In botany, as in any other science, a systematic approach to the subjects of research is important. Classify signs and properties, identify patterns and exceptions - all this is necessary for the effective study of plants. In botany, this task is facing taxonomy. It is she who identifies instances that have much in common. Such plants are united by scientists in special groups called species.

Species of plants of the genus Lily

Visual examples of plant species we can observe by examining such a flower as a lily. It belongs to perennial herbs, grows from a bulb, has fleshy leaves growing from below and flowers of white, yellow, orange colors. The genus Lily is subdivided into more than 100 species, the bulk of which in the natural environment grows in Asia and Europe. Examples of plant species we will now consider.

Everyone knows the snow-white (or silver) beauty, whose homeland is Greece. There is the so-called Lilia Anhui, there is a bolander, calloused, etc. Despite the different, sometimes very exotic names, these flowers are similar in structure and growth conditions. Their stem is a continuation of the bulbous bottom, and the leaves grow in a spiral, as it were, without any cuttings (with the exception of a few specimens). Such examples of plant species just speak of a wide variety of wildlife forms. But the formation of onion “baby” from the main, maternal, in almost all lilies is the same. It originates in the corner of the lowest leaf and matures in a year. If the plant is grown from seeds, then it takes 5 to 7 years to wait for its maturation and flowering.

Onion lily (bulbous)

Consider some examples of plant species lily - for example, Lily bulbous. In length, these flowers usually grow more than a meter. The leaves are long, narrow, sharp. Color - dark green. The flowers are bright, saturated colors. On the stem they can be from three to five pieces. Cuttings are short. The petals are large, within 5 cm. Their inner side is velvety in appearance and to the touch, covered with specks of a brownish tint. Other types of plants, examples of which we consider, are distinguished by the fact that they do not form bulbs in the axils of their leaves, although they are also called onion-bearing ones. This, for example, the so-called Lily Bulbiferum, whose homeland is Italy and France.

Lily family

As we have already found out, the type of lily lilies is very diverse and many-sided. But due to the presence of common characteristics, plants of this species are combined into one genus. And even if there is some similarity between the clans, they also create a “coalition” of a higher rank - the family. For example, the lilies we have already examined have “neighbors”: hyacinths and tulips. On the basis of this botany, general species of the liliaceae plant family, Liliaceae, are considered. Families come together in orders — the next step in the hierarchy. And classes are already made up of them.
