Pimelea sessilis is an erect shrub that typically grows to a height of {{cvt|15–40|cm}} with dense tufts of hair in its leaf axils. The leaves are sessile to almost stem-clasping, narrowly elliptic to almost round, {{cvt|6–15|mm}} long and {{cvt|6–9|mm}} wide. The flowers are arranged in heads on a peduncle {{cvt|5–25|mm}} long, surrounded by 4 broadly elliptic to almost round involucral bracts {{cvt|7–15|mm}} long and {{cvt|6–14|mm}} wide, each flower on a pedicel {{cvt|1.5–2.0|mm}} long. The flower tube is {{cvt|8–11|mm}} long, the sepals {{cvt|3–5|mm}} long, and the stamens are longer than the sepals.
