Today, the Rosaceae familyspread throughout Europe, South Asia and North America. It includes about one hundred different genera and more than three thousand species. The shades characteristic of the flowers of these plants are most often white, and red, yellow, orange, and pink are also found. Curious fact - despite the fact that the Rosaceae family includes a huge number of the most diverse representatives, among them there is none with flowers of blue color.
Despite the fact that some groups of rosaceous sometimesare classified as separate families, scientists argue that yet all such plants can be characterized as a single family, since the majority of its representatives originated from a single progenitor. Recalling biology, we determine that the class of dicotyledonous plants includes the family Rosaceae. Inflorescence of representatives of this class is found in a variety of variations. They are usually single-sexed and have a five-membered perianth. The leaves are both simple and complex, and have developed stipules.
The classification of the Rosaceae family includes the main four subfamilies:
1. Spiraeous.
2. Pink.
3. Apple tree.
4. Plum.
Of all the existing subfamilies, the mostprimitive spiree are considered. As a rule, these are low shrubs, sometimes even trees, although sometimes there are perennial grasses. Their bright aroma attracts during the flowering period a lot of insects for pollination. Representatives of the subfamily of spirals are often used in gardening. In industry, they are widely used for the production of household chemicals.
Семейство розоцветные включает в себя самое large subfamily - pink. Representatives of this subfamily can be found on the territory of all climatic zones of the world, from the equator to the islands of the Arctic Ocean. Trees among them are absolutely excluded. In agriculture, there are often such species as raspberries, blackberries, strawberries. The overwhelming part of grasses is represented by rhizome perennials.
The most common representatives of the familyapple-trees are various kinds of pears, hawthorn, apple-trees and mountain ash. They are characterized by dense fleshy fruits. Plants of the subfamily apple are similar to the spermine in the choice of places of growth. Both those and others are more often found, as a rule, on the slopes of mountain ranges. White and pink flowers of these plants are widely used in the medical field. Fruits of irgi, hawthorn and mountain ash are quite edible for humans, but more often they eat animals that do not fall asleep for the autumn-winter period.
Representatives of the subfamily plum, as a rule,grow in Asia and in Europe, although you can meet them even in the Andes. In this subfamily, evergreen plants are often found, but mostly deciduous plants prevail, and their flowers are usually collected in a bundle. Among them there are both lovers of the mountain and tropical climate, and those who prefer mossy forests. Trees belonging to the family of plum trees, during flowering, give off a terrific fragrance. He is able to attract not only insects, but people will not remain indifferent.
Despite the fact that today practicallythe family of Rosaceae is widespread, its representatives, as a rule, are most often found in conditions of temperate and subtropical climate. They are widely used in various fields of human activity. They include all kinds of fruit crops: plums, cherry, apple, quince, pear, peach, cherry and many others. Many berry crops also belong to this family, in particular, strawberries, raspberries, strawberries. In addition, the Rosaceae family is famous for its beautiful and fragrant flowers, therefore its representatives are widely used as decorative ornaments in gardening.
