· Simply due to the location where the species is found.
· A coastal species may have a different pollen shape to help with things such as salt resistant while a species found inland will be more heat resistant.
· It just depends on the type of environment in which the plant has adapted.
It also has something to do with bees. Bees have to carry pollen therefore telling how honey is collected
