The flower is first.
In turn the fruit then the seed.
There is a pattern.

With cloudy "cooler" weather, I hike. Digger bees. Cactus wrens. Lizards galore. Dry grass. The only flowers in the desert right now are from the chain-fruit cholla, saguaro, or, above, the barrel cactus.

That's Picket Post Mountain peeking out from behind the saguaros.

(I made the photos extra large so be sure to click on them.)
