Photo of an emergent aquatic plant with grassy leaves and a spadix of miniscule flowers.

Just 2 spp in the genus Acorus (#Acoraceae & #Acorales), sister to all other monocots. It has iris-like foliage & spikes of perfect flowers subtended by a spathe. Brood-site #pollination by #flies in 1 sp. & #beetles in the other. : A. calamus, Giles Watson CCBYSA2 #OddMonocot #Botany 🌾🧪
