4650’. Growing in volcanic sand with some minor diatomaceous components. Other vegetation includes Psorothamnus polydenius, Sarcobatus baileyi, Tetradymia canescens, plus some annual Eriogonum. Old stems arcing upward and inward.

Extent of population here appears restricted to a roughly 15x100 meter area; a two track cuts through the occurrence with at least one enterprising individual growing from the center of that.

As far as I’m aware, this is just about the northernmost reach of the species’ range.
