Protandry

Male organs (stamens) active first upon opening of flower
Towards flower senescence, stigma becomes active and stamens wither (from bottom of inf. upwards)

'Female' flowers produce the most nectar and are most attractive, so as to entice pollinators to start from the bottom and work their way up

Common in species with dense spikes

Families: Iridaceae and Asteraceae
