Blennosperma bakeri is a rare species of flowering plant in the daisy family known by the common names Baker's stickyseed and Sonoma sunshine.

It is found alongside other rare vernal pool plants including the Sebastopol meadowfoam, Limnanthes vinculans, and Burke's goldfields, Lasthenia burkei.

Threats to its survival include the alteration of its habitat for development, road maintenance, grazing, and agriculture, as well as collecting, herbivory by thrips, and invasive plants.

The leaves are 5 to 15 centimeters long and linear in shape with lobes near the ends.

Around the edge of the head is a fringe of yellow ray florets with red stigmas.
