Islands: F, Faial; P, Pico; SJ, São Jorge; T, Terceira; SM, São Miguel; SA, Santa Maria; LP, La Palma; EH, El Hierro; LG, La Gomera; Te, Tenerife. Island ages are maximum ages in Myr taken from Caujapé-Castells (2010). Taxa: MA, P. malvifolia subsp. malvifolia; CA, P. malvifolia subsp. caldeirae; PA, P. papyracea; MU, P. murrayi; ST, P. steetzii; EC, P. echinata; CR, P. cruenta. A black circle is used to indicate the presence of the island Graciosa, which does not host any populations of P. malvifolia and, therefore, was not sampled in this analysis.
