Descriptions
Helichrysum bellidioides (G.Forst.) Willd.
Main stems prostrate and rooting, up to c. 6 dm. long and 5 mm. diam. (sts lianoid among shrubs); branches decumbent, with rather open cottony tomentum. Lvs 5-6 × 3-4 mm. (occ. up to 1·5 × 1 cm.), broadly rounded and abruptly mucronate at apex, cuneately narrowed to flattened semiamplexicaul petiole; glab. above when mature, clad in appressed cobwebby tomentum below. Scapes slender, densely woolly-tomentose, up to 10 cm. long, with ∞ narrow-oblanceolate ascending bracts. Capitula c. 2-3 cm. diam.; outer phyll. linear-mucronate, densely softly tomentose on back; inner chartaceous, linear-oblong, 30-50, up to 1 cm. long, white, obtuse, abruptly narrowed to thin stramineous claw, tomentose on back. Receptacle 4-5 mm. diam., shallowly to distinctly convex, alveolate; perfect florets ∞, ♀ few. Achenes compressed, striate, glab. when mature, up to 1mm. long; pappus-hairs subequal, up to 4 mm. long.
Helichrysum bellidioides (G.Forst.) Willd.
Decumbent to ascending herb, (3)-5-15-(20) cm tall; prostrate stems rooting; erect flowering stems tomentose, 0.75-2 mm diam. Lvs spreading, distant, usually glabrous on upper surface, sometimes sparsely to densely white-tomentose, tomentose on lower, apetiolate, obovate, mucronate, amplexicaul, 5-9-(15) × 2-4-(6) mm. Uppermost lvs on flowering branches becoming narrower and finally narrow-oblanceolate, and more distant. Capitula 14-22-(25) mm diam., solitary, pedunculate. Middle involucral bracts (5)-6-9-(12) mm long; stereome tomentose; lamina longer, membranous, glabrous, elliptic to oblong, obtuse, milky white or rarely tinged rose or cream, radiating. Disc pale yellow. Achenes glabrous, obovoid-cylindric, slightly angled or compressed, 0.8-1.4 mm long.
