(E) Normal tassel. (F-H) ifa1-r zag1-mum1 tassel. (G) ifa1-r zag1-mum1 floret reveals an ectopic spikelet arising from the center of the stamen whorl where the aborted pistil should have been. (H) The ectopic spikelet from G was opened to reveal staminoid florets arising from the axils of leaf-like organs. Arrows in G and H point to one of the lodicules (lo).
