These seeds were a bit of a mystery for me.

I knew the seeds were in these button-like seed cases on the plants.

But what did the seeds look like?

I pulled one apart. Are these the seeds?

No, those are the envelopes the seeds come in. The seeds are circular and pretty tiny.

Hint:  this is a desert plant that is related to hollyhocks.

Do you know what it is? Don’t be shy to leave your guesses in the comments.

Edit:  The answer is now posted.
