Question: how is Lewisia and Heliconia connected?

Context paragraphs:
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.

Lewisia leeana: Lewisia leeana (orth.var.  "L. leana") is a species of flowering plant in the Montiaceae family known by the common name quill-leaf lewisia.  It is native to California and Oregon, where it grows in the mountains of the Sierra Nevada and Klamath Ranges.  This is a perennial herb growing from narrow, woody taproot connected to one or more caudices.  It produces a basal rosette of many fleshy flat to cylindrical blunt-tipped leaves up to 4 centimeters long.  The inflorescence bears many flowers on erect, branching stems up to about 24 centimeters tall.  Each flower has 5 to 8 white, pink, or purplish petals each about half a centimeter long.

Heliconia: Heliconia, derived from the Greek word "helikonios", is a genus of flowering plants in the family Heliconiaceae.  Most of the ca 194 known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku.  Many species of "Heliconia" are found in rainforests or tropical wet forests of these regions.  Several species are widely cultivated as ornamentals, and a few are naturalized in Florida, Gambia and Thailand.  Common names for the genus include lobster-claws, toucan peak, wild plantains or false bird-of-paradise.  The last term refers to their close similarity to the bird-of-paradise flowers ("Strelitzia").  Collectively, these plants are also simply referred to as "heliconias".
