Crataegus laevigata, known as the midland hawthorn, woodland hawthorn or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain (where it is uncommon, and largely confined to the Midlands) and Spain east to the Czech Republic and Hungary. The species name is often spelled C. levigata, but the original orthography is C. lævigata.
It is a large shrub or small tree growing to 8 m (rarely to 12 m) tall, with a dense crown. The leaves are 2–6 cm long and 2–5 cm broad, with 2–3 shallow, forward-pointing lobes on each side of the leaf. The hermaphrodite flowers are produced in corymbs of 6–12, each flower with five white or pale pink petals and two or three styles, and are pollinated by midges. The fruit is a dark red pome 6–10 mm diameter, slightly broader than long, containing 2–3 nutlets.
It is distinguished from the related Common Hawthorn, C. monogyna, in the leaves being only shallowly lobed, with forward-pointing lobes, and in the flowers having more than one styles. However hybrids occur frequently.
