Acer rubrum – Red Maple

Acer rubrum commonly known as Red Maple also known as swamp Maple or Soft Maple is native to Eastern and Central North America. Red maple is one of the best named of all trees. It is generally easy to identify for its highly changeable in morphological characteristics.

Red Maple is a medium to large growing tree is growing 18 – 27 m (60 – 90 ft) in height, but exceptionally grows over 35 m (116 ft) in height. It is spread is about 12 m (40 ft) with a rounded to oval crown. The trunk diameter can range 46-76 cm (18-30 in), depending on the growing conditions. It is a slow growing tree, within 10 years it may grow about 6 m (20 ft) tall. It grows faster than Norway Maples and Sugar Maples, but slower than Silver Maple.

A. rubrum is a deciduous tree. The leaves are green in color and turned into red in autumn but can also become yellow or orange on some of leaves. They are typically 5 – 10 cm (2 – 4 in) long and same as wide, with 3 – 5 palmate lobes with a serrated margin. The sinuses are typically narrow, but the leaves can display important variation. The top side of the leaves are light green and the down side is whitish and can be either sea-blue or hairy. The leaf stalks are up to 10 cm (4 in) long and usually red in color.

The twigs are reddish in color and partially shiny with small lenticels. Midget shoots are present on many branches. The buds are normally blunt and greenish to reddish in color, usually with several loose scales. The lateral buds are slightly stalked and in addition there may be collateral buds present as well. The buds form in fall and winter and are often visible from a distance due to their reddish tint.

The flowers of Red Maple are appear in spring generally coming before the new leaves. The flowers usually unisexual, with male and female flowers blooming in individual sessile clusters, although sometimes they are also bisexual. The considered Polygamodioecious by itself that meaning some flowers individuals are male, some are female, and some flowers are monoecious. For the Climate condition, the Red Maple tree sometimes can change from male to female or male to hermaphroditic, or hermaphroditic to female. The tree usually start blooming when it grow about 8 years old but it significantly varies between tree to tree some trees star blooming when 4 years old. The flowers are red in color, with 5 small petals and 5 lobed calyx borne in hanging clusters, usually at the twig tips. They are lineal to oblong in shape with pubescent. The feminine flowers have one pistil formed from two fused carpels with a glabrous superior ovary and two long styles that protrude beyond the calyx. The staminate flowers contain 4 – 12 stamens, sometime with 8.

The fruit is a samara 1.5 – 2.5 cm in long that grows in pairs with somewhat divergent wings at an angle of 50 to 60 degrees.  They are borne on long slender stems and are variable in color from light brown to reddish. They ripen from April through early June, before even the leaf development is altogether complete. After they reach maturity, the seeds are dispersed for a 1 to 2 week period from April through July.

The bark of young trees is smooth, silvery-gray becoming scaly and dark with age and older branches and trunk are covered with scaly gray brown bark.

Red maple is a wonderful ornamental tree for its attractive foliage. It is cultivate as ornamental tree in the urban road side and park.

Quercus rubra - Red Oak

Quercus rubra common name is Red Oak. It is graceful round-headed tree with light grey bark, is one of the several North AmericanRed Oaks which have been planted in Europe as a amenity tree on account of the beauty of its autumn foliage. It grows 27-45 m (90-150 ft) in height. More recently it has been planted experimentally for it timber.

The young shoots are rather stout, often five-sided and olive-green to reddish-brown. The brown winter buds are alternately arranged, but towards the tip of the twigs they form clusters. The leaves are larger than those of European native Oaks and have sharply angled lobes. They vary in size and shape and the vein of each lobe projects as a bristle beyond the point. At first the leaves are a pale yellow, later green, and in autumn they turn a dull to rich red-brown.

The flowers of both sexes appear on the same tree in May. The male catkins are yellowish-green, long and sometimes very numerous; the female flowers are shortly stalked. The acorns, which do not mature until the second year, are dumpy and flat-based, standing in shallow cups.

The light grey bark remains smooth for a long time. Only after many years does it develop a slightly rough surface. The wood is open textured, with large pores, and lacks the strength and durability of the native Oaks. It will probably be used for cheaper furniture and flooring. The tree grows fast, even of soils of moderate fertility and plays a small role in European forestry.

Rafflesia arnoldii - Corpse Flower

Rafflesia arnoldii, common name is Corpse Flower. It is native to Indonesia and it is endemic to the rainforests of Borneo and Sumatra. It is noted for producing the largest individual flower on earth. It has no leaf, stem, root and it is a nonphotosynthetic plant, these plants live as parasites inside a host plant, a woody vine related to grapes. It has even been proposed that they are not flowering plants at all, it is a fungi. It is one of the three national flowers of Indonesia. It was recognized as a national “rare Flower”. It grows up to 1 m ( 3.3 ft) in diameter and weight up to 11 KG. Its color is reddish-brown. 

Rafflesia arnoldii was first found by Louis Auguste Deschamps was a famous explorer of Franch. He was a member of a French scientific expedition to Asia and the Pacific. He found it in 1797 when he was expenditing in Java. 

R. arnoldii is very rare and fairly hard to locate. It is especially difficult to locate the flower in forests, as the buds take many months to develop and the flower lasts for just a few days. The flowers are uni-sexual and thus proximity of male and female flowers is vital for successful pollination. These factors make successful pollination a rare event. It can only be seen when it is ready to reproduce. a tiny bud forms outside the root or stem of its host and develops over a period of a year. It looks like a cabbage when the host devoloping. The stigma or stamen are attached to a spiked disk inside the flower. The fruit produced are round lots filled with smooth flesh including many thousands of hard-coated seeds that are eaten and spread by treeshrews. Some environmentalists are developing ways to recreate the species' environment in an effort to stimulate their recovery. This has proved unsuccessful so far. Steps are also being taken to conserve the forests of Sumatra and Borneo.
