The stimulation of certain unfertilized female florets (u.f.f.) of Alocasia brisbanensis is reported. The affected florets occur adjacent to or around berries (fertilized female florets). The stimulated florets are larger than the unfertilized florets (but smaller than the berries) and reddish orange in color rather than the smaller orange- colored normal u.f.f., although all u.f.f. later usually turn reddish. The stimulated florets are seedless. It is suggested that a growth substance of unknown composition causes the stimulation from the maturing berries.
