Bolander's Mule Ears

Agnorhiza bolanderi is known only from the foothills of the Sierra Nevada, where it evidently grows only on serpentine soils.

Plants (10–)15–30 cm. Stems decumbent, seldom distally branched. Cauline leaves: blades oblong, ovate, rounded-deltate, or subor-biculate, 4–12 cm, bases ± truncate or cordate, margins entire, faces glabrous (shining, finely gland-dotted, ± glutinous). Heads held among or beyond leaves. Involucres ± campanulate, 15–25(–30+) mm diam. Outer phyllaries ovate to ovate-lanceolate, 10–40+ mm (seldom surpassing ray corollas). Ray florets (7–)8–12, laminae (12–)20–30(–35) mm. Cypselae 7–9 mm, glabrous; pappi 0 or coroniform, 0.1–0.3 mm. 2n = 38.
