The Mamoncillo, also known as Spanish Lime or Genip, is a tropical fruit tree known for its small, green, round fruits that grow in clusters. The fruits have a tough outer skin, which is easily peeled to reveal a juicy, translucent orange or pinkish flesh with a sweet and tangy flavor. The taste is often described as a mix of lime and lychee. Mamoncillo is commonly eaten fresh or used to make beverages and desserts in tropical regions.

The tree itself is tall and fast-growing, with a broad, spreading canopy of glossy, dark green leaves. Mamoncillo thrives in warm, tropical climates and is drought-tolerant once established. In addition to its fruits, the tree is sometimes planted for ornamental purposes due to its attractive foliage.
