* Root : shoot relationship according to Groff and Kaplan's classification: class 1, bipolar species; class 2, shoot-rooting species; class 3, root-sprouters; class 4, species with both the ability to form roots from shoots and root-sprout.
† Sprouting ability after fire or clipping: 0 = non-sprouters (when 0–20 % of the individuals resprouted, but most resprouts died after 1 year of clipping); and 1 = resprouters (when >20 % of the individuals resprouted and most resprouts survived). Sources of information: a = authors' personal observation through experimental clipping or field prospects, b = Villar Salvador (2000), c = Guerrero Campo (1998), d = Riera (2000), e = Montserrat-Recoder et al. (1984), f = A. Escudero, pers. comm., h = Cucó (1987).
