Not marshmallow!

Globemallow (genus Sphaeralcea) 

Rosemallow hibiscus coulteri

There is a third 'mallow' in the canyon. Indian Mallow or (genus) Abutilon. Lots of it along the road into Sabino Canyon. Not blooming yet for the post-monsoon, but look for the heart-shaped leaves and the remaining dried out seed pods - round, with (what reminds me of) a star in the middle.
