Helichrysum unicapitatum
Mantıçiçeği
Caespitose, suffruticose plants, mat-forming, up to 70 cm in diameter, white-felted, eglandular. Flowering stems 0.4–2 cm, slender, erect, arising rom short thick branching caudices. Basal leaves forming dense rosettes which arise directly from woody rootstock, 4–7 x 2–5 mm, elliptic-orbicular, concolor, densely tomentose, margin flat. Cauline leaves 5–8, more or less adpressed to stem, alternate, decreasing in size towards synflorescence; uppermost ones 4 x 1 mm, narrowly spathulate to linear, basal ones 6 x 2 mm, oblong to elliptic. Synflorescence terminal, one solitary capitulum, rarely 2–3 clustered. Capitula 4–5 x 5–6 mm, broadly campanulate, heterogamous, disciform, with 35–65 yellow florets; pistillate florets 3–8, marginal; hermaphroditic florets 30–60, central. Involucral bracts regularly imbricate, more or less adpressed, arranged in 4 rows, brownish, papery, tomentose only in middle, stereome divided; outermost bracts 3–4 x 1.2–1.5 mm, ovate, obtuse; innermost bracts 4–5 x1–1.2 mm, spathulate, obtuse. Corolla with tube glabrous, lobes 5, acute, outside covered by short stipitate-glandular hairs; corolla of pistillate florets with tube 3 mm long, lobes 0.3 mm long; corolla of hermaphroditic florets with tube 3.5 mm long, lobes 0.5 mm long. Style thickened at base, gradually narrowing upwards, in pistillate florets 2.5 mm long and in hermaphroditic florets 3–4 mm long. Stigma 0.8–1 mm long, with apices slightly thickened. Anthers ecalcarate, 2 mm long, apical appendage acute, basal appendages long-tailed, 0.2 mm long. Pollen grains 19–20 μm in diameter, spheroidal, echinate . Achenes ca. 0.7–1 mm long, cylindrical, light brown, with some scattered duplex hairs. Pappus bristles ca. 4 mm long, whitish, uniform, uniseriate, caducous, with ca. 20–25 barbellate hairs and short patent cilia at base; apical cells.
Flowering June–August; fruiting July–August.
Endemic.
