Added: National Treasure gymnosperm - Metasequoia.
It belongs to the fir family, and its Latin scientific name is metasequoia glyptostnobcides.
Large deciduous tree, 35-42 meters high, diameter at breast height. The base of the trunk is swollen, and the bark is grayish-brown, split into long strips. The large branches stretch diagonally upward, and the 1-year-old branches are light gray.
The winter buds have short white scars above or on the sides. Leaves linear, soft, pinnate on lateral branches, monoecious, cones drooping, ripe in the year, nearly spherical or elliptic-spherical, seeds flattened, obovate, winged around.
The climate is warm and humid, with cool summers and snow but not cold winters. The soil is acidic mountain yellow soil, purple soil or alluvial soil, pH value. It is mostly found in valleys or foothills at an altitude of 800 to 1200 m above sea level, with gentle, deep, moist or slightly waterlogged areas.
It is a light-loving tree species, with a well-developed root system, and the speed of growth is often governed by soil moisture, and it grows slowly in places with long-term water accumulation and poor drainage, and the base of the trunk is usually swollen or has longitudinal ridges. The flowering period is late February, and the cones ripen from late October to November.

Metasequoia metasequoia is a large deciduous tree of the fir family; Ginkgo biloba is a deciduous tree of the family Ginkgo biloba; Dove tree is a deciduous tree belonging to the family of blue-fruited trees.
Metasequoia is gymnosperms, ginkgo biloba is gymnosperms, and dove trees are angiosperms.
Ginkgo biloba has a straight trunk, a broadly ovate crown, and a light grayish-brown bark with longitudinal lobes. The seeds are drupe-shaped, oval or spherical, and the outer skin is fleshy yellow with a white powder.
Metasequoia is native to China, is an ancient relict plant and living fossil, one of the national key protected trees, metasequoia likes sunlight, more cold-tolerant, not shade-tolerant.
Dove trees, also known as pigeon trees, survive only in small numbers in some remote mountainous areas in the southwest (between 1,600 and 2,200 meters above sea level). Annually.
It blooms in April and May, and the flower color is pure white.

