In the Old World there are a number of species of euphorbias and other genera that have thorns. In the new world (Americas) cacti have spines (not thorns) but are succulents.
One common succulent plant with thorns in desert biomes is the Barrel Cactus (Ferocactus). This plant has thick stems covered in sharp spines that help protect it from predators. Another example is the Ocotillo (Fouquieria splendens), which is a spiny desert succulent that grows long, thorny branches.
European tradition says that the crown of thorns was made from the hawthorn tree. Hawthorn bushes have huge, gothic looking thorns. Hawthorn is not native to the middle east, however. But the tradition survives and even results in hawthorn being used as a form of traditional protection against vampires.
The ocotillo plant is a common desert plant found in the southwestern United States and Mexico that has thorns but is without leaves. It is known for its long, vertical stems covered in sharp spines, which help reduce water loss and protect the plant from herbivores. The plant produces leaves only after a rainfall to maximize its photosynthetic potential.
Having leaves instead of thorns would increase the surface area available for transpiration and could lead to excessive water loss in a desert environment. Thorns are adapted to reduce water loss by minimizing leaf surface area, so having leaves instead could make the plant less suited to arid conditions.
Is there a rose bushthat has no thorns.
No, the vast majority of plants in the desert are not succulents. They are typical plants that have developed other means of living in an arid environment.

Some desert plants have spines or thorns, some have a bad taste and some are toxic if eaten.
it is their evolutionary defense against attackers. In a desert environment, water is very scarce. Therefore, every small amount of water absorbed by plants is indispensable to plant survival. The purpose of thorns is to protect the fleshy stems (which contain water) of the cactus from predators.
1. Roots are shallow and spread over a large area to collect as much water as possible. 2. Plants can store nutrients and water needed. 3. Have thorns instead of leaves to minimize water loss and keep animals away.
In the deserts of North America, some 'spiky plants' are yuccas, agaves and sotols. Many other plants have spines and thorns.
