Phacelia cryptantha resembles many species of the cryptantha genus, in having a coiled inflorescence, and long bristles on the leaves, stems and calyces. Stems grow upright, sometimes with a few branches, and have a dense covering of hairs, some glandular. Leaves are long, stalked, and those on the stem are compound, divided into an odd number of coarsely-toothed leaflets. Lower stem leaves may be compound, or lobed.
The green calyx lobes are linear, unfused, and widely spreading. The narrow, bell-shaped corolla is colored pale blue to lavender, and contains five stamens with pale purple filaments and whitish anthers. The corolla is about twice as long as the calyx lobes.
