Leaves are arranged opposite, narrowly elliptic {{cvt|6–37|mm}} long, {{cvt|1-10|mm}} wide, smooth, uniformly grey coloured, sometimes paler on the underside. The inflorescence consists of numerous flowers in a spherical shaped head.

The bisexual white flowers are a floral tube, {{cvt|10-12|mm}} long, smooth inside, with long upward hairs above. The sepals spreading, {{cvt|3–5|mm}} long and smooth on the inside. The pedicel is hairy and the stamens may be longer or shorter than the sepals. The fruit are a dry nut thickly covered with fine hairs and forming into a densely clustered conical head.
