Abstract

The Middle Stone Age deposits at Sibudu contain sedge (Cyperaceae) nutlets, which previously have been interpreted as indirect evidence of bedding. Scanning electron microscopy was used to identify the sedge nutlets through comparison of archaeological specimens with modern analogues. The presence of nutlets of Cladium mariscus (L.) Pohl subsp. jamaicense (Crantz) Kuk, a 1-3 m tall sedge with long scabrid leaves, was unexpected and challenges the bedding hypothesis because of the minute sharp hairs along the midrib and margins of the leaf blades. Nevertheless, we argue for the use ofCladium as bedding material, possibly as the foundation on which softer material was laid. It is possible that the Cladium nutlets and rhizomes may have been eaten and that the plant was also used as kindling or fuel.
