Genus: Crataegus L.
Species: Crataegus monogyna Jacq.
English Name: Common hawthorn or Single-seeded hawthorn.
The Common Hawthorn is a shrub or small tree 5–14 m tall, with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear sharp thorns, 1 to 1.5 cm long. The leaves are 2–4 cm 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; each flower is about 1 cm diameter, and has five white petals, numerous red stamens, and a single style; they are moderately fragrant. The flowers are 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 1 cm 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. However they are inter-fertile and hybrids occur frequently; they are only entirely distinct in their more typical forms.

Perennial shrubs or small trees. The stems reach 8 m in height, with rounded or broadly pyramidal crown. Shoot nude or early short fibrous. Young twigs reddish brown, the older gray-brown. Thorns relatively few, from 0.5 to 1.5 (2) cm long or absent, rarely leafy. Leaves vary widely as a general shape, size and cutting the lamina itself ; typically 6 - 7 cm long, a wide rounded to broadly rhombic, at the base of the most frequently wedge, rarely rounded, even cut off; shares of lamina 3 - 7, asymmetric, shorter or longer, narrower or wider, the top most stupid, entire or incorrect sharply toothed; shiny on top, dark green, pale below, usually with a thin wax coating, with or without fine hairs (usually veins). Blossoms usually multiblossom (18 blossoms) upright shields in diameter about 5 cm; blossom stems well developed, naked or with rare face cloth; blossoms 8 - 15 mm in diameter. A calyx dish (hipantiy) and sepals naked or with rare hairs; sepals in fruit diverted sideways. Petals white, rounded with short small nail. Stamens usually 20. The bar only one in some cases - and very rare cases seldom - 2. Fruit broadly ovate or nearly spherical, 6 - 10 cm long, light to dark red, with one stone. volatility

Economic importance. In the past, ordinary hawthorn was widely used by man. Blossms, seeds, fruits, bark, wood and roots are used for different purposes - for surrogate coffee, to add to the flour for bread, to obtain brandy, for dyeing wool and cotton fabrics, different joinery, too much in folk medicine for the treatment of various diseases, the creation of a variety of garden flowers and leaves races for decorative purposes.
Now its use is much more limited. The blossoms and leaves contain krategova acid, sitosterol, purine derivatives, choline, isoamylamine, various alkylamine etc., So is used in folk medicine and ofi¬tsialnata to enhance cardiac insomnia and nervousness, with shortness of breath, angina pectoris and etc. Artificially created human forms, as: f. flore rosea hort. (with pink corolla), f. flore roseo-pleno hort. (with pink leafy whorl), f. flore rubro hort. (red corolla), f. flore rubro-pleno (red leafy whorl), f flore albo-pleno hort. (white leafy whorl), etc., are grown in parks and gardens (and even in the streets) as ornamental trees.
