What is the smallest leaf in the world?

There is no smallest leaf, there is the largest:

In the Amazon palm of South America, a leaf with a stalk is a meter long. The tropical long-leaf coconut, a leaf is 27 meters long and stands up to seven stories high. This is the longest known leaf;

The leaves of the plant with the largest leaves, the royal lotus, can be said to be the largest among the aquatic flowering plants. However, it is not yet the largest leaf in the world. Among the terrestrial plants, there are also larger leaves than the royal lotus, which is the large root of the Naira grass that grows in the forests of Chile.

One of its leaves can cover three people riding side by side, even people and horses.

The largest leaf in the world is the Amazon palm.

The Amazon palm in South America is recognized as the world's champion in long-leaved leaves, with leaves up to a metre long and a height equivalent to seven floors. Palm is an evergreen tree of the palm family, up to 7 meters tall; Dry cylindrical, leaves nearly rounded, petioles with fine round teeth on both sides, inflorescences stout, dioecious.

Presentation of the Amazon Palm

Flowers yellow-green, ovate-shaped; The fruit is broad, kidney-shaped, has an umbilicus, changes from yellow to light blue when ripe, has white powder, and the seed endosperm is keratin. The flowering period is April, and the fruiting period is December. It is usually only cultivated on all sides, and rarely wild in open forests, with an altitude of about 2,000 meters; Although it can be cultivated in the north of the Yangtze River, the stems must be wrapped in grass to protect against the cold in winter.

Vertically distributed at an altitude of 300-1500 meters above sea level, in the southwest up to 2700 meters. Palm likes a warm and humid climate, is extremely cold-tolerant, more shade-tolerant, and the finished product is extremely drought-tolerant, but it cannot withstand too much temperature difference between day and night. Palm is the most widely distributed and highest latitude of palm species in China.

It likes warm and humid climates and loves light.

It is extremely cold tolerant and slightly shade tolerant. It is suitable for well-drained, moist and fertile neutral, calcareous or slightly acidic soils, and is resistant to light salinity, as well as some drought and moisture. Strong resistance to air pollution.

It is easy to fall by wind and grows slowly. There are many varieties of Amazon palm, such as horsetail palm, plate palm, hairy palm, mountain palm and so on.

Wang Lian: The world's largest leaf, with a diameter of more than 3 meters, a smooth leaf surface and a rolled leaf margin, like a large emerald green jade plate floating on the water; Because its leaf veins are different from the leaf vein structure of ordinary plants, they are rib-shaped, like umbrella frames, so they have a great floating jujube driving force, and can withstand up to sixty or seventy kilograms of objects without sinking.

The world's longest foliage plant is the long-leaved coconut leaf, the Amazon palm in South America, where a leaf with a stalk is a meter long. A leaf is 27 meters long, and it is 7 stories tall when erected, which is the longest leaf known so far.

Summary. Hello, bamboo, native to South Africa, is the smallest plant in the world with leaves. Wenzhu is not actually bamboo, but a perennial vine.

Because the branches and leaves are slender and knotty, like bamboo, it is called "Wenzhu". The branches are numerous and thin, and what we think of as the leaves are actually the stems and branches, which have degenerated into white scales and hide at the base of the leaf-like branches. To see the bamboo leaves, you have to ask a magnifying glass to help.

Hello, Acacia tree, also known as night tree, lantana, velvet tree, is a deciduous tree of the Mimosa family and Acacia. The leaves of the acacia tree are small and opposite. The leaves of mimosas are also opposite, and the seedlings of the acacia tree should be very similar to mimosas, because in Shi Tiesheng's essay "The Acacia Tree", his mother mistook the acacia tree seedlings for mimosas and planted them in the yard.

Not only that, but I also saw information that the leaves of the acacia tree close at night, as if a husband and wife are reunited, and it is a famous acacia tree. I didn't observe the leaves of the acacia tree at night, so I didn't know about it, but even if the leaves of the acacia tree could be closed like the mimosa, they would not be considered close relatives, because mimosa is grass and acacia is arbor.

The largest leaf in the royal lotus is the famous plant in the Amazon River in South America, the royal lotus leaf. It and the common lotus flower are the brothers of the water lily family. Generally, the diameter of lotus leaves is 60-70 cm, but the diameter of lotus leaves is 200-300 cm, and the maximum is 400 cm.

