Oak Galls
Oak apple or oak gall is the common name for a large, round, vaguely apple-like gall commonly found on many species of oak. Oak apples range in size from in diameter and are caused by chemicals injected by the larva of certain kinds of gall wasp in the family Cynipidae. The adult female wasp lays single eggs in developing leaf buds. The wasp larvae feed on the gall tissue resulting from their secretions, which modify the oak bud into the gall, a structure that protects the developing larvae until they undergo metamorphosis into adults. Considerable confusion exists in the general literature between the oak apple and the oak marble gall. The oak marble is frequently called the oak apple due to the superficial resemblance and the preponderance of the oak marble gall in the wild. Other galls found on oak trees include the oak artichoke gall and the acorn cup gall, but each of these has its own distinctive form. Some common oak-apple-forming species are the ''Biorhiza ...

Oak Apples - Keila
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech Beech (''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, ''Engleriana'' and ''Fagus''. The ''Engle ... family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably ''Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from temperateness, cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 9 ...

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Ro ...

Pineapple Gall
The Pineapple gall adelgid (''Adelges abietis'') is a type of conifer-feeding insect that forms pineapple-shaped plant galls on its host species, commonly Norway and Sitka spruce. The adelgids (genus ''Adelges'') are pear-shaped, soft-bodied green insects with long antennae, closely related to the aphid. ''Adelges'' lays up to one hundred eggs at a time, one on each needle. ''Adelges abietis'' (Linnaeus, 1758) is one of the most common species; synonyms are ''A. gallarum-abietis'', ''Chermes abietis'' and ''Sacciphantes abietis''. The pineapple or pseudocone gallDarlington, Arnold (1975) ''The Pocket Encyclopaedia of Plant Galls in Colour.'' Pub. Blandford Press. Poole. . P. 114. is a type of insect-formed gall, or abnormal outgrowth of plant tissue, that develops as a chemically induced distortion of needles, observed mostly on Norway spruce and Sitka spruce.

Knopper Gall
''Andricus quercuscalicis'' is a gall wasp species inducing knopper galls. Knopper galls develop as a chemically induced distortion of growing acorns on pedunculate oak (''Quercus robur'' L.) trees, caused by gall wasps, which lay eggs in buds with their ovipositor. The gall thus produced can greatly reduce the fecundity of the oak host, making this gall potentially more of a threat to the reproductive ability of the tree than those that develop on leaves, buds, stems, etc. The Turkey oak (''Quercus cerris'' L.), introduced into Britain in 1735, is required for the completion of the life cycle of the gall. The knopper is a recent introduction to the British Isles, first arriving in the 1960s and now found throughout England, Wales and as far north as Scotland; first occurring for example in 2007 at Eglinton Country Park in North Ayrshire. The physical appearance of the gall The large 2 cm gall growth appears as a mass of green to yellowish-green, ridged, and at first stick ...

Quercus Garryana
''Quercus garryana'' is an oak tree species of the Pacific Northwest, with a range stretching from southern California to southwestern British Columbia. It is commonly known as the Oregon white oak or Oregon oak or, in Canada, the Garry oak. It grows from sea level to an altitude of in the northern part of its range, and from in the south of the range in California. The eponymous Nicholas Garry was deputy governor of the Hudson's Bay Company. Description It is typically of medium height, growing slowly to around and occasionally as high as 100 ft, or in shrub form to tall. The trunks grow to thick, exceptionally . The Bark (botany), bark is gray and fissured. It has the characteristic oval profile of other oaks when solitary, but is also known to grow in groves close enough together that crowns may form a canopy. The leaves are deciduous, long and 1–3 inches broad, with 3–7 deep lobes on each side, darker green on top and finely haired below. The flowers are catk ...

The Royal Oak
The Royal Oak is the English oak tree within which the future King Charles II of England hid to escape the Roundheads following the Battle of Worcester in 1651. The tree was in Boscobel Wood, which was part of the park of Boscobel House. Charles told Samuel Pepys in 1680 that while he was hiding in the tree, a Parliamentarian soldier passed directly below it. The story was popular after the Restoration, and is remembered every year in the English traditions of Royal Oak Day. Numerous large slipware dishes (known as 'chargers') depicting the Boscobel Oak were made by the Staffordshire potter Thomas Toft. The oak tree is shown being supported by the Lion and Unicorn, with the king's face peeping from the branches. History After the defeat of Charles' Royalist army at the hands of Oliver Cromwell's New Model Army, the King fled with Lord Derby, Lord Wilmot and other royalists, seeking shelter at the safe houses of White Ladies Priory and Boscobel House. Initially, Char ...

