Abstract
S. subsecundum Nees and S. auriculatum Schimp. are distinct species which can always be separated when well grown. Poorly grown S. auriculatum can resemble S. subsecundum, but can almost invariably be distinguished by careful selection of the larger stem leaves in any gathering. When the size of both stem and branch leaves is taken into account, confusion can hardly ever arise, even with depauperate forms. S. inundatum Russ. is not specifically distinct from S. auriculatum, and is recombined as S. auricula tum Schimp. var. inundatum (Russ.) M. O. Hill.
