I have found good pictures of nectarine on the web. That looks like the answer. As the fruits mature I can be more certain since people tend to post pictures of mature fruit. I'm pretty confident now.

Pluots are available in the grocery stores here now, Feb 22. Try a few from now, and a few more from 2 weeks from now, then another two weeks till you have eaten about 2 dozen and saved the pits in moist soil in a baggie in the fridge. They will need about 120 days or so in the fridge, so label the baggie with the date the last ones went in. Check on them every month or so and add a few drops of water if the soil gets a bit dry...don't overdo water though, as they need air too. The soil should be just moist enough to be crumbly but not soggy. Watch for sprouts after the 3rd month and pot any that are already sprouted. Some folks will place a seed on its edge and wrap it smartly with a hammer on the seam, cracking the stone. if you have a light touch, it will give you a few more sprouts. If you hit them too hard you will damage the seeds inside the stone and they will die later.
