Serruria fasciflora or common pin spiderhead is a species of flowering plant in the family Proteaceae. It is a sprawling to upright shrublet of 40 cm to 1 m (11⁄3–31⁄3 ft) high and about 1⁄2 m (12⁄3 ft) wide. It has finely divided, upward curving leaves with thread-thin segments and clusters of sweetly scented heads, each consisting of five to seven silvery pink flowers, that may be found year-round, but mostly from May to December. It is a rather widespread and common species, that is restricted to the south of the Western Cape province of South Africa.

Serruria fasciflora is a much branched, sprawling to upright perennial shrublet of 40 cm to 1 m (11⁄3–31⁄3 ft) high and about 1⁄2 m (12⁄3 ft) wide, with purplish, initially felty or powdery hairs that are lost later on. It has sparsely hairy, twice finely divided in the upper half to two thirds, green leaves of 3–7 cm (1.2–2.8 in) long and 21⁄2–31⁄2 cm (1.0–1.4 in) wide. The furthest segments up to about 2 cm (3⁄4 in) long, awl- to almost threat-shaped with a very pointy tip.

It bears a broad corymb of ten to fifteen flat-topped flower heads on a short hairy stalk, that is enclosed by leaves. The stalks of the individual flower heads are 0.65–1.9 cm (1⁄4–3⁄4 in) long, slender, densely softly hairy, with a single awl-shaped softly hairy bract of about 4 mm (0.16 in) long just below the head. Each flower head is about 8 mm (1⁄3 in) across, consists of five to seven silvery pink, sweetly scented flowers, and is subtended by a lance-shaped floral bract.

The felty bract subtending the individual flower is more or less oval, with a thickened, later hairless glandular tip, about 3 mm (0.12 in) long. The 4-merous flowers are slightly curved before they open. The lower part, that remains merged when the flower is open, called perianth-tube is covered with long soft hairs and about 11⁄2 mm (0.06 in) long. The middle part (or claws) consists of four segments each of about 1⁄2 cm (0.2 in) long, line- to threat-shaped with short densely matted woolly hairs pressed to its surface. The upper part (or limbs), which enclosed the pollen presenter in the bud, are 11⁄2 mm (0.06 in) long, elliptic in shape with an almost pointy tip and covered with densely matted woolly hairs. The four anthers are each almost directly attached to the limbs and about 1.4 mm (0.055 in) long. From the center of each flower emerges a style of 5–7 mm (0.20–0.28 in) long, topped by a slightly pointy, almost hoof-shaped stigma of 3⁄4 mm (0.028 in) long. The ovary is covered with fine soft short hairs. The inverted egg-shaped fruit is about 4 mm (0.16 in) long has short felty hairs in the upper half.
