Helichrysum
Annual or perennial herbs or shrublets with capitula solitary, in small
groups or in tight clusters. Capitula are heterogamous disciform (or rarely
homogamous discoid). Involucral bracts are generally colourful: white, yellow,
red, pink, straw-coloured or brown. Flowers 2–2500. Female florets are yellow,
pistillate, filiform, and are fewer than the disc florets. Disc florets
perfect. Pappus bristles are generally in one row and not fused at the base.
585 species worldwide – mainly Africa & Madagascar, also Europe & Asia.

on branches; 24–28-flowered. Involucral bracts milky white, reflexed in
upper part. Florets yellow. Cypselas very densely hairy, with twin-hairs.
Monotypic Western & Eastern Cape endemic.
Distinguished from Helichrysum by its scale-like leaves and lack
of female florets.
