Populus

                 Populus is a genus of 25–35 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar, aspen, and cottonwood. The genus has a large genetic diversity, and can grow from anywhere between 15–50 m (50 to 165 ft) tall, with trunks of up to 2.5 m (8 ft) diameter. 
                 The genus Populus has traditionally been divided into six sections on the basis of leaf and flower characters. These are: Populus section Populus – aspens and White Poplar, Populus section Aigeiros – black poplars, some of the cottonwoods, Populus section Tacamahaca – balsam poplars, Populus section Leucoides – necklace poplars or bigleaf poplars, Populus section Turanga – subtropical poplars, Populus section Abaso – Mexican poplars.

Olive tree

               The olive tree (Olea europaea) is a species of small tree in the family Oleaceae, native to the coastal areas of the eastern Mediterranean Basin as well as northern Iraq, and northern Iran at the south of the Caspian Sea. Olives like hot weather, and temperatures below −10 °C (14 °F) may injure even a mature tree. They tolerate drought well, thanks to their sturdy and extensive root system. Olive trees can live for several millennia. Olives grow very slowly, and over many years the trunk can attain a considerable diameter. The trees rarely exceed 15 metres (49 ft) in height, and are generally confined to much more limited dimensions by frequent pruning. 
                There are six natural subspecies of Olive tree: Olea europaea subsp. europaea, Olea europaea subsp. cuspidata, Olea europaea subsp. guanchica, Olea europaea subsp. cerasiformis, Olea europaea subsp. maroccana, Olea europaea subsp. laperrinei.

Willow

             Willows (salix) found primarily on moist soils in cold and temperate regions of the Northern Hemisphere. 
             Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to life, and roots readily grow from aerial parts of the plant. 
             Willows are dioecious, with male and female flowers appearing as catkins on different plants; the catkins are produced early in the spring, often before the leaves, or as the new leaves open.

Bamboo tree

               Bamboo (Bambuseae) is a tribe of flowering perennial evergreen plants in the grass family Poaceae, subfamily Bambusoideae, tribe Bambuseae. Bamboo species are found in diverse climates, from cold mountains to hot tropical regions. They occur across East Asia, from 50°N latitude in Sakhalin[citation needed] through to Northern Australia, and west to India and the Himalayas. They also occur in sub-Saharan Africa, and in the Americas from the mid-Atlantic United States south to Argentina and Chile, reaching their southernmost point anywhere, at 47°S latitude. 
                Giant bamboos are the largest members of the grass family. In bamboos, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. Bamboo is one of the fastest-growing plants on Earth, with reported growth rates of 100 cm (39 in) in 24 hours.

Coconut tree

              The coconut palm (Cocos nucifera) is a member of the family Arecaceae (palm family). It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. 
              The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (150 cm to 250 cm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth. Coconut palms are grown in more than 80 countries of the world, with a total production of 61 million tonnes per year.

Apple tree

            Apple tree (Malus domestica) is the pomaceous fruit in the rose family (Rosaceae). It is one of the most widely cultivated tree fruits, and the most widely known of the many members of genus Malus that are used by humans. Apples grow on small, deciduous trees. The tree originated in Western Asia, where its wild ancestor, Malus sieversii, is still found today. Apples have been grown for thousands of years in Asia and Europe, and were brought to North America by European colonists. 
             The proverb "An apple a day keeps the doctor away.", addressing the health effects of the fruit, dates from 19th century Wales. Research suggests that apples may reduce the risk of colon cancer, prostate cancer and lung cancer.

Maple (Acer)

               Maple (Acer) is a genus of trees or shrubs. Maples are variously classified in a family of their own, the Aceraceae, or together with the Hippocastanaceae included in the family Sapindaceae. Modern classifications, including the Angiosperm Phylogeny Group system, favour inclusion in Sapindaceae. The type species of the genus is Acer pseudoplatanus (Sycamore maple). 
               Most maples are trees growing to 10 – 45 m (30 – 145 ft) in height. Others are shrubs less than 10 metres tall with a number of small trunks originating at ground level. Most species are deciduous, but a few in southern Asia and the Mediterranean region are evergreen.

