Did you know?
The common name "Cinquefoil" in the Middle English Dictionary is described as "Pentafilon" (From Greek Pentaphyllon) influenced by foil, a leaf. The word is derived from Old French cinc, Middle English cink and ultimately Latin quinque, all meaning "five", and feuille and foil/foille which mean "leaf". Formerly this term referred to five-leaved plants in general. In medieval times, the word "cinquefoil" was used almost exclusively in England. In France, the genus was called quintefeuille, first attested in Normandy and Brittany in the 11th century (Wikipedia contributors). The species name means strange or paradoxical and comes from the unusual prominent corky enlarged bases of the carpels (Fernald 1970).

State Ranking Justification [-]
There are four existing populaitions but they are all small with fewer than 30 plants each. There are six historical occurrences from the late 1800s to 1917. Most of these have not been surveyed again.
