appreciate your feedback but may require extra time to research complicated taxonomic issues.
