The document summarizes key information about the pea family (Leguminosae or Fabaceae). It belongs to the dicotyledon class and includes 482 genera and over 12,000 species worldwide. In India and the Andhra Pradesh/Telangana regions, there are around 100 genera and over 750 species. The family includes herbs, shrubs, trees, twiners and tendril climbers. Plants have a taproot system with root nodules, alternate compound leaves, and papilionaceous flowers. Economically important plants provide pulses, vegetables, oils, fodder, fibers and have medicinal uses.
