The small, greenish-grey leaves of eriophyllum wallacei
grow at closely-spaced intervals all along the short stems and right beneath the flower heads, a feature which distinguishes it from some similar species like eriophyllum lanatum
that have only basal leaves. Stem, leaves and the bracts beneath each flower have quite a dense covering of fine, fluffy wool.
Flowers measure about one inch in diameter and are formed of 5 to 10 yellow ray florets, dozens of tiny yellow disc florets, and 5 to 10 green-gray phyllaries. When fully open the ray florets bend back slightly, below the plane of the central disc. The rays have a blunt, flattish tip with two notches, and two lengthwise grooves.
