Putative hybrid species of plant in the genus Crataegus
Crataegus × yosgatica or Crataegus yosgatica is a putative hybrid species of hawthorn.[2] It was thought to be a cross between Crataegus monogyna and C. tanacetifolia.[3] A 2014 molecular and morphological study reduced it to a synonym of Crataegus meyeri.[4]
