Crataegus apiifolia

Crataegus apiifolia is a name sometimes used for some species of hawthorns. In 1793 Medikus published the name C. apiifolia for a European hawthorn (now included in C. monogyna), but the name is illegitimate under the rules of botanical nomenclature. In 1803 Michaux published the same name for an American species, but that name is also illegitimate, see C. marshallii.
