Leucospermum reflexum is a large rounded shrub that is assigned to the family Proteaceae. It grows from a single trunk and its branches are covered in smooth grey bark. It has small elliptic to inverted lance-shaped greyish leaves of only 2–5½ cm (0.8–2.2 in) long. The heads consist of mostly dark orange (rarely pale yellow) 4-merous flowers, from which long, identically colored styles emerge, which are directed straight down during flowering. It is called rocket pincushion or skyrocket leucospermum in English and perdekop (horse head) in Afrikaans. It flowers from the end of August to December. It is an endemic species that can only be found in the southwest of South Africa.

The rocket pincushion is a large rounded shrub of up to 4 m (13 ft) in diameter, which grows from a single trunk at its base. The branches are covered in smooth grey bark. The flowering stems are stiffly upright and 3–6 mm (0.12–0.24 in) thick. These are grey due to a dense covering of fine twisted hairs pressed to the surface and some long straight erect hairs. The alternately set leaves are directed upwards at an angle with the branch, elliptic to inverted lance-shaped and only 2–5½ cm (0.8–2.2 in) long, ½–1¼ cm (0.2–0.5 in) wide, and also have a dense covering of fine twisted hairs pressed to the surface. The tip of the leaf mostly has two or three teeth, but is sometimes entire.[3]

The flower heads are set individually near the end of the branches, globe to egg-shaped when young, 8–10 cm (3.1–3.9 in) in diameter on a stalk of 3–6 cm (1.2–2.4 in) long. The common base of the flowers in the same head is narrowly cylinder-shaped, 2–3½ cm (0.8–1.4 in) long and ½–¾ cm wide (0.2–0.3 in) thick. The bracts subtending the flowerhead are narrowly triangular with a pointy tip, 1–1¼ cm (0.4–0.5 in) long and 4 mm (0.16 in) wide at its foot, rubbery in consistency, with a poor tuft of long hairs at its tip and a row of hairs along its margin (like an eyelash). The bract subtending the individual flower tightly embrace the perianth at its foot, are about 1 cm (0.4 in) long and 6–8 mm wide at its base with a pointy tip that may curve out, with thick woolly hairs at the base and thinner set with long straight hairs near the top.[3]

The perianth itself is 4–5 cm (1.6–2 in) long, mostly crimson to deep orange, very rarely pale yellow. The lowest part that remains fused after the flower opens called tube is about 1 cm (0.4 in) long, hairless and narrow at the foot and finely powdery and wider nearer to the top. The middle part that is split when the flower has opened called claws are uniformly covered in soft long hairs, strongly bending as soon as the flower opens and forcing the style downward. The wider, terminal parts of the perianth called limbs, that cover the pollen presenter in the bud, are very narrowly lance-shaped to linear, 5–6 mm (0.20–0.24 in) long and about 1½ mm (0.06 in) wide with pointy tips are also covered soft long hairs. Three of the claws remain attached over their full length forming a sheeth, the fourth free, but the limbs of all four attached and in-rolled. The anthers are directly attached to the perianth limbs, without filaments, awl-shaped, 4–5 mm (0.16–0.20 in) long. The style is 7–7½ cm (2.8–3.0 in) long; initially orange, later becoming deep crimson, yellow in the yellow form. The pollen presenter is as wide as the style, white, greenish yellow near the tip, cylindric to awl-shaped with a sharp tip, 5–6 mm (0.20–0.24 in) long, with an ever so slight knick at its base. The ovary, that is enclosed by the base of the perianth tube, is subtended by four awl-shaped, rubbery scales of about 3 mm (0.12 in) long.[3][6]

The subtribe Proteinae, to which the genus Leucospermum has been assigned, consistently has a basic chromosome number of twelve (2n=24).
