Its name comes from Greek and literally means "stomach", for the characteristic shape of the flower, swollen at the base and narrower at the top, which makes it look like a sack. It is a genus rather similar to Aloe (with which, in fact, it is often hybridized), constituted by long and flat fleshy rosette-shaped or, sometimes, forked leaves. The leaves usually have a silky texture, but there are rather refined species, in which the typical dark green color is interrupted by three-dimensional streaks or whitish warty dots. Commonly known as "ox tongue" or "lawyer's tongue", because of the lingual shape of its foliage, it can be cultivated in a very simple way and requires very little attention. It is a perfect plant to decorate working environments, as well as for beginners with little experience!
