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.
Helicene In organic chemistry, helicenes are ortho-condensed polycyclic aromatic compounds in which benzene rings or other aromatics are angularly annulated to give helically-shaped molecules. The chemistry of helicenes has attracted continuing attention because of their unique structural, spectral, and optical features.
