Thysanocarpus laciniatus

A species found primarily in California, but peripherally in Nevada & Arizona. The laciniate basal leaves for which it is named are by no means a universal feature of the species. It is often quite similar to Thysanocarpus curvipes subsps. amplectens and eradiatus but without the prominently auriculate leaves of those taxa.
