Protea revoluta R.Br.

Prostrate shrublet with horizontally sprawling subterranean stems; forming clumps or tufts up to 2 m in diam., 20 cm in height. Stems 5-15 mm in diam., glabrous, much branched, spreading horizontally; regeneration taking place from the subterranean branch system, after burning. Leaves linear 15-25 cm long, 2-3 mm wide, margins revolute, petiolar region terete, apices cuspidate; secund, close set, glaucous, flushed with pinkish carmine when young. Inflorescence globose in bud, opening to broadly crateriform, 4-6 cm in diam. Receptacle conic-acute, 1.5-2 cm wide, 1 cm high. Involucral bracts greenish yellow, occasionally flushed with carmine, 5-6 seriate; outer series ovate-acute, 5-8 mm wide, 7-10 mm long, thin textured and papyraceous, glabrous but margins ciliate; inner series oblong-spathulate, 3-3.5 cm long, apices concave and rounded, margins hyaline, occasionally ciliate. Perianth 2.5-3 cm long, adaxially curved; tube region 1 cm long inflated distally, prominently quadrangular, winged, glabrous, sharply constricted at junction with perianth claws; claws slender, hyaline, pubescent along inner margin; limbs 5 mm long, linear, apices sharply acute, villous to lanate. Style adaxially arcuate, 3 cm long, compressed vertically. Pollen presenter linear filiform, simple, 3-4 mm long, scarcely differentiated from style. Hypogynous scales oblong, 2 mm long obtuse. Ovary 2-3 mm long obconic, covered with long, straight tawny trichomes. Flowering commences in late November, with December the peak of the season. However, odd flower-heads continue to open well into January.
