Gramineae. Poaceae, also known as Poaceae, is divided into more than 620 genera and at least 10,000 species. There are more than 190 genera and about 1,200 species in China.
About 20% of the Earth's land is covered with grasses, and grasses contain a large number of plants, including a variety of plants commonly known as so-and-so grasses, but it must be pointed out that not all grasses are grasses. Similarly, not all grasses are low grasses, such as bamboo.
It can also be as high as more than ten meters, and it can be connected into a forest.
Plants in the grass family generally have hollow stems with solid knots at intervals. The leaf is composed of two parts: the leaf and the leaf sheath. The leaves come out of the knot in turn, and the leaves of the same knot are born in a plane with parallel veins.
Each leaf is divided into three parts, the lower part wraps around the stem, and the upper part is independent, with a thin film or a ring of fine hairs in the middle of the two. The flowers are small, have no petals, and are pollinated by the wind. The fruit is a fruit of the eye.
Poaceae are widely distributed on the earth, from tropical to cold and alpine regions, from acidic to alkaline soils, and they occur in all vegetation types and are suitable for all ecological environments except the ocean. Common grasses include wheat, corn, rice, sorghum and other food crops.
Tall fescue, sheared grass, early maturing grass and other lawn plants, oats, barnyard grass, white grass.
and dog tail grass.
and other weeds, as well as all varieties of bamboo. One of the Antarctic hair grass species is even found in Antarctica.
Two other meadow species have also been introduced to Antarctica.
Poaceous plants have many uses. Almost all grains, except buckwheat, are grasses, such as wheat, rice, corn, barley, sorghum, etc. Pigs, cows, horses, sheep and other domestic animals also eat grass.
Bamboo can be seen everywhere in daily life, bamboo plant vegetative organ specialization, stalk lignification, sexual reproduction degradation, bamboo stalk is the material for construction, civil engineering, transportation, but also craft supplies, papermaking raw materials and weaving, etc., plant body woody or herbaceous plants.
The root system is mostly fibrous roots. Wild grasses in nature are not only food for animals, but also produce large amounts of oxygen to prevent soil erosion.

Poaceae is the fourth largest family in the plant kingdom (after Asteraceae, Orchidaceae and Fabaceae) and second only to Orchidaceae (runner-up) in the class of monocots. There are more than 10,000 species of grasses and more than 620 genera. There are more than 1,200 species and 190 genera of grasses in China.
There are many kinds of grasses, such as wheat, rice, barley, rye, sorghum, reed, bamboo, thatch, dogtail, corn and other plants.

There are all varieties of grass (including bamboo, gold-inlaid bamboo, light bamboo, Buddha's belly bamboo, phoenix bamboo, etc.), lawn plants (tall fescue, early maturing grass, etc.), food crops (rice, wheat, sorghum, corn, etc.).

Gramineae. Plants include: corn, wheat, tall fescue, shearsEarly maturing grass, rice, sorghum, etc.
There are many grasses, and the common grasses are corn, wheat, tall fescue, shears, early maturing grass, rice, sorghum, oats, barnyard grass, white grass, and dog's tail grass.
rye and sugar cane, among others. Poaceae are generally annual or perennial plants, belonging to shrubs or trees.
class, with rhizomes or stolons.
And the seedlings and flower stems are mixed, they all grow upright, and the leaves are generally solitary on the nodes. Poaceous plants are well adapted to the environment and are a very common plant that is cultivated in many places.
Poaceae
Poaceae are monocots, and grasses include most of the grasses on earth, but it does not mean that all grasses are grasses, nor do they mean that all grasses are low grasses, such as bamboo.
It's also a gramaceae, and it grows very tall. Poaceae is a family of monocots and grasses.
The leaves of grasses are oblong, oval, ovate, lanceolate, etc., sessile, and can be curly when not or dry, with a significant midrib. The inflorescence of the genus Grass is a conical inflorescence of spikelets, spikes or racemes, solitary or apical, with small and inconspicuous flowers. The fruits of grasses are mostly small pelets, with thin skins that cling to the seeds, and few nuts and berries.

Pomineae include wheat, corn, rice, sorghum and other food crops, tall fescue, shearweed, early maturing grass and other lawn plants, oats, barnyard grass, white grass, and dog's tail grass and other weeds, as well as all varieties of bamboo, there are more than 10,000 species, and there are large areas of gramineous plants growing in the world.
Varieties of grasses.
Poaceae is also known as the early maturing grass family, there are more than 620 genera, a total of more than 10,000 species, so what are the grasses, including wheat, corn, rice, sorghum and other food crops, tall fescue, shears, early grass and other lawn plants, oats, barnyard grass, white grass, and dog tail grass and other weeds, as well as all varieties of bamboo.
Poaceae contain many food crops, such as wheat, corn, rice, sorghum and other food crops, 20% of the earth is covered with grass, while grasses contain a large number of plants, but not all lower grasses, such as bamboo, are special examples.
The earth's grasses are extremely widely distributed, from tropical to cold regions, from acidic soils to alkaline soils, and they occur in all vegetation types and are suitable for various ecological environments except the ocean.
Bamboo plant vegetative organ specialization, stalk lignification, sexual reproduction degradation, bamboo stalk is the material for construction, civil engineering, transportation, but also craft supplies, papermaking raw materials and weaving, etc., the root system of woody or herbaceous plants of the plant body is mostly fibrous roots.

Poaceae is the fifth largest family of angiosperms, second only to the orchid family in the monocot class, and is the second largest family of monocots, with nearly 12,000 species. There are many common grasses, such as: corn, wheat, rice, barley, oats, bamboo, reeds, dogtails, thatch and other plants belong to the family of grasses.
The leaf veins of grasses are parallel veins, and the leaf edges are jagged, relatively sharp, and easy to scratch. The seeds have a cotyledon and an endosperm. The root system is fibrous roots. There is no cambium in the stem.
The economic use of grasses is very high, for example, all kinds of snacks and food crops we eat daily are from wheat or rice, bamboo can blow bamboo leaf whistles, make textile fibers, ornamental, and make bamboo leaf tea.
