The small leaves of antennaria microphylla
grow mostly around the base; they are spatulate, with pointed tips, and covered by a coating of fine silvery hairs. Those along the stem are smaller, narrower and point upwards. The upper part of the stem branches into 6 to 13 flower heads that have disc florets only, either with stamens or pistils, white or pale pink. These are enclosed by several rows of broad, pointed white phyllaries; the color being one way to distinguish this species from the similar antennaria rosea
, which has pink phyllaries. The stems also have a covering of hairs.
