This obs contains examples of basal rosettes that six days earlier had their leaves dead flat on the ground.

Survey of the first 2.0 miles of the PCT north of S22 for Plagiobothrys and Cryptantha species. For details, see:

Don Rideout and I did a special survey of the first 2.0 miles of the PCT north of S22 for Plagiobothrys and Cryptantha species. We had seen plants that looked much like P. tenellus six days earlier here, so we were specifically looking for P. tenellus to verify that determination from the nutlets.

However, despite careful surveying, we only found P. arizonicus and C. intermedia. The plants that had looked like P. tenellus six days earlier, from their small basal rosettes, no longer looked like P. tenellus! The basal rosettes of those plants were mostly no longer present, as the plants withdrew energy from their basal leaves for flowering.

We checked a lot of plagios, and all had circumscissile calyces. Out of the dozens we checked, we have posted seven of them at iNat from this trip. All of our iNat posts from this trip:

I speculate that these plants of P. arizonicus had unusually-small basal rosettes because of the unusually-cold weather during their growing season.

The last pix in this post was supposed to show a circumcised calyx, but the camera decided to focus on my thumb instead of the calyx. With some imagination, you might be able to see two developed nutlets, and two aborted nutlets.

Alas, the developing bud now makes it clear that this was not a Caulanthus, and is almost surely H. glabra. I was hoping for something more interesting.

I've never seen H. glabra in chaparral like this area.

Don found another location with this species farther along the trail that looks more like H. glabra:

I photographed 29(!!) young ocotillos seen in a 1.6 mile hike on the northwest side of Harper Flat, and I'm sure I missed a number of young ones farther from my path. This area clearly had good recruitment in the last decade.

A number of these young ocotillos have bent new stem segment growth.
