Evolution of embolism and drought resistance in the biofuel species Silphium perfoliatum- Josh Randall

The Genus Silphium is composed of two subgenera, Silphium and Composita, which are distinguished by growth habit: as either tall sunflower-like or geophytic herbs, respectively. Both groups have scleramorphic leaves as well as high densities of trichomes. Species in Composita are found in drier habitats, and the biofuel species Silphium perfoliatum is a member. The
