An erect well branched shrub to 0.75 m with a single main stem branching at 20 cm. Branches erect, terete, puberulus, covered with ascending silvery leaves. Leaves acicular terete, mucronate, slightly spreading, ascending to incurved, 10-15 mm long, very densely sericeous, silvery. Inflorescence terminal, sessile, or with up to 4 lateral inflorescences arising at the apex of a shoot; 2-3 cm long, 1.5 cm in diam. Bracts lanceolate acute, 6 mm long, densely sericeous, silvery. Involucres 3 flowered, pedicellate, pedicel 2-3 mm long. Bracteoles free, broadly ovate acute, 4 mm long, 2 mm broad, very densely sericeous, margins ciliate. Median anticous bracteole subtends a short reduced shoot. Perianth 8 mm long, strongly curved forward in bud, perianth segments unequal. Posticous segment erect and galeate, larger than the three anticous segments. Perianth limbs elliptic, 1 mm long, lanate. Posticous perianth limb strongly galeate, larger than the three anticous limbs. Perianth claws thickly villous, the three anticous claws becoming coiled on opening. Perianth tube 1.5 mm long, villous, slightly quadrangular. Style straight, 6 mm long. Pollen presenter a dark black obliquely obovate cochleariform disc. Ovary ovoid, 1 mm long, tomentose.

Diagnostic description

This species is distinguished from S. incurva by the permanent densely sericeous silvery pubescence of the leaves, the obovate cochleariform pollen presenter and the distinctly galeate posticous perianth limb. From: Rourke, JP. 1969. Taxonomic studies on Sorocephalus R.Br. and Spatalla Salisb. J. S. African Bot.: 1-124. [CC BY]

Habitat

The plants occur as scattered isolated individuals on level sandy patches between large Table Mountain sandstone boulders on hot, dry north facing slopes at an altitude of 1067-1219 m They have always been found growing in close association with Leucadendron nervosum, a rare species which is also endemic to Jonas Kop.

Distribution

S. argentea has a very limited distribution and is confined to the north slopes of Jonas Kop (also known by the names Wildepaardeberg, Omklaar, and Bosjeveld mountains). From: Rourke, JP. 1969. Taxonomic studies on Sorocephalus R.Br. and Spatalla Salisb. J. S. African Bot.: 1-124. [CC BY]
