Sorocephalus capitatus Rourke
VU Indigenous Endemic

Morphological description

An erect well branched shrub with a strong main stem, 0-75-1 m tall, branching at 0-25 m. Stems slender, covered with closely clasping densely imbricate leaves. Leaves 6-12 mm long, narrowly lanceolate, slightly 3 ridged on the upper surface, otherwise flattened, sparsely sericeous at first becoming scabrous glabrescent later. Inflorescence terminal, single or with up to three inflorescences terminating a flowering shoot, globose, 2-3 cm in diam. Involucres 8-9 flowered, densely clustered together. Perianth limbs of the innermost flowers of the involucre glabrous, perianth limbs of the outermost flowers woolly. Bracts narrowly lanceolate to broadly ovate, 9 mm long, 1-5 mm broad. Outer surface usually glabrous, occasionally sparsely sericeous, margins densely ciliate. Bracteoles lanceolate to narrowly ovate, glabrous. Perianth 12 mm long. Perianth limbs narrowly ovate, woolly to glabrous. Perianth claws linear, densely woolly. Perianth tube 5 mm long, sericeous above, becoming glabrous and slightly inflated at the base. Anthers sessile, elliptic, apical boss black, pointed. Style filiform, 9 mm long. Pollen presenter capitate, with a terminal stigmatic papilla. Ovary ellipsoid, sericeous, 1 mm. long. Hypogynous scales linear subulate, 3 mm long, arching up over the ovary. Fruits glabrous, cylindrical, narrowly emarginate at the base, 6 mm long, 2 mm broad. From: Rourke, JP. 1969.

Slender, single-stemmed shrub to 1 m. Leaves linear, adpressed, glabrescent, 6-12 mm long, margins scabrid. Flower heads in globose clusters, 20-30 mm diam., pink or cream-coloured, inner florets with perianth tips glabrous. From: Manning, JC; Goldblatt, P. 2012. Proteaceae.

Diagnostic description

S. capitatus is easily distinguished from the species with semi-terete leaves by the markedly capitate pollen presenter. The very long (3 mm) incurved hypogynous scales are also distinctive. A unique feature of this species is the variation in the pubescence of the perianth limbs. In each involucre the perianth limbs of the outermost flowers are lanate, while those of the innermost flowers are glabrous. From: Rourke, JP. 1969. Taxonomic studies on Sorocephalus R.Br. and Spatalla Salisb. J. S. African Bot.: 1-124. [CC BY]

Habitat

S. capitatus grows in small colonies on sandy patches between weathered outcrops of Table Mountain sandstone. The associated vegetation consists mainly of low tufted Restionaceae. A moderate winter rainfall of 20-25' p.a. is experienced with occasional snowfalls during a severe winter. The flowering period is rather long, from October to February, and is due to the development of lateral inflorescences which arise below the main terminal inflorescence when it has faded.

Distribution

Only two isolated populations of this species are known, one on the Piketberg, the other in the mountains at Onderbos Kloof in the Cold Bokkeveld. From: Rourke, JP. 1969. Taxonomic studies on Sorocephalus R.Br. and Spatalla Salisb. J. S. African Bot.: 1-124. [CC BY]
