Morphology General Habit
Slender tufted annual.
Morphology Leaves
Leaves linear, 2–7.5 cm. long, 1.5–6 mm. wide, thin, acute or less often acuminate.
Morphology Reproductive morphology Inflorescences Scape
Scapes varying from few to ± 50, often slightly flexuous, 7–25 cm. high, 4-ribbed, the ribs forming narrow wings; sheaths ± as long as the leaves, the limb with a delicate hyaline acute tip, soon splitting.
Morphology Reproductive morphology Inflorescences Capitulum
Capitulum globose, 3–5 mm. diameter, greyish white, the pale female petals showing among the white-hairy floral bracts; involucral bracts shorter than the capitulum width, 4–5 spaced in one circlet (best seen in very young, still hemispherical capitula), ovate-oblong,obtuse, thin and hyaline, crumpled and obscured by the expanding flowers and apparently absent at maturity; floral bracts narrowly oblong-cuneate, black, scarious, concave but not keeled, densely white-pilose on the upper blade, acute; receptacle pilose, often thinly.
Morphology Reproductive morphology Flowers
Flowers 3-merous, 1.0–1.2 mm. long, mainly female. Female flowers:sepals black, narrowly oblong, one slightly to definitely smaller, concave, lightly keeled and narrowly winged above the middle, white-hairy towards the acute tip; petals and ovary subsessile; petals narrowly oblanceolate-oblong, subequal, pallid, white-hairy around the tips, glands small, often absent on the median petal. Male flowers:calyx spathate, black, the free sepal-tips obtuse, white-pilose; petals small and included within the calyx, white-pilose, glands very small; anthers black.
sex Male
