EVOLUTION AND ADAPTATION OF INFLORESCENCES IN THE HYDROCHARITACEAE

American Journal of Botany, 1970
Inflorescence evolution in the Hydrocharitaceae has involved modification of a complex sympodial system by condensation, loss of bracts, fusion of pedicels in some cases, adnation of branches to the peduncle in others, and progressive loss of later‐formed flowers resulting in one‐flowered inflorescences in many instances.
