Introduced by Paetel (1873: 117) as a nomen nudum without description and attributed to Dunker this is an unavailable name (Art. 12.1 of the Code). Not made available subsequently by Paetel (1883: 178, 1889: 428). It remains an unavailable name. Hubendick (1946: 68) suggested it may be a misspelling of S. laciniosa .
