Acacia: The “background tree” on the African grasslands
Among the arbor species in the African steppe is the acacia, which is the “background tree” where the bark is yellow-green and the branches grow obliquely upward. Acacia is a large family, mainly Acacia, Acacia, and catechu. Acacia trees on African grasslands are mainly members of Acacia and catechu.
Kodak acacia is a common type, its trunk is solid and the foliage is lush. In order to prevent the animal from eating its leaves, a pair of hard thorns grow on each section of the branches. The lower the branches or the sprouting branches, the longer the hard thorns and the shorter the thorns at the top of the tree. In addition to the giraffes, few herbivores can eat the leaves of the high places.
Acacia is a dwarf shrub that is no more than 2 meters high, so many animals can eat its leaves. In addition to the long thorns, it has developed a special strategy – the base of each pair of thorns will expand into a spherical shape, with some hollow pipes and spaces inside, where ants can live or stay inside, if Some animals dare to invade the leaves of the acacia, and the ants will attack and attack.
Fragrant flower tea is also a member of the big family of Acacia. Its branches are full of curved barbs. If you accidentally touch its branches, you can’t help it. Only a thick and thick giraffe can deal with it, not only the leaves, but also the flowers.
Baobab: A “bread” that can be eaten as a snack.
The kuala tree of Malvaceae is also a widely distributed deciduous tree species on African grasslands, often forming a distinctive landscape. Its trunk is very large, and some trees are said to have a life span of thousands of years. The baobab tree has long leaves and flowers in the rainy season, deciduous leaves in the dry season, and mature fruit. The common state is the dry season. When the elephant is far from the water source and thirsty, it will slam the trunk of the baobab tree with its teeth, and cut through the water-transporting tissue to obtain the water in the trunk.
The baobab tree has a large flower size of up to 15 cm in diameter and hundreds of stamens, which are bundled into a bundle; the fruit has a stick-shaped shape and can grow up to 30 cm when mature. In the dry season, although the baobab tree is deciduous, it is easy to see the yellow-brown fruit hanging from the tree. The fruit is chopped up, with white filamentous flesh and lumpy seeds, which are determined to be rich in calcium and vitamin C. The flesh can be eaten raw, tastes sweet and sour, or added with water to make juice, or as an additive to other foods, such as added to milk.
The fruit of the baobab tree can’t be made into bread or staple food, and can only be eaten as a snack. The bread tree of the genus Sankobola is a food that can really fill the stomach because the fruit is rich in starch. The baobabs and bread trees are actually not hit by the gossip.
Thousands of trees: plant giants in the East African Plateau
The East African region is active in the crustal movement, so several mountains stand on it. From the savanna at the foot of the mountain to the rainforest and bitter flowers on the mountainside, the mountain forest dominated by the Lohansson in the east, and the heath shrubs above 3,000 meters, and the land above 3,600 meters is the site of the thousand miles. The tall, arbor-like body forms a sparse “forest” landscape – one of the most fascinating landscapes in the high mountains of East Africa.
The genus Thousands is a member of the Compositae family. There are 11 species, all of which are specialties in the high mountains of East Africa. If they go to the small family, they belong to the Senecio. The senecio that is common in our country is herbaceous or weak vine, and Thousands of trees are the giants in this small family. They often grow into tall trees, and in their harsh mountain environment, they use their burly body to meet the cold wind. .
Shuo Lian: Optimus Prime of the Half Lotus family
In the bitter cold of high altitude, in fact, Qianlimu is not alone, and there is a kind of giant herb accompanying it, that is the Shulian of the platycodon family. There are more than 20 kinds of Shuolian. The common varieties are Daxuan Shulian, Pengtou Shulian, Zhulin Shulian, and Broadleaf Shulian, which are concentrated in East Africa and a few species extend to West Africa. Their common features are: basal leaves densely populated, forming rosette-like leaf clusters, tall stems, rods or long columns, flowers spirally dense on the inflorescence axis, often hundreds of many, large and dense , often cover the flowers. In the mountains of Mount Kilimanjaro, Mount Kenya, Mount Elgon, etc., it is easy to see the statues of Shuolian. They are like a giant pillar of the sky, standing in the forest, on the edge of the bamboo forest, and the heather shrub. In, or born in the meadows and forests.
