Viguiera dentata var. lancifolia is the subspecies native to Arizona and Mexico only

Viguiera dentata var. dentata is also native to Arizona and Mexico, and adds Texas and New Mexico as well.

The genus Viguiera is distinguished by hairy filaments on the stamen. The sunflower aspect is evident in the large, heart-shaped toothed leaves, with Viguiera dentata having the most sunflower-like leaves.

Leaves opposite (proximal) or alternate (distal); petioles 10-55 mm; blades ovate or rhombic-ovate to lance-ovate or lanceolate, 3.5-12.5 × 1-8 cm, margins serrate or serrulate, faces strigose.

It's difficult to see the serrate margins but a photo of the leaves do show it a little, however the leaf shape is wrong being like an ace of spades shape but the description indicates they can be otherwise. The flowers don't seem to match well, the centres are more daisy-like but at what stage are the flowers at? If they were forming seeds in the middle wouldn't the petals have dropped? There's good photos showing the backs of the flowers on the above link.
