M. montioides, as currently circumscribed, is a highly variable taxon that has long been considered by some to contain within it coherent forms that will hopefully soon be more widely recognized and accepted as separate species, due to ongoing work of Naomi Fraga and others. In particular, Naomi F. refers to this plant by resurrecting an earlier name, M. discolor. The plant in this post was near (at?) a location Naomi has listed for M. discolor, where I found it growing with conspicuous patches of Phacelia exilis.
