Answer:
The leaves in Bikaner are mostly spines in shape and structure whereas in Shimla normal shaped leaves can be seen.
Explanation:
'Cause annual rainfall in Bikaner is very less relative to Shimla.So, the trees or plants of Bikaner tend to minimise their surface area of leaves which is modified to spine in order to have least transpiration of water through their plant body to survive even in those scanty rainfall areas.
Shimla has sufficient rainfall to conduct normal transpiration rate through the leaves of the trees of that area
