Lime trees are hybrids of different types of citron plants. The type of plant species and the genus brings about the different types of lime trees.
There are 4 main types of lime trees which include key limes (Citrus aurantifolia), tahiti lime tree (Citrus latifolia), Thai lime (Citrus hystrix), and Rangpur lime (Citrus × limonia). These varieties are unique in the way they taste, their physical features, and how and where they’re grown.
See the pictures of the different types of lime fruits below.
All limes have a comparable nutritional profile. The only distinguishing factor of the lime tree is its size and shape of the trees. The fruit’s size, shape, color, and rind texture are also the distinguishing features of different types of lime fruits. Flowers can also help classify the different types of lime trees.
