Leucospermum arenarium Rycroft

A low spreading shrub to 0.75 m in height, 1.0-1.5 m in diam., with a single main stem at base; trunk, 4.0-5.0 cm in diam., bark smooth, grey. Flowering stems lax, drooping, or arching onto the ground, sometimes trailing. Leaves secund on flowering stems; narrowly oblong-linear, 6.0-8.0 cm long, 0.7 cm wide, rather loosely spaced, usually entire, rarely with 2 or 3 teeth, slightly attenuated and twisted towards base; covered with a dense grey indumentum of fine crisped hairs. Inflorescences depressed globose, 5.0-7.0 cm in diam.; pedunculate to subsessile, usually solitary, occasionally in pairs; peduncle when present 1.0-4.0 cm long. Involucral receptacle broadly conic-depressed, 1.5 cm long, 1.5 cm broad. Involucral bracts ovate acuminate, 8.0-0.0 mm long, 6.0 mm broad, membranous, minutely puberulous to glabrescent; apices somewhat recurved, margins minutely ciliate; bracts reddish-carmine when fresh. Bracteoles oblanceolate, abruptly acuminate, 2.0 mm long, 4.0 mm broad, cartilaginous; base very densely lanate, the apex acuminate, shortly sericeous. Perianth 2.0-2.5 cm long, very strongly adaxially curved in bud. Perianth tube 7.0 mm long, cylindric, glabrous proximally becoming pilose distally. Perianth claws puberulous to sparsely villous, the median adaxial claw glabrous; the adaxial claws becoming strongly coiled in a sigmoid manner. Perianth limbs linear to narrowly lanceolate, acute, 4.0 mm long, villous. Anthers sessile, narrowly lanceolate linear, acute, apical boss, pointed, yellow. Style 3.0-3.5 cm long, strongly incurved, tapering towards the apex, pale ivory to yellowish green. Pollen presenter 2.5 mm long, 0.5 mm in diam., cylindric acute, greenish towards apex; stigmatic groove terminal. Hypogynous scales subulate, hyaline. Although all the collections of flowering material that are known were made in August, it is clear from the faded inflorescences and new buds on living plants that flowering commences in July and probably continues until October.
