One of the most ancient groups of fern-like plants are lycopods, which are also called lycopods. They are often evergreen, perennial plants. But despite this, such herbs can be found on the territory of almost the entire globe, since they are unpretentious to any environmental factors and can grow almost anywhere.

Types of lymphoid plants

Several groups of plants belong to lycopods, which will be discussed below.

Half ears - they can grow under water, which is typical only for this species of this category, or they can be partially submerged in it. In appearance, they most of all resemble cereals, although they do not belong to them in any way.

Selaginella - there are more than 600 species in total, which mainly grow in the tropics. More such plants are similar to moss, due to small leaves. Selaginella are also found, which give exclusively vertical shoots, but at the same time are creeping.

Plaunas are directly the most common species, possessing all the characteristic features of lycopods. This is expressed both in external signs and in places of growth. It is these herbs that are considered the main representatives of this class.

It should also be noted that lymphoids are plants that are spore, that is, they reproduce primarily through spores and belong to the highest. Accordingly, they do not form seeds or fruits, which complicates the process of their artificial cultivation. All species of lycopods are generally similar to each other, and it is quite easy to distinguish them from other plants, especially knowing the general picture of the appearance of this class.

The appearance of lyciform plants

The appearance of lycopods mainly depends on their place of growth and a specific group. As mentioned above, there are several of them, and such plants can be found almost anywhere in the world.

In any case, considering the external characteristics, it is necessary to start with the largest group - the lymphoids. They are most similar to mosses, they have small and simple leaves. Scaly or needle-shaped lyes are sometimes also found, so this group is really very extensive and includes many different herbs.

They are characterized by erect stems, sometimes creeping or rising. Plauns can "climb" trees thanks to their aerial roots. Also, in a few species, the presence of medium-sized branches is noted, which usually contain from one to four small leaves. Such branches are called brood buds, and they are the only organs of vegetative reproduction in lycopods, since they are separated from the stem and, falling on the ground, can grow.

This is followed by semi-headphones. These are herbaceous plants, small in size, with basal leaves. In fact, all half ears are very similar to each other, and at the same time resemble cereals. Leaves are green or dark green in color, long, with slight roughness. If the half-mushroom grows not in water, but on land (this happens only in well-humid places, that is, near water), then only in thickets.

Some plants are white at the very base of the root, which then sharply turns green.

Selaginella are distinguished by a thick stem covered with small, flat leaves. They are also creeping, and in this case they give vertical shoots that branch and because of this they become like frond ferns. Important! If selaginella lacks water, then they fall into a state similar to hibernation, and at the same time curl up in a ball.

In general, all lycopods in appearance can be described as follows: evergreens, with medium-sized, simple leaves, small in size. They have uplifting or creeping stems, which is why they are especially reminiscent of mosses, especially given the fact that lycopods can often be found in trees.

Some features of a particular group do not particularly change the overall picture, so when searching for lycopods, one should focus on these parameters. In addition, it is important to take into account that, unlike mosses, almost all moss have a stem.

Where do they grow?

Lycopods can be found both in the tropics and on the territory of our homeland. Specifically in Russia, various species of lyre grow most often in forests, most often in conifers, much less often in mixed ones. They grow in small thickets, but sometimes separately from each other. More specifically, in which cities lycopods are common, then it is necessary first of all to highlight:

  • Ural, especially its southern part
  • Altai region
  • Yaroslavl
  • Moscow
  • Vladimir
  • Ivanovsk

These are not all cities, and in general, you need to focus on the northern half of the European part, where you can often find ploons. Important! Half-ears are found only in the purest water, and nothing else. This class of plants never grows in polluted waters, but it can often be found in crystal lakes.

In addition, lycopods grow in the territories of Atlantic and Central Europe, North America and Scandinavia. Specifically, Selaginella, this class prefers warmer climates, and because of this, it is most often found in the tropics.

To all of the above, it must be added that absolutely all species of composites are listed in the Red Book of Russia, since, according to scientists, they are on the verge of extinction. Especially at the moment, the half-ears class suffers.

So, lycopods are plants that are very common. They are controversial and are part of the higher department. In terms of external characteristics, they most of all resemble mosses.
