Notes: Endemic to se AZ and sw NM. Phacelias are often hairy all over with pinnate leaves and most have a inflorescence curled like a scorpions tail (scorpoid cyme). They are notoriously difficult, make sure you have leaves, flowers and mature fruits to correctly identify most species. This species though, fairly distinct by its prostrate-decumbent habit; leaves deeply pinnately lobed and not reaching the inflorescence, most of them basal, the ones on stems reduced; the inflorescence shorter than many species; and a white to pale bluish, bell-shaped corolla(not funnleform).
