The evolution and diversification of the red oaks of the California Floristic Province (Quercus section Lobatae, series Agrifoliae).

Premise Of The Study: The California Floristic Province (CA-FP) is a unique and diverse region of floral endemism, yet the timing and nature of divergence and diversification of many lineages remain underexplored. We seek to elucidate the evolutionary history of the red oaks of the CA-FP, the Agrifoliae.

Methods: We collected PstI-associated RAD-seq data as well as morphometrics from individuals of the four species across their ranges, including varieties and hybrids.
