Description
Robert A. Cannings gives a cladistic overview of some defined Lasiopogon species groups, and provides a detailed taxonomic and phylogenetic analysis of the seven groups and 29 species in the opaculus section, comprising about a quarter of the genus. He then describes 14 new species in this section and redescribes the others. He also offers a biogeographic hypothesis of the history of Lasiopogon, suggesting that the genus may have originated in Laurasia as early as the late Jurassic period.
