"Hesperevax sparsiflora" is a species of flowering plant in the daisy family known by the common name erect dwarf cudweed. It is native to California and Oregon, where it grows in several habitat types including sandy coastal areas and the serpentine soils of inland hills. This is a small woolly annual herb reaching maximum heights under 18 centimeters. It has oval to rounded or scoop-shaped leaves on short petioles which vary in morphology across varieties. Small flower heads appear between the leaves. They contain greenish or whitish disc florets.

There are two varieties:
*"H. s." var. "brevifolia" (short-leaved evax) is an uncommon coastal variety with leaves generally under a centimeter long
*"H. s." var. "sparsiflora" is a longer-leaved variety which is more common but limited to California
