Small population (6 plants) near building entrance at Steele/Burnand Anza-Borrego Desert Research Center. Population is being monitored and removed. Two years ago there were 40+ plants. Probably introduced with cultivated natives planted around the building.
Anza-Borrego Foundation property. Outwash from Glorietta Canyon.
Survey of a large private parcel south of Deep Well. Surprising plant diversity here, but I was dismayed to find Oncosiphon. I pulled it.
Second location of this noxious weed. There were several plants here. I didn't pull them this time but I should have. I'll go back and get them.
I hope this i.d. is correct because I pulled it up and took it with me

From a big population being treated with chemicals and hand pulling.
First time spotting this plant in the city. It certainly smelled interesting when mashed up, like fennel or dill.
