<p><span>California contains exceptional biodiversity in geography and plant life, including numerous endemic species, some of which are cryptic. The </span><i>Oenothera deltoides</i><span> Torr. & Frém. species complex represents a prime example of cryptic diversity. Here, we recognize a new subspecies of </span><i>Oenothera deltoides</i><span>, </span><i>O. deltoides</i><span> subsp. </span><i>julpunensis</i><span> S.F.Jones, subsp. nov., that is a local endemic of windblown sand deposits on the eastern Antioch Dunes sand sheet in the San Francisco Bay-Delta region of California, USA. With the goal of providing clarity to managers of listed species and better understanding of California's diverse flora, we addressed the puzzle of </span><i>O. deltoides</i><span> in the region by combining range-wide field surveys with modern genomic tools. We describe the proposed subspecies, its ecology and distribution, and discuss its conservation. As a somewhat cryptic local endemic with small population size and disappearing habitat, the proposed subspecies would benefit from conservation and management to persist as a member of the California flora.</span></p>
