Acmispon wrangelianus

A spring annual found in California, better known as a member of the genus Lotus. Similar to Lotus (Acmispon) humistratus, but with the leaves sparsely strigose rather than more densely pilose. My identification of this plant is not entirely certain; if accurate, it is apparently a new record for Arizona.
