The upper leaves of Helichrysum lineatum have raised tips around the small, slightly spaced clusters of flowerheads. The visible leaf parts are variable in shape and size. Some have faint green showing through the hairs. They all have hairs.
The stubby, yellow-topped flowerheads are cylindrical to barrel-shaped, not differing much in size unless they are still to open or finished flowering and brown all over. The brown bracts are woolly like the leaves. The florets are almost always bisexual, female ones being rare (iNaturalist; iSpot; www.keys.lucidcentral.org).
