I've written about plants in the Mallow family before (and I'll do so again), but these photos from Marty really show the fruits in their glory.
All together now: The fruit is the thing with the seed(s)!

These are the fruits of Wild (aka Desert) Cotton (Gossypium thurberi). Note the chambers; they contain the seeds. You can even see the sparse cotton fibers inside the chambers. Very cool.

These fruits are from the Indian Mallow Abutilon reventum. There are four species of Abutilon in Sabino; this one has large, very soft leaves. And the fruits are rounded at the top, as you see here, and have multiple (more than 5, usually 10-12) chambers.