1. Ginkgo biloba.
The ginkgo tree is also known as the white fruit tree, and in ancient times, it was also known as the duck's foot tree or the gongsun tree. More than 270 million years ago, the ancestors of ginkgo biloba began to appear, and it was still a higher plant compared to the ferns that were all over the world at that time. More than 170 million years ago, ginkgo biloba has been spread all over the world like the dinosaurs that dominated the world at that time, and later, most of the ginkgo biloba became extinct like dinosaurs, and only a little bit was preserved in some parts of our country, and it has been passed down to the present and become a rare treasure.
Ginkgo trees are divided into male and female, male ginkgo trees, only male flowers, female ginkgo trees, only female flowers, fertilization will produce round fruits, generally known as ginkgo seeds.
Ginkgo biloba is the only surviving species of gymnosperms Ginkgo biloba. Now wild ginkgo biloba can still be seen in the area of Tianmu Mountain in Zhejiang. Therefore, ginkgo biloba has"Living fossils", in plants"Pandas"called.
Ginkgo biloba is one of the most precious tree species in the world, and together with cedar, araucaria and golden pine, it is known as the world's four major garden trees.
The ginkgo tree not only has a high ornamental value for its handsome and upright leaves, but also has strong adaptability, great medicinal effects, and considerable economic value.
2. Metasequoia. Metasequoia is a deciduous and coniferous tree. It is one of the rare and precious plants in ancient times, and is a first-class protected plant in China.
Metasequoia, a precious relict plant that has experienced the catastrophe of the Quaternary glaciation, grows rapidly, reaching more than 10 meters in about 10 years, and can become mature in 2o years. The material is light and soft, the texture is straight, the structure is fine, it is a good material for shipbuilding, construction, bridges, agricultural tools and furniture, and a good raw material for the paper industry.
Metasequoia is not only a precious "living fossil", but also it has a strong vitality and a wide range of adaptability, grows rapidly, is an excellent greening tree species, not only has been widely cultivated in various parts of our country, many countries in the world are also vying to introduce cultivation, so that this precious tree grows endlessly in the world.
3. Dove tree. Dove tree, also known as water pear, pigeon tree. It belongs to the family of bluefruit tree, a national first-class key protected plant, and is a monotypic plant that is a special product of China. It is about 10 to 20 meters high, tall and straight, is a very beautiful deciduous tree, and is a famous ornamental tree species in the world. Annually.
In April and May, the dove tree blooms and blooms, and there are two white bracts of different sizes under its head-shaped inflorescence, which are oblong or oval, six to fifteen centimeters long and three to eight centimeters wide, such as white silk cut, beautiful and peculiar, like a white dove stretching its wings; And its head-like inflorescence resembles the head of a white pigeon, so the dove tree has the reputation of "Chinese pigeon tree". The wooden structure of the dove tree is fine, not easy to deform, easy to cut, and is a good material for wood carving technology. More importantly, it has important scientific value for the study of paleoflora and phylogeny.
The dove tree was discovered in China in 1869. Due to the excavation of wild seedlings and the destruction of forests, the number is currently small, and the distribution range is shrinking, and there is a risk of being replaced by other broad-leaved tree species.
-
Dove tree is an angiosperm plant. Metasequoia ginkgo biloba is a gymnosperm.
-
Angiosperms, with the differentiation of rhizomes, leaves, fruits, and seeds.
It is a leafy vegetable of the Brassica genus of the cruciferous family.
Phylum: Seed plant phylum: Angiosperm subphylum.
-
It should be angiosperms, gymnosperms have pine family, cypress family, fir family and ginkgo family, generally relatively tall.
-
Angiosperms, which have a differentiation of rhizomes and leaves, and belong to the cruciferous family.
Your ** is beautiful, I saved it, I wish you a happy day.
-
All green flowering plants are angiosperms, and greens are angiosperms.
-
Angiosperms have the differentiation of rhizomes, leaves, fruits, seeds.
So greens are angiosperms.
-
That depends on what kind of dish it is.
Cabbage, coriander, green onions, and the like are angiosperms, but most of them are angiosperms.
-
Angiosperms, everyone agrees, our teacher said, it must be correct, thank you.
-
It's all ah, there are not many gymnosperms now.
Gymnosperms are generally ferns.

Tulips in flower arrangements can live for 1-2 weeks, depending on the quality of the flowers and the method of care. >>>More
Tulips prefer warm and humid winters, cool and dry climates in summer, love light, tolerate semi-shade, and bask in more sun after the leaves are unearthed. The suitable growth temperature is 15 to 20 °C, the bulb can tolerate 35 low temperatures in winter, and 30 leaves wilt in summer. The potting soil should be kept moist during the growing period and avoid stagnant water. >>>More
Liliaceae, a herbaceous bulbous flower of the genus Tulip is a long-day flower, which likes the sun and shelters from the wind, and has a warm and humid climate in winter and cool and dry in summer. It can grow normally above 8, and can generally tolerate -14 low temperatures. It is very cold-tolerant, and if there is thick snow cover in severe cold areas, the bulb can overwinter in the open field, but it is afraid of the heat, if the summer comes early and the summer is very hot, it is difficult for the bulb to survive the summer after dormancy. >>>More
As we know, tulips are hardy and not heat-tolerant, it will go dormant on its own in the hot season, it prefers a warm, cool climate and a leeward environment, and grows better in neutral or slightly acidic soils. A mature tulip bulb contains three generations of bulbs, or three generations of bulbs. The first generation of bulbs is the large bulb, which can be directly differentiated into a complete flower organ, and can bloom in the year after planting, while the second and third generation bulbs are subballs, which are used to breed large bulbs. >>>More
