Crataegus monogyna, known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and Western Asia, but has been introduced in many other parts of the world.

Names

This species is one of several that have been referred to as Crataegus oxyacantha, a name that has been rejected by the botanical community as too ambiguous. In 1793, Medikus published the name C. apiifolia for a European hawthorn now included in C. monogyna, but that name is illegitimate under the rules of botanical nomenclature.

Other common names include may, mayblossom, maythorn, (as the plant generally flowers in May) quickthorn, whitethorn, motherdie, and haw.

Description

The common hawthorn is a shrub or small tree up to about 10 metres (33 feet) tall, with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear sharp thorns, about 12.5 millimetres (1⁄2 inch) long. The leaves are 20 to 40 mm (3⁄4 to 1+1⁄2 in) long, obovate, and deeply lobed, sometimes almost to the midrib, with the lobes spreading at a wide angle. The upper surface is dark green above and paler underneath.

The hermaphrodite flowers are produced in late spring (May to early June in its native area) in corymbs of 5–25 together; numerous red stamens and a single style; they are moderately fragrant. The flowers are white, frequently pink pollinated by midges, bees, and other insects, and later in the year bear numerous haws. The haw is a small, oval, dark red fruit about 10 mm long, berry-like, but structurally a pome containing a single seed. Haws are important for wildlife in winter, particularly thrushes and waxwings; these birds eat the haws and disperse the seeds in their droppings.

The common hawthorn is distinguished from the related but less widespread Midland hawthorn (C. laevigata) by its more upright growth, the leaves being deeply lobed, with spreading lobes, and in the flowers having just one style, not two or three. They are interfertile, however, so hybrids occur frequently; they are only entirely distinct in their more typical forms.
