Palyno-morphology of the genus Geranium (Geraniaceae) and their systematics implications Using Scanning Electron Microscopy

Pollen morphology of 23 species belong to Geranium have been study in details, which represent eight sections of the two subgenera i.e., G. sect. Dissecta, Geranium, and Tuberosa of subgen. Geranium, Divaricata, Lucida, Ruberta and Trilopha of subgen. Robertium. These plant species were collected f...