Walnut tree

            The Walnut tree (genus Juglans) is among the most versatile hardwoods on the planet. In addition to yielding exceptional tasting nuts, its timber is treasured by carpenters and sculptors alike. The Walnut tree's wide array of uses also makes it a popular pick for homeowners looking to decorate their properties with a practical and profitable specimen.   
            There are nearly two-dozen different types of Walnut trees in the world, though most are native to the United States. Among the most popular are: Black Walnut, Butternut, Arizona Walnut, Japanese Walnut, Bolivian Walnut, Southern California Walnut, Northern California Walnut, West Indian Walnut, Manchurian Walnut, Andean Walnut, English Walnut and Little Walnut.

Plum

             A Plum tree (gage) is a stone fruit tree in the genus Prunus, subgenus Prunus. The subgenus is distinguished from other subgenera (peaches, cherries, bird cherries, etc.) in the shoots having a terminal bud and solitary side buds (not clustered), the flowers in groups of one to five together on short stems, and the fruit having a groove running down one side and a smooth stone (or pit). 
           The subgenus Prunus is divided into three sections: 
- sect. Prunus (Old World plums)- leaves in bud rolled inwards; flowers 1-3 together; fruit smooth, often wax-bloomed;
- sect. Prunocerasus (New World plums) - leaves in bud folded inwards; flowers 3-5 together; fruit smooth, often wax-bloomed; 
- sect. Armeniaca (apricots) - leaves in bud rolled inwards; flowers very short-stalked; fruit velvety; treated as a distinct subgenus by some authors.

Beech tree

           Beech tree (Fagus) is a genus of ten species of deciduous trees in the family Fagaceae, native to temperate Europe, Asia and North America. F. sylvatica is the most commonly cultivated, although there are few important differences between species aside from detail elements such as leaf shape. Beeches may get to as tall as 27 meters and 18 meters in width, although usually much smaller.
           There are 11 species of beech tree: Fagus crenata (Japanese Beech), Fagus engleriana (Chinese Beech), Fagus grandifolia (American Beech), Fagus hayatae (Taiwan Beech), Fagus japonica (Japanese Blue Beech), Fagus longipetiolata (South Chinese Beech), Fagus lucida (Shining Beech), Fagus mexicana (Mexican Beech or Haya), Fagus orientalis (Oriental Beech), Fagus sylvatica (European Beech), Fagus taurica (Crimean beech).

Fir tree

             Fir tree (Abies) is a genus of 48–55 species of evergreen coniferous tree in the family Pinaceae. It is found through much of North and Central America, Europe, Asia, and North Africa, occurring in mountains over most of the range. Firs are most closely related to the genus Cedrus (cedar); Douglas-firs are not true firs, being of the genus Pseudotsuga. 
              All native species reach heights of 10–80 m (30–260 ft) tall and trunk diameters of 0.5–4 m (2–12 ft) when mature.
              Nordmann Fir, Noble Fir, Fraser Fir and Balsam Fir are popular Christmas trees, generally considered to be the best for this purpose, with aromatic foliage that does not shed many needles on drying out.

Sweet chestnut

           The Sweet Chestnut (Castanea sativa) is a species of the flowering plant family Fagaceae. Originally native to southeastern Europe and Asia Minor, it is now widely dispersed throughout Europe and parts of Asia, such as the lower Himalayas and other temperate parts of the Indian Subcontinent. The trees are hardy, long lived and well known for their chestnuts, which are used as an ingredient in cooking.

           Castanea sativa is a medium-sized to large deciduous tree attaining a height of 20–35 m with a trunk often 2 m in diameter. The oblong-lanceolate, boldly toothed leaves are 16–28 cm long and 5–9 cm broad. The flowers of both sexes are borne in 10–20 cm long, upright catkins, the male flowers in the upper part and female flowers in the lower part.

Banana tree

         Banana is one of the oldest cultivated plants, beeing the common name for herbaceous plants of the genus Musa and for the fruit they produce. Worldwide, there is no sharp distinction between "bananas" and "plantains". They are native to tropical South and Southeast Asia, and are likely to have been first domesticated in Papua New Guinea. They are grown in at least 107 countries beeing cultivated throughout the tropics primarily for their fruit.
          Almost all modern edible parthenocarpic bananas come from two wild species – Musa acuminata and Musa balbisiana. 
          The banana plant is the largest herbaceous flowering plant. The plants are normally tall and fairly sturdy and are often mistaken for trees, but their main or upright stem is actually a pseudostem that grows 6 to 7.6 metres (20 to 24.9 ft) tall, growing from a corm. Each pseudostem can produce a single bunch of bananas. After fruiting, the pseudostem dies, but offshoots may develop from the base of the plant. Many varieties of bananas are perennial.
