Fruit-discharge type of forty species of Asian Geranium were examined and their evolutionary trends and taxonomic system were discussed. Two main types of seed discharge in Geranium are made the basis of its divison into subgenera: Geranium subgenus Geranium, with a ballistic expulsion of the seed from mericarp, Geranium subgenus Robertium, with forcible discharge of the mericarp with the seed in it, separately from the awn. Variants of the seed ejecting type permit the division of Geranium subgenus Geranium into three sections. Section Ceranium, these has bristles at the base of the mericarp for prevent the seed from dropping from the divergent mericarp. Section Dissect, these has prongs at the base of the mericarp far prevent the seed from dropping from the divergent mericarp. Section Tuberosa, these has no bristles and prongs at the base of the mericarp, instead, retained of seed in pre-explosive interval by twist. Geranium subgenus Robertium was divided into two sections, Section Ruberta, with deeply wrinkled on the surface of mericarp at the time of discharge. Section Batrachioides, and section Trilopha, without wrinkle on the surface of mericarp at the time of discharge. According to the seed discharge, subgenus Geranium is thought to be more advanced than subgenus Robertium.
