Amorphophallus is a large genus of some 200 tropical and subtropical tuberous herbaceous plants from the arum family (Araceae), native to Asia, Africa, Australia and various oceanic islands. The genus includes the Titan arum (A. titanum) of Indonesia, which has the largest inflorescence in the genus, and is known as the 'corpse flower' for the pungent odour it produces during its flowering period, which can take up to seven years of growth before it occurs. A few species are edible as "famine foods" after careful preparation to remove irritating chemicals.

Boquila is a genus of flowering plants in the family Lardizabalaceae, endemic to temperate forests of central and southern Chile and Argentina. It is monotypic, being represented by the single species Boquila trifoliolata, locally known as voqui blanco or pilpil in its native range, or the chameleon vine since a 2014 report on leaf mimicry. The species was first described in 1782 by Juan Ignacio Molina, and the genus was established in 1839 by Joseph Decaisne. B. trifoliolata forms non-parasitic vines that wind around host plants, using them for structure and protection. B. trifoliolata is
