Consequences of within-plant variation for interacting animals -- Phytophagous animals' adiscrimination among organs of the same plant can lead to the most profitable choice but has attendant costs that may influence their overall performance and promote among-plant selectivity -- Fitness consequences of subindividual variability in organ traits for plants -- Subindividual variation in the characteristics of reiterated organs may influence the fecundity or vegetative performance of plants, and through this mechanism individual fitness differences may arise as a consequence of variation in the extent and organization of variability -- Evolutionary implications of within-plant variability in organ traits -- Subindividual multiplicity of organs can affect the evolutionary trajectory of organ traits by setting upper limits on responses to selection, opening the possibility of selection by animals on plant-level variability, and conditioning the size of realized phenotypic space at the individual and population levels.

Introduction -- Which traits vary within plants? -- Many different features vary across reiterated structures of the same plant -- Continuous within-plant variation of reiterated structures -- The extent of subindividual variation in continuously varying leaf, flower, fruit, and seed traits is assessed -- Distribution of subindividual variability in time and space -- How are variants of reiterated structures organized along temporal, spatial, and architectural axes? -- Causes of subindividual variability -- Mutations within individuals and organ-level responses to environmental cues are the main classes of remote causes of within-plant variability in reiterated structures -- Organismal mechanisms of subindividual variability -- Ontogenetic contingency, the interplay between inherent architecture and environmental milieu, and developmental stochasticity are mechanisms responsible for within-plant variability of reiterated structures -- Subindividual variability as an individual property -- The Haldane-Roy conjecture is verified and extended: individual plants have not only their characteristic means, but also their characteristic standard deviations and characteristic spatial patterns of within-plant variation
