In the hanging gardens habitat.

Somehow growing in a heavily disturbed sandy lot filled with Erodium and Tribulus.

Final photo (of the fruit) is from a different individual about 100 meters to the east and up the hill.

Highly stunted? Saw mature individuals that looked very similar to Erythranthe cardinalis (bilaterally symmetrical red flowers) growing out of safe reach on slope beneath Corona Arch.
