Helichrysum

Helichrysum bellidioides, copyright Ghislain118.

Belongs within: Gnaphalieae.

Helichrysum is a genus of everlastings widespread throughout the Old World (Black & Robertson 1965). Members of the section Xerochlaena are prostrate creepers with herbaceous or very softly woody stems (Allan 1961).

Characters (from Black & Robertson 1965): Involucre from hemispherical to cylindrical, of many unequal bracts in several rows, bracts usually rigid and sometimes with spreading small or conspicuous coloured laminae; flowers either all bisexual, or majority bisexual with comparatively few female ones in usually one outer row; flowers usually shorter than or not longer than involucre; rarely heads clustered without any general involucre. Pappus-bristles simple or barbellate or sometimes plumose towards summit but not plumose from base, usually united in a short ring.
