Linear models examining foliar morphology in Euphorbia tithymaloides (focused on variables with highest loadings on three PCs) in relation to climate after variation due to subspecies was eliminated (response variable are the residuals from morphology ~ subspecies models). Colours represent subspecies (red, E. tithymaloides subsp. angustifolia; blue, E. tithymaloides subsp. padifolia; green, E. tithymaloides subsp. tithymaloides).
