Crataegus monogyna, known as common hawthorn, oneseed hawthorn, or single-seeded hawthorn, is a species of hawthorn native to Europe, northwest Africa and western Asia. It has been introduced in many other parts of the world. It can be an invasive weed.
|Section:||Crataegus sect. Crataegus|
|Series:||Crataegus ser. Crataegus|
Other common names include may, mayblossom, maythorn, quickthorn, whitethorn, motherdie, and haw.
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.
The common hawthorn is a shrub or small tree 5–14 metres (15 to 45 feet) tall, with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear sharp thorns, approximately 12. 5mm (half an inch) long. The leaves are 20 to 40 mm (1 to 1½ inches) 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 10 mm 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 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. However they are inter-fertile and hybrids occur frequently; they are only entirely distinct in their more typical forms.
Crataegus monogyna is one of the most common species used as the "hawthorn" of traditional herbalism. The plant parts used are usually sprigs with both leaves and flowers, or alternatively the fruit ("berries"). Hawthorne has been investigated by evidence-based medicine for treating cardiac insufficiency.
Common hawthorn is extensively planted as a hedge plant, especially for agricultural use. Its spines and close branching habit render it effectively stock- and human-proof, with some basic maintenance. The traditional practice of hedge laying is most commonly practised with this species. It is a good fire wood which burns with a good heat and little smoke.
Numerous hybrids exist, some of which are used as garden shrubs. The most widely used hybrid is C. × media (C. monogyna × C. laevigata), of which several cultivars are known, including the very popular 'Paul's Scarlet' with dark pink double flowers. Other garden shrubs that have sometimes been suggested as possible hybrids involving the common hawthorn, include the various-leaved hawthorn of the Caucasus, which is only very occasionally found in parks and gardens.
The fruit of hawthorn, called haws, are edible raw but are commonly made into jellies, jams, and syrups, used to make wine, or to add flavour to brandy. Botanically they are pomes, but they look similar to berries. A haw is small and oblong, similar in size and shape to a small olive or grape, and red when ripe. Haws develop in groups of two or three along smaller branches. They are pulpy and delicate in taste. In this species (C. monogyna) they have only one seed, but in other species of hawthorn there may be up to five seeds.
Petals are also edible, as are the leaves, which if picked in spring when still young are tender enough to be used in salads. Hawthorn petals are used in the medieval English recipe for spinee, an almond-milk based pottage recorded in 'The Forme of Cury' by the Chief Master-Cook of King Richard II, c. 1390.
An ancient specimen, and reputedly the oldest tree of any species in France, is to be found alongside the church at Saint Mars sur la Futaie, Mayenne. The tree has a height of 9 m (30 feet), and a girth of 265 cm (8'8") (2009). The inscription on the plaque beneath reads: "This hawthorn is probably the oldest tree in France. Its origin goes back to St Julien (3rd century)", but such claims are impossible to verify.
A famous specimen in England was the Glastonbury or Holy Thorn which, according to legend, sprouted from the staff of Joseph of Arimathea after he thrust it into the ground while visiting Glastonbury in the 1st century AD. The tree was noteworthy because it flowered twice in a year, once in the late spring which is normal, but also once after the harshness of midwinter had passed. The original tree at Glastonbury Abbey, felled in the 1640s during the English Civil War, has been propagated as the cultivar 'Biflora'. A replacement was planted by the local council in 1951, but was cut down by vandals in 2010.
The oldest known living specimen in East Anglia, and possibly in the United Kingdom, is known as The Hethel Old Thorn, and is located in the churchyard in the small village of Hethel, south of Norwich, in Norfolk. It is reputed to be more than 700 years old, having been planted in the 13th century.
The hawthorn is associated with Faerie in Ireland, and as such is not disturbed by those who believe in the danger fairies traditionally represent.

Plaster's Green Meadows (grid reference ST532611) is a 4.3 hectare biological Site of Special Scientific Interest near the village of Nempnett Thrubwell, Bath and North East Somerset, notified in 1989.
This is an area of unimproved and traditionally managed species-rich meadows which support a neutral grassland community of a
type which is now rare throughout Britain. The site is situated on the slopes fringing the Lias Tablelands and is underlain by Rhaetic clays and, lower down the slope Keuper Red Marl. The slowly permeable clay soils are slightly calcareous in nature and this is reflected in elements of the flora.
The site is characterised by the nationally rare Common Knapweed (Centaurea nigra) and Crested Dog’s-tail (Cynosurus cristatus) and dominant grasses include Sweet Vernal-grass (Anthoxanthum odoratum), Crested Dog’s-tail and Yorkshire Fog (Holcus lanatus), while Quaking Grass (Briza media) and Yellow Oat-grass (Trisetum flavescens) are also frequent.
There is a high component of herb species throughout the meadows including Saw-wort (Serratuta tinctoria), Dyer’s Greenweed (Genista tinctoria), Common Knapweed, Pepper-saxifrage (Silaum silaus), Devil’s-bit Scabious (Succisa pratensis), Betony (Stachys officinalis) and Spiny Restharrow (Ononis spinosa). The calcareous nature of the soil is reflected by the presence of Cowslip (Primula veris), Fairy Flax (Linum catharticum), Glaucous Sedge (Carex flacca), Lady’s Bedstraw (Galium verum) and occasional Salad Burnet (Sanguisorba minor).
The meadows are bounded by hedges supporting numerous species including Hawthorn (Crataegus monogyna), Wych Elm (Ulmus glabra), English Elm (Ulmus procera), Hazel (Corylus avellana) and Field Maple (Acer campestre). Hedgerow trees include Ash (Fraxinus excelsior), Sweet Chestnut (Castanea sativa), Holly (Ilex aquifolium) and Oak (Quercus spp.).Procyanidin B2
Procyanidin B2 is a B type proanthocyanidin. Its structure is (−)-Epicatechin-(4β→8)-(−)-epicatechin.
Procyanidin B2 can be found in Cinchona pubescens (Chinchona, in the rind, bark and cortex), in Cinnamomum verum (Ceylon cinnamon, in the rind, bark and cortex), in Crataegus monogyna (Common hawthorn, in the flower and blossom), in Uncaria guianensis (Cat's claw, in the root), in Vitis vinifera (Common grape vine, in the leaf), in Litchi chinensis (litchi, in the pericarp), in the apple, and in Ecdysanthera utilis.Procyanidin B2 can be converted into procyanidin A2 by radical oxidation using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals under neutral conditions.Procyanidin B2 has been shown to inhibit the formation of the advanced glycation end-products pentosidine, carboxymethyllysine (CML), and methylglyoxal (MGO).Spuleria
Spuleria is a genus of moths of the family Elachistidae. It contains only one species Spuleria flavicaput, which is found in most of Europe and Anatolia.
