Koltua

Koltua is a genus of trees in the family Sapindaceae, commonly known as the soapberry family. These trees are native to the Neotropics, found in parts of South America. Koltua species are typically characterized by their compound leaves, small flowers, and often fleshy fruits. The exact classification and number of species within the genus can vary depending on the taxonomic authority, with some sources recognizing a few distinct species while others may lump them into broader groups.

The fruits of some Koltua species are of interest due to their potential uses. Similar to other members of the Sapindaceae family, such as the soapberry itself (Sapindus spp.) or lychee (Litchi chinensis), the fruits may contain saponins, which are natural detergents. Historically and in some traditional practices, these saponins have been utilized for their cleansing properties. However, the economic or widespread cultivation of Koltua for these uses is not common. Research into the specific phytochemical properties and potential applications of Koltua species is ongoing, contributing to a better understanding of this genus's biodiversity and ecological role within its native habitats.
