After talking about what a cactus is, we will move forward to know and recognize these plants more precisely.

How are the forms of cacti?

Today we are going to speak in a simple way what are the different forms that we can observe among cacti. Introduction:
The / i> is what basically forms the body of the plant, its thickening is a special development of the cacti as well as other types of plants and is green because it does photosynthesis.

We can observe three main forms of stem, of the cactus:
* Segmented: flattened stems in the form of racket (as in the genus opuntia) also called cladodes, articles among others. cylindrical (with or without branching).
If branching from the base is called columnar-basitone, if instead branching through the middle of the stem is columnar-mesotone and if instead does at the tip of the stem, columnar-acrotono

* Globally: stems almost spherical, or with barrel size (such as the Mammillarias, Echinopsis etc) * * Epiphytes-branching: stems growing in trees, elongated and branched pendants

Creeps: usually cylindrical stems that instead of being completely erect fall and develop on the ground or sometimes hang from rocks, slopes and other reliefs Finally we see some example images so that we can classify and recognize them easily in the forms that we just studied

In a segmented / articulated way

The cactus of the genus Opuntia for example have this characteristic form

Columnar form

and Trichocereus are an example of this arrangement


Many genera of cactus have this form, for example Mammillarias, Echinopsis, Lobivias and Parodies

branched (epiphyte)


The stem is generally cylindrical as in the columns but its arrangement makes the difference as far as the concept of form is concerned. Some Cleistocactus, Echinopsis, for example have this provision
