Largest plant, woody stems, most plants growing on exposed/rocky slope.  In all I could only find about 6-7 plants.  Hiking trail is at the immediate left.  Within probably about 100 feet of residential fence.
 
 

Not the best photo but shows the foliage pretty well.  Same plant as above.

Best picture re: flowers.  You can't tell from this picture, but anthers did appear to be U-shaped.
 

This was the only plant not growing by itself and was growing apart/north of the others off the trail.  It was being invaded by Dalmation toadflax (see lower left re: some of the weeding I did!).  Note the invading rock garden plant in front of it and in the upper left.  This plant appears to have either escaped or was initially planted intentionally possibly on the slope whether the trail starts on Teton Dr. and it also being used in the landscaping of some nearby homes.  (Therese Meyer has identified it as Euphorbia myrsinites and urges its removal; Ty Harrison has further confirmed.)   It has gobbled up much of the possible habitat on the ridge and appears to be spreading rapidly. Eriogonum umbellatum grows just a little further up from here on this ridge.
 

Overall habitat shot looking to the south from the rocky ridge.  Dalmation toadflax was/is invading along with cheatgrass (?).  Two-three small plants can be seen in the middle/upper left.  The large plant shown above is also visible (middle/upper).
