how is Lewisia and Heliconia connected?
Lewisia Lewisia is a plant genus, named for Meriwether Lewis who encountered the species in 1806. The native habitat of "Lewisia" species is north facing cliffs in the western part of North America. Local Native Americans ate the roots, which have also been used to treat sore throats.
Liliopsida Liliopsida (synonym: Liliatae) is a botanical name for the class containing the family Liliaceae (or Lily Family). It is considered synonymous (or nearly synonymous) with the name monocotyledon. Publication of the name is credited to Scopoli (in 1760): see author citation (botany). This name is formed by replacing the termination "-aceae" in the name Liliaceae by the termination "-opsida" (Art 16 of the ICBN).
