Arthrocereus is a genus of cactus, native to southeast and west-central Brazil. [1]
The relatively small, bushy, erect or prostrate species of the genus Arthrocereus are branched or unbranched. The articulated, cylindrical shoots have 10 to 18 low and narrow ribs on which small areoles sit from which many thin thorns emerge. The elongated, bell-shaped, wide-opening flowers appear near the shoot tip and open at night. The flower cup and the flower tube are covered with wool, hair-like thorns and a few pointed scales.
The spherical to obversely pear-shaped fruits are green and have white flesh. They are thin-walled, non-tearing, and have scales and hair-like spines. The slanting egg-shaped seeds are black. [2]

The Typhaceae are a family of flowering plants, sometimes called the cattail family. The botanical name for the family has been recognized by most taxonomists.
Utricularia, commonly and collectively called the bladderworts, is a genus of carnivorous plants consisting of approximately 233 species. They occur in fresh water and wet soil as terrestrial or aquatic species across every continent except Antarctica. Utricularia are cultivated for their flowers, which are often compared with those of snapdragons and orchids, especially amongst carnivorous plant enthusiasts.
Gymnocalycium, commonly called chin cactus, is a genus of about 70 South American species of cactus. The genus name Gymnocalycium refers to the flower buds bearing no hair or spines. In a 2023 classification of the tribe Cereeae, it was placed as the only genus in the subtribe Gymnocalyciinae, having formerly been placed in the subtribe Rebutiinae.
Pediocactus is a genus of cacti native to the Western United States. The genus comprises between 6 and 11 species, depending upon the authority.

It is assigned to the family Strasburgeriaceae.
