The results of studying the morphological characteristics of the flower, fruit,
pollen grains, and seeds between some of Hypericum genus species, show that
there are relevant morphological differences among the studied species, which
can be considered as taxonomical criteria for distinguishing the studied species
of Hypericum genus from each other.

walls between some of hypericum genus spceis (family clusiaceae), show that
there are rel
