Time-calibrated molecular phylogeny from Leslie et al. (2012) showing the distribution of pollination-stage seed cone morphologies across Pinaceae. These morphologies include Abies-like (bract scales longer), Picea-like (ovuliferous scales longer) and intermediate (bract and ovuliferous scales roughly equal in length). The width of the black triangles is proportional to the relative species richness among extant genera, and the apex of the triangle corresponds to the estimated crown divergence ages within that genus. The relative sizes of bract scales and ovuliferous scales are roughly constant within extant genera. Pg, paleogene; Ng, neogene.
