We have seen only one specimen of this apparently distinct species—in the Bolus 
Herbarium, Capetown. It extends the distribution of the group Tetraptérae, formerly 
only known by the solitary species (S. tetraptera) from the Nile districts, through the 
Zambezi Basin (S. Kirkw and S. Rogersw) into the sub-tropical Transvaal.
