Linear models examining foliar morphology in Euphorbia tithymaloides (focused on the three main PC axes that capture 96.7% of variation in morphology) in relation to climate eliminating variation due to subspecies (response variable are residuals from morphology ~ subspecies models). Colours represent subspecies (red, E. tithymaloides subsp. angustifolia; blue, E. tithymaloides subsp. padifolia; green, E. tithymaloides subsp. tithymaloides).
