This chapter focuses on the ways in which subindividual variability is distributed in time, and among different parts and spatial locations within a plant. A sequential component arises whenever individual plants produce variants of the same organ over the same season or, in the case or perennials, in different years. The simultaneous component is generally due to plants producing multiple variants of the same organ simultaneously or over a relatively short period of time, in such a way that organ variants are borne at the same time by individual plants. The relative importance of annual variation as a component of sequential within-plant variation can be most easily examined for leaf characteristics on deciduous plants. Spatial analyses of within-plant variation in organ features reveal that after the broad-scale variation disclosed by gradient-oriented analyses has been statistically accounted for, much intraplant variation remains, occurring over very restricted spatial scales.

Keywords: subindiviual variability; spatial locations; multiple variants; within-plant variation; spatial analysis
