Just this past night, wechat IOS released version 7.0. When it first ran after the update, the opening screen turned into a flower. So you know what this flower is? What's the special moral?
New wechat boot screen.
This is a Cosmos bipinnatus, also known as big Persian chrysanthemum. Although the name carries "Persia", it is actually an annual herbaceous Compositae plant originated from the Mexican plateau. As an important ornamental plant, it is widely cultivated all over the world.
Big change of boot screen
The biggest change this time should be the change of the boot screen. The lonely figure on the dark blue earth that we are very familiar with has disappeared. What will come to our eyes is the simple and quiet flowers. This is in line with wechat's low-key and simple style. Let's enjoy it:
Zhang Xiaolong explained the profound meaning: 'when you don't see the flower, it will be quiet with your heart; when you see the flower, the color of the flower will be clear. 'it looks very artistic and beautiful.
The scientific name of Qiuying is Cosmos bipinnatus. The species addition word is very simple and direct, which means "bipinnate". It describes the bipinnate compound leaves of this plant. The generic name 'cosmos' is much bigger. If you are as like as two peas, you will find it spelled exactly the same as the word "cosmos" in English. Does wechat choose Qiuying as the boot screen to echo the previous version of the earth satellite image in secret?
We don't know, but in fact, both of them come from the word '& kappa; &; & sigma; & mu; & Omicron; & sigma f; (Kosmos)' in ancient Greek. Kosmos originally meant 'order, orderly arrangement'. It is believed that Pythagoras first used the word to refer to the universe. Of course, what he wanted to say was' the sky full of constellations'. Although cosmos was used to refer to the universe as early as the 13th century in English, it was really popular in 1848, when Alexander von Humboldt's Cosmos, a book describing the natural geography of the earth, was translated into English.
The name of Qiuying comes before 'cosmos', which means the popularity of the universe in English. After Columbus discovered the new world, the Mexican plant, like corn and other South American crops, began to drift across the sea and spread around the world. Of course, Qiuying was just a wild flower at that time, so it was not as important as food crops. Until the end of the 18th century, Europe officially introduced this kind of plant.
Its debut was at the Madrid botanical garden in Spain, which was named by its director, Antonio Jos & eacute; cavanilles. At that time, the binomial nomenclature of Linnaeus was not very popular. Cavanilles was one of the first crabs in Spain. The reason why we use this generic name is that the 'petals' (or rather a round of ligulate flowers) of Qiuying are arranged relatively regularly in Compositae, taking the original meaning of the word' Kosmos'.
Although they are afraid of Yin, cold and heat, they are very easy to feed because of their strong fecundity. In temperate areas, there are a lot of free life. Its beauty determines that it will become a popular horticultural flower: on the one hand, it is widely used in flower beds and flower paths, as long as the environment is suitable, it will flourish and even form a large area of 'flower sea'; on the other hand, it has also been carefully selected and bred a series of ornamental varieties with petal color changes, petal shape changes and even double petals.
Sometimes, Qiuying will be called "gesanghua" -- representing the "happy flower" of the Qinghai Tibet Plateau. But in fact, apart from having eight petals like the legend, Qiuying has little to do with the Qinghai Tibet Plateau -- not only is it not native to the Qinghai Tibet Plateau, but after the introduction, it is not even the dominant species in the plateau environment. I think this kind of attachment is a little too far fetched.
