The development of a malformed Baccara rose flower was compared with that of a normal one. A dormant apex completes most of its vegetative differentiation before bud break. In transition to flowering the dome-shaped apex flattens, and intense activity at its margins produces sepals, petals and stamens. Differences in rates of cell division cause invagination of the central part of the receptacle. A ring-shaped non-functional nectary is formed in the normal flower between the stamens and the carpels. This nectary is absent in the malformed flower. Instead, secondary florets bearing mainly carpels proliferate in this region. © 1975 Annals of Botany Company.
