Callisia is a genus of plants belonging tothe Commelina family (Commelinaceae). The botanical name of the genus is derived from the Greek word kallos for 'beauty'.

description

The species of the genus Callisia are perennial , rarely annual or short-lived herbaceous plants with succulent leaves .

The inflorescence is different. It usually consists of coils that are united in pairs. There are no noticeable bracts. The sessile or stalked flowers are usually actinomorphic and hermaphroditic. Their three, very rarely two, sepals are occasionally hyaline . The three, very rarely two, not fused petals are usually white or pink. The six stamens are all the same or almost all the same or reduced to three or one. The stamens are usually hairless , but sometimes bearded. The anthers are movable and their connective mostly wide. The ovary is three-sided and rarely two-sided. There are two ovules in each compartment . Very rarely is there just one. The scar is usually brush-shaped or tiny head-shaped.

The fruits are small capsule fruits . They contain seeds with a point-like hilum .

Systematics and distribution

The genus Callisia is common in the southeastern United States , Mexico, and tropical America.

The first description by Pehr Löfling was published in 1758. The genus Callisia includes the following species:

To this extent the genus Callisia is not monophyletic .