English Civil War
The English Civil War (1642–1651) was a series of civil wars and political machinations between Parliamentarians (" Roundheads") and Royalists led by Charles I ("Cavaliers"), mainly over the manner of England's governance and issues of religious freedom. It was part of the wider Wars of the Three Kingdoms. The first (1642–1646) and second (1648–1649) wars pitted the supporters of King Charles I against the supporters of the Long Parliament, while the third (1649–1651) saw fighting between supporters of King Charles II and supporters of the Rump Parliament. The wars also involved the Scottish Covenanters and Irish Confederates. The war ended with Parliamentarian victory at the Battle of Worcester on 3 September 1651. Unlike other civil wars in England, which were mainly fought over who should rule, these conflicts were also concerned with how the three Kingdoms of England, Scotland and Ireland should be governed. The outcome was threefold: the trial of and ...

Charles II Of England
Charles II (29 May 1630 – 6 February 1685) was King of Scotland from 1649 until 1651, and King of England, Scotland and Ireland from the 1660 Restoration of the monarchy until his death in 1685. Charles II was the eldest surviving child of Charles I of England, Scotland and Ireland and Henrietta Maria of France. After Charles I's execution at Whitehall on 30 January 1649, at the climax of the English Civil War, the Parliament of Scotland proclaimed Charles II king on 5 February 1649. But England entered the period known as the English Interregnum or the English Commonwealth, and the country was a de facto republic led by Oliver Cromwell. Cromwell defeated Charles II at the Battle of Worcester on 3 September 1651, and Charles fled to mainland Europe. Cromwell became virtual dictator of England, Scotland and Ireland. Charles spent the next nine years in exile in France, the Dutch Republic and the Spanish Netherlands. The political crisis that followed Cromwell's death in 1 ...

English Restoration
The Restoration of the Stuart monarchy in the kingdoms of England, Scotland and Ireland took place in 1660 when King Charles II returned from exile in continental Europe. The preceding period of the Protectorate and the civil wars came to be known as the Interregnum (1649–1660). The term ''Restoration'' is also used to describe the period of several years after, in which a new political settlement was established. It is very often used to cover the whole reign of King Charles II (1660–1685) and often the brief reign of his younger brother King James II (1685–1688). In certain contexts it may be used to cover the whole period of the later Stuart monarchs as far as the death of Queen Anne and the accession of the Hanoverian King George I in 1714. For example, Restoration comedy typically encompasses works written as late as 1710. The Protectorate After Richard Cromwell, Lord Protector from 1658 to 1659, ceded power to the Rump Parliament, Charles Fleetwood and J ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ...

Oak Apple Day
Restoration Day, more commonly known as Oak Apple Day or Royal Oak Day, was an English, Welsh and Irish public holiday, observed annually on 29 May, to commemorate the restoration of the Stuart monarchy in May 1660. In some parts of England the day is still celebrated. It has also been known as Shick Shack Day, or Oak and Nettle Day. In 1660, the English Parliament passed into law "An Act for a Perpetual Anniversary Thanksgiving on the Nine and Twentieth Day of May", declaring 29 May a public holiday "for keeping of a perpetual Anniversary, for a Day of Thanksgiving to God, for the great Blessing and Mercy he hath been graciously pleased to vouchsafe to the People of these Kingdoms, after their manifold and grievous Sufferings, in the Restoration of his Majesty..." The public holiday was abolished under the Anniversary Days Observance Act 1859, but the date retains some significance in local and institutional customs. It is, for example, still observed as Founder's Day by the R ...

Michaelmas Day
Michaelmas ( ; also known as the Feast of Saints Michael, Gabriel, and Raphael, the Feast of the Archangels, or the Feast of Saint Michael and All Angels) is a Christianity, Christian festival observed in some Western liturgical year, liturgical calendars on 29 September, and on 8 November in the Eastern tradition.
