Drymocallis is a genus of plants formerly (and sometimes still) included with the typical cinquefoils (Potentilla). It contains three species known or suspected to be protocarnivorous, but more cinquefoils might eventually be moved here:

• Drymocallis arguta – Tall Cinquefoil, Cream Cinquefoil
• Drymocallis glandulosa (Lindl.) Rydb. – Sticky Cinquefoil
  • Drymocallis glandulosa ssp. ashlandica (Greene) Soják
  • Drymocallis glandulosa ssp. glandulosa
  • Drymocallis glandulosa var. intermedia
• Drymocallis rupestris (L.) Soják – Rock Cinquefoil

Internal transcribed spacer DNA sequence data suggests they are more closely related to Chamaerhodos and Dasiphora than to species such as Creeping Cinquefoil (P. reptans) which make of the bulk of Potentilla.
