A comparative morphogenetic study of reproductive organs of chrysanthemums is conducted using morphological analysis. Morphological changes during the development of a generative shoot and organogenesis from first through ninth phases were described. The flat apex becomes spherical in form. An inflorescence apical meristem initiates involucral bract. An initiation of floret primordia is followed an acropetal sequence. Floral meristem produces corolla, then 5 staminata primordia and two-lobed pistillata primordia. The ray floret and the disc floret both form 5-lobed corolla, but 2 lobes of the corolla of the ray floret stop their growth. Staminata primordia of the ray floret produce sterile staminodia or do not continue their development. At phase IX during flowering, 4 stages are identified. A dehiscence of introrse anthers and anthesis occur in a closed disc floret. There are protoandria and different arrangements of mature anthers and mature stigmata in disc florets .
