Phacelia sivinskii N.D.Atwood, P.Knight, and T.Lowrey

A gypsum endemic of central New Mexico, formerly included in Phacelia integrifolia and most readily distinguished from that species by having narrowly tubular corollas. Placement of the southern populations (Sierra County, Lincoln County) is somewhat uncertain. It is possible they are not this species, but if so I do not know what else one would call them.
