DownloadQuercus robur (Latin quercus, "oak" + robur "strength") is the species by which the oak genus is defined, and a member of the white oak section.
Quercus robur is a large deciduous tree, with circumference of grand oaks from 4 m to exceptional 12 m. The Majesty Oak with a circumference of 12.2 m is the thickest tree in Great Britain.
Quercus robur has lobed and very short-stalked leaves 7–14 cm long. Flowering takes place in mid spring, and the fruit, acorns, ripen by the following autumn. The acorns are 2–2.5 cm long, pedunculate (having an acorn-stalk, 3–7 cm) long) with one to four acorns on each peduncle.
Q. robur is very tolerant to soil conditions and the continental climate, but it prefers fertile and well-watered soils. Mature trees tolerate flooding.
It is a long-lived tree, with a large wide spreading crown of rugged branches. While it may naturally live to an age of a few centuries, many of the oldest trees are pollarded or coppiced, both pruning techniques that extend the tree's potential lifespan, if not its health. Two individuals of notable age are the Stelmuze Oak in Lithuania and the Granit Oak in Bulgaria, which are believed to be more than 1500 years old, possibly making them the oldraest oaks in Europe
Within its native range Q. robur is valued for its importance to insectsand other wildlife. Numerous insects live on the leaves, buds, and in the acorns. Q. robur supports the highest biodiversity of insect herbivores of any British plant (>400 spp). The acorns form a valuable food resource for several small mammalsand some birds, notably Eurasian jays. Jays were overwhelmingly the primary propagators of oaks before humans began planting them commercially (and still remain the principal propagators for wild oaks), because of their habit of taking acorns from the umbra of its parent tree and burying them undamaged elsewhere. Mammals, notably squirrels,who tend to hoard acorns and other nuts usually leave them too abused to grow in the action of moving or storing them.
A number of cultivarsare grown in gardensand parks. The most common cultivar is Quercus robur 'Fastigiata', and is the exception among Q. robur cultivars that are generally smaller than the standard tree, growing to between 10–15 m.
Trident Maple is a small to medium-sized deciduous tree reaching a height of 5–20 m with a trunk up to 50 cm diameter. The leaves are in opposite pairs, 2.5–8 cm long (excluding the 2–5 cm petiole) and 3.5–6.5 cm broad, hard, glossy dark green above, paler below, usually with three lobes; on mature trees the lobes forward-pointing and with smooth margins, on young trees with more spreading lobes and serrated margins. The flowers are produced in spring, yellow-green, in pendulous corymbs; they are small, with five greenish sepals and five yellow-white petals about 2 mm long, and eight stamens. The fruit is a samara with two winged seeds, each seed 4–7 mm diameter, with a 15 mm wing; the wings are forward-pointing and often overlapping each other.
It is widely grown in temperate regions as an ornamental tree. It was introduced very early to Japan, where its name translates as "China maple". More recently, it was introduced to Europe and North America in 1896, and is now occasionally grown in parks and large gardens there
Several interesting cultivars have been developed, many of these bear Japanese names. Notable cultivars include 'Goshiki Kaede' (striking pink and green variegation), 'Kifu Nishiki' (roundish, almost un-lobed leaves), 'Mino Yatsubusa' (dwarf with long, narrow leaves) 'Mitsubato Kaede' (distinctive cork-like trunk) and 'Naruto' (strongly incurved leaf surface).
Maples perform best in a sheltered spot with protection from harsh wind and hot afternoon sun. They don't like to dry out too much in summer and if it is particularly hot and dry extra mulch around the roots will be of benefit. Due to the conditions in my garden I grow a range of Maples in large pots very successfully, with regular watering and feeding they can stay in the same pot for several years. Japanese varieties especially "weepers" suit container planting best.

Quercus coccinea is a very popular North American oak with a large, broadly columnar form. Its leaves are a dark green colour which change to a brilliant, scarlet red colour in autumn. It is also known to have the most brilliant autumn colour of all the oaks. It retains some coppery-coloured foliage during winter. It also withstands droughts once established. Deciduous, grows to 7 x 5m.
Scarlet oak is mainly native to the central and eastern United States, where it is widely distributed. It occurs on dry, sandy, usually acidic soils.
