Phacelia mammillarensis is an annual herb with simple oblong to lanceolate leaves up to 7 mm (0.3 inches) long, covered with small glandular hairs. Inflorescences are terminal and lateral, each in the shape of a "scorpoid cyme", i.e. curled in a spiral like a scorpion's tail or like a half-open fiddlehead fern. Flowers are yellow to white.Atwood, Nephi Duane. 1973. Two new species of Phacelia (Hydrophyllaceae). Phytologia 26(6): 437–438. 1973.
