A low, prostrate shrub, forming dense tufts, 0.5-1.5 m in diam. and to 0.5 m in height. Stems and branch system tightly interlocking, spreading horizontally over substratum. Leaves clustered at ends of flowering shoots, 20-45 cm long, glabrous at maturity; petiolate, petiole, 10-20 cm long, semiterete, carmine; lamina conduplicate, elliptic to broadly elliptic or oblanceolate, 4-8 cm wide, hard and coriaceous; apex subacute to obtuse, occasionally minutely mucronate; margins horny. Inflorescences terminal, sessile, broadly turbinate, later cyathiform, 8-12 cm in diam., 10-12 cm long, surrounded at base by loose, brown, papyraceous, lanceolate-acuminate involucral leaves, 2-3 cm long, 0.5-1 cm broad. Receptacle convex, 2.5-3.5 cm in diam. Involucral bracts 6-8 seriate, the innermost series very narrowly linear-lanceolate, acuminate, 4-4.5 cm long, 4-6 mm wide, inner surface glabrous and brilliant crimson, outer surface covered with a dense, white lanate indumentum; outer series ovate-acute, 2-3.5 cm long, 1.5-2 cm broad, outer surface glabrous and crimson at base, but covered with a very dense, white, lanate indumentum on upper part. Perianth 5.5-6.5 cm long, slightly adaxially curved; tube glabrous, quadrangular; claws glabrous on outer surface but inner surface and margins puberulous; limbs, 1.5-1.7 cm long, linear, thickly villous to lanate, apices acuminate. Anthers subsessile, 8 mm long, apical boss acuminate. Style slightly adaxially arcuate, 5.5-6 cm long, flattened longitudinally above ovary, tapering sub-terminally. Pollen presenter linear, acute, 1 cm long. Ovary narrowly obovoid, 5 mm long, covered with long, straight, white hairs. Hypogynous scales very broadly ovate, 1.5 mm long. The flowering season is brief but well defined, commencing in mid-January and continuing until the end of February. From: Rourke, JP. 1980. The proteas of southern Africa. Purnell, Cape Town.

Dwarf shrub, 0.4-0.5 m high, prostrate, branches creeping. Leaves petiolate, elliptic to oblanceolate, folded lengthwise, 200-450 x 40-80 mm, coriaceous, margins horny. Flower head deeply cup-shaped, 100-120 x 80-120 mm, with loose, brown lanceolate-acuminate basal bracts. Involucral bracts 6-8-seriate; outer series ovate-acute, 20-35 x 5-20 mm, outer surface glabrous, crimson at base, very dense, white, woolly indumentum on upper part; inner series linear-lanceolate, acuminate, 40-45 x 4-6 mm, inner surface glabrous, crimson, outer surface with dense, white, woolly indumentum. Flowers: perianth white, 55-65 mm long, slightly curved, tube 38-40 mm long, glabrous; style 55-60 mm long, white; pollen presenter 10 mm long, linear. Flowering time Jan., Feb.

Prostrate, mat-forming shrublet to 1.5 m diam. Leaves petiolate, oblanceolate, rough. Flower heads cup-shaped, 80-120 mm diam., involucral bracts acuminate, red, densely white-woolly outside, style 55-60 mm long. From: Manning, JC; Goldblatt, P. 2012. Proteaceae.

Although in general aspect P. pruinosa resembles P. cryophila (endemic to the Cedarberg), the inflorescences are considerably smaller. Moreover the involucral bracts are ovate acute and are only lanate towards the apex, being glabrous and carmine at the base, while in P. cryophila they are narrowly acuminate and entirely woolly on their outer surfaces.

A strictly high altitude species, occurring at elevations between 1800 and 2100 metres, P. pruinosa seems to favour the very uppermost ridges and rocky crests near the summits of the great peaks it inhabits. Equally at home on hot north-facing slopes as well as in cooler habitats of southerly aspect, it is edaphically adaptable, growing on deep peaty soils or in coarse Table Mountain Sandstone rubble. Never common in any one locality, the populations are sparse and sporadically distributed, rarely consisting of more than two dozen plants, mostly occurring as rather isolated specimens.

Until quite recently, P. pruinosa was thought to be restricted to a very short stretch of the Klein Swartberg, between Towerkop and Hoekoe, in the vicinity of Ladismith. Sightings have subsequently been reported from more easterly localities on the Swartberg Range with a definite record from a peak near Blesberg, a few kilometres east of Meiring's Poort. Thus Towerkop and Blesberg are presently the most westerly and easterly limits of the species' range, while further records from the central Swartberg can be expected in the future.