The leaves are glossy green, 7–17 cm long and 8–13 cm broad, lobed, with seven lobes, and with deep sinuses between the lobes. Each lobe has 3-7 bristle-tipped teeth. The leaf is hairless (unlike the related pin oak, which has tufts of pale orange-brown down where the lobe veins join the central vein). The common English name is derived from the autumn coloration of the foliage, which contrasts with pin oak foliage which generally turns bronze in autumn.
The acorns are ovoid, 7–13 mm broad and 17–31 mm long, a third to a half covered in a deep cup, green maturing pale brown about 18 months after pollination. The kernel is very bitter.

Mediterranean firs belong to two sections:
i) Section Abies (Abies bornmuelleriana Mattf., A. borisii-regis Mattf., A. cephalonica Loud., A. equi-trojani Asch., A. nebrodensis Lojac and A. nordmanniana Spach.).
ii) Section Piceaster (Abies cilicica de Lannoy, A. marocana Trabut, A. numidica Carrière and A. pinsapo Boissier). They are evergreen conifers growing up to 50 m in height, with straight trunk and pyramidal crown that later turns to flat-topped. The 3-5 buds at the apex of the shoots are conical to ovoid and generally resinous. Leaves are linear, flattened with an acute (A. cephalonica, A. borisii-regis, A. equi-trojani and A. pinsapo) or round (A. cilicica, A. nebrodensis, A. nordmanniana and A. numidica) apex.
The firs are obligate seeders, monoecious and wind-pollinated and their seeds are wind-dispersed. The cones ripen in one season, while abundant seed production occurs only every 3-5 years. They form that span a considerable altitudinal range (600-2000 m) and grow in humid bioclimates.
Mediterranean firs have distributions that are relics of mostly endemic species. The distribution area of most fir species is concentrated in the eastern Mediterranean and the Black Sea region.
Fir wood is generally considered of lesser technical value than pine wood, but is used for carpentry purposes due to its softness and workability. It is also used for general construction, paper, glued and composite wood products, veneer, plywood, panels and poles, as well as fuel wood. A fine oil or turpentine can be distilled from the crude material, while the residue forms a coarse resin named colophony or rosin. Fresh oleoresin is mainly used for pharmaceutical purposes.
Lawson’s false cypress (Chaemocyparis lawsoniana)
These two stately, weeping, pyramidal conifers stand in Hamilton Road, probably planted in the 1970s when the Lockwood homes whose gardens they grace were built by George Veldwjik. It is unusual to see tall conifers in the gardens of Cambridge and they are all the more precious for that. Anyone who has visited Vancouver will have been impressed by the beauty of the large conifers in that city’s private gardens.
Lawsoniana were first found by Europeans growing in Oregon and NW California, from sea level to 1500m, most often along streams. It was named and introduced into cultivation in 1854 by botanists working for the Lawson and Son nursery in Edinburgh, Scotland. Normally Lawsoniana grows to about 60 m but many bigger ones have been felled in USA, some of them very old; in 1965 a still healthy tree was felled which was 75m high, over 5 m in diameter, and displaying 1755 rings.
The wood has a ginger aroma, and is light in colour, strong with a fine, straight grain; it is in demand in Japan for making coffins, and for shrines and temples, and for arrows. It is also used for making stringed instruments as it has high tonal quality.
American Black Walnut (Juglans nigra). Two American black walnut trees stand near the corner of Addison and Shakespeare Streets, one a shapely young tree seen here in glorious autumn yellow, the other bare and well-befitting the description by Hugh Johnson: ‘There can scarcely be a tree that puts on less of a show. It is one of the last bare trees of spring and the first of winter …. It stands looking like a puritan about to close the theatres, [but] what it offers is of the highest quality: the best timber and the best of all nuts.’ While not as good as the nuts of the English walnut, those of the American tree can still be pickled in vinegar, preserved in sugar, made into sauces, oil and liqueurs; they are used in ice cream, and confectionery as well as in salads and meat dishes. The husks produce a very fast, yellow-brown dye, and the ground shells can be used to clean and polish soft metals, plastics, fibreglass, wood and stone. Walnut wood is dark in colour, hard, dense, tight-grained; it gives an excellent polish which is much favoured for fine furniture, and the burrs are used for turning and veneer. Because of its weight and smoothness and especially its resilience to compression along the grain, it is indispensable for gunstocks
