A total of 444 plants are considered. When choosing them, I was guided exclusively by the frequency of their occurrence. Plants that are more or less rare are excluded. The book consists of two parts. The first part is the determinant, the second part is special. In the latter, all plants are grouped by family. Before each large family, its characteristic is given. The name of the plant is followed by its morphological description, then an explanation of the name, biology, applications in medicine, technology, the meaning of the plant from an agricultural point of view, etc.
