Taxonomic notes: As proposed by Mitchell in Jessop (1981) Flora of central Australia S. cryphiopetala and S. phaeotricha are treated as likely to be synonymous and the earlier name is therefore adopted here. Specimens from the Everard Range (NW) with a lighter coloured finer tomentum and only 1-3 mericarps developing in fruit may represent a distinct taxon.
