Sapindinae

Sapindinae is a subtribe of flowering plants in the soapberry family, Sapindaceae. This group is characterized by certain floral and fruit structures that distinguish it from other subtribes within Sapindaceae. The species within Sapindinae are predominantly found in tropical and subtropical regions across the globe.

The taxonomy of Sapindinae has been a subject of ongoing research, with molecular studies contributing to a better understanding of its phylogenetic relationships. While traditionally defined by morphological features, recent classifications incorporate genetic data to refine its boundaries and relationships with closely related genera.

Notable genera often placed within Sapindinae include Sapindus, known for its soap-like fruits, and Litchi, which includes the popular lychee fruit. Other genera in this subtribe are diverse in their habit, ranging from trees and shrubs to vines. The fruits of Sapindinae members exhibit a variety of forms, often being fleshy or capsular, and are dispersed by various mechanisms including animals. Their ecological roles vary, with some species contributing to forest canopy structure or providing food resources for wildlife. The economic importance of Sapindinae is significant, primarily due to the cultivation of species like Litchi chinensis for its edible fruit.