The lotus leaf floats on the surface of the water, like a large round basin. Generally, the leaves of lotus leaves can only hold one frog, and the leaves of Wang lotus leaves can hold a child of thirty or forty pounds. The royal lotus is a perennial aquatic plant, which, unlike the lotus, has a well-developed root system, but does not have a taproot and lotus root.

Each royal lotus leaf can grow 20-30 extra-large leaves. In addition, the fruit of the royal lotus is round, and there are two or three hundred seeds in it, each of which is the size of a corn kernel, contains a lot of starch, and is edible. Locals call its staple food "water corn".

1.The leaves of the royal lotus have many air chambers that allow the leaves to float on the surface of the water in a balanced manner.

2.The royal lotus is a very famous aquatic ornamental plant in the tropics and the largest leafy aquatic plant in the world, with a diameter of more than 3 meters. The veins of the leaves are different from those of ordinary plants, which are prismatic and can bear up to sixty or seventy kilograms of weight.

3.The reason why Wang Lian has such a supporting force is mainly because the veins on the back of Wang Lian's leaves are relatively thick, and the average force will not break easily.

The giant leaves of the royal lotus are not only eye-catching, but its weight-bearing capacity is even more amazing. The large blade can bear a weight of 70 kg because it has many large cavities in the blades and veins, and the cavities are filled with gas, which makes the blades float on the surface of the water. There are thick veins on the back of the leaves, plate-like protrusions, criss-crossing to form a square lattice with a height of more than 10 cm, which is conducive to maintaining the development of the leaves and increasing the drainage and load of the leaves.

Hello! There is the Amazon palm in South America, and a leaf with a stalk is a meter long; The tropical long-leaved coconut, a leaf is 27 meters long and seven stories tall when erected, which is the longest leaf known to date; The leaves of the royal lotus are the largest among the aquatic flowering plants; The big root nera grass that grows in the Chilean forest, its one leaf, can cover three people riding side by side, even people and horses, look!

The largest foliage in the world is the Amazon palm leaf in South America.

The Amazon palm is recognized as the world's champion in long-leaved leaves, with its leaves reaching a height of up to a metre and being erected up to a height equivalent to seven floors.

The Amazon is rich in precipitation and has high temperatures throughout the year. As a result, it is a gathering place for tropical plants. Palm trees are a tropical plant, but it is a natural credit for being able to grow such long leaves, and the palm trees here are generally taller, forming a unique landscape of the rainforest.

There are many varieties of palm trees in the Amazon plain, some of which grow in rainy places and some of which grow in rocks. Palm trees growing in rocks are very resistant to drought and can survive even in the absence of water. There is also a type of palm tree that grows in water, although this type of palm tree is not very common.

Introduction of Palm Trees:

Palm (scientific name: Trachycarpus fortunei (hook.)) is an evergreen tree of the palm family; The trunk is cylindrical, the leaves are nearly rounded, the petioles are finely toothed on both sides, the inflorescences are stout, dioecious.

Flowers yellow-green, ovate-shaped; The fruit is broad, kidney-shaped, has an umbilicus, changes from yellow to light blue when ripe, has white powder, and the seed endosperm is keratin.

The palm tree has commercial value, its leaves can be used to make palm beds, and the trunk can also be used as furniture. Palm trees also have a high nutritional value and are rich in minerals. Locals like to use palm fruit to squeeze oil and eat it.

Lotus leaves.

The largest leaves are the famous plant of the Amazon rivers in South America, the royal lotus leaves. It is the same as the lotus flower in general, and is a brother in the family of water lilies. Generally, the diameter of lotus leaves is 60-70 cm, but the diameter of the king lotus leaves reaches 200-300 cm, and the maximum is 400 cm.

The royal lotus leaves float on the surface of the water, as if they were a large round basin. Generally, the leaves of lotus leaves can only support a frog, but Wang Lianye can support a child of thirty or forty pounds. Wang Lian is a perennial rooting aquatic plant, which is different from Lian in the following ways:

The root system is well developed, but there is no taproot, no lotus root, and each king lotus leaf can grow 20 30 very large leaves. In addition, the fruit of the royal lotus is round and spherical, and there are two or three hundred seeds in it, each of which is as big as a corn kernel and contains a lot of starch, which is edible. Locals use it as a staple food, giving it the nickname "corn in the water".

Wang Lian's leaves can stand a child.

The leaves of the royal lotus are the largest leaves in the world.
