Taxonomy.
"Cyclocodon lancifolius" was scientifically described by William Roxburgh as "Campanula lancifolia" in 1824. In 1872 it was moved by Wilhelm Sulpiz Kurz to "Cyclocodon".

In the 1990s evidence began to emerge that "Cyclocodon" should be reinstated. "Cyclocodon lancifolius" is listed as the accepted name in Plants of the World Online and World Flora Online.
