Parallel speciation is documented in animals multiple times. although, in plants the parallel speciation cases are not much which suggest that plants are not prone towards the parallel speciation, but this also indicates that there are not enough empirical studies available which are based on rigorous evaluation and testing, like in the cases of animals.
