Question: Which of these is named after a character from Shakespeare's "The Tempest" Nerium or Calibanus ?
Context: The Tempest, also known as The Tempest (Prospero and Miranda), or simply Prospero and Miranda, is an outdoor bronze sculpture depicting Prospero from William Shakespeare's "The Tempest" by Milton Hebald, installed outside Delacorte Theater in Manhattan's Central Park, in the U.S. state of New York.  The work, which was gifted by George T. Delacorte, Jr. and unveiled in 1966, is a companion piece to "Romeo and Juliet" (1977). Une Tempête ("A tempest") is a 1969 play by Aimé Césaire.  It is an adaptation of Shakespeare's "The Tempest" from a postcolonial perspective.  The play was first performed at the Festival d'Hammamet in Tunisia under the direction of Jean-Marie Serreau.  It later played in Avignon and Paris.  Césaire uses all of the characters from Shakespeare's version, but he specifies that Prospero is a white master, while Ariel is a mulatto and Caliban is a black slave.  These characters are the focus of the play as Césaire foregrounds issues of race, power, and decolonization. The Tempest is a play by William Shakespeare, believed to have been written in 1610–11, and thought by many critics to be the last play that Shakespeare wrote alone.  It is set on a remote island, where the sorcerer Prospero, rightful Duke of Milan, plots to restore his daughter Miranda to her rightful place using illusion and skillful manipulation.  He conjures up a storm, the eponymous tempest, to cause his usurping brother Antonio and the complicit King Alonso of Naples to believe they are shipwrecked and marooned on the island.  There, his machinations bring about the revelation of Antonio's lowly nature, the redemption of the King, and the marriage of Miranda to Alonso's son, Ferdinand. Calibanus is a genus of two species of flowering plants, both evergreen succulents from dry areas of northeastern Mexico.  The APG III classification system places it in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae. )  It was formerly included in the Agavaceae (now Agavoideae) but is now separated from them, for it is polycarpic and dioecious.  Its name refers to the monster Caliban, an antagonist in Shakespeare's "The Tempest". The Sea and the Mirror: A Commentary on Shakespeare's "The Tempest", is a long poem by W.H. Auden, written 1942–44, and first published in 1944.  Auden regarded the work as “my "Ars Poetica," in the same way I believe "The Tempest" to have been Shakespeare’s.” Un re in ascolto ("A King Listens") is an opera by Luciano Berio, who also wrote the Italian libretto.  It is based on a short story, Under the Jaguar Sun by Italo Calvino, but incorporates excerpts from Friedrich Einsiedel's 1778 libretto (as reworked by Friedrich Wilhelm Gotter between 1790 and 1791) for an opera based on Shakespeare's "The Tempest".  This became "Die Geisterinsel" in 1798, set to music written by Friedrich Fleischmann.  In addition, W. H. Auden's "The Sea and the Mirror: A Commentary on Shakespeare's The Tempest" was a source. Beach Blanket Tempest is an Australian musical with book and lyrics by Dennis Watkins and music by Chris Harriott, loosely based on Shakespeare's "The Tempest". Nerium oleander is a shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts.  It is the only species currently classified in the genus Nerium.  It is most commonly known as nerium or oleander, from its superficial resemblance to the unrelated olive "Olea".  It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested.  The ancient city of Volubilis in Morocco may have taken its name from the Berber name "oualilt" for the flower.  Oleander is one of the most poisonous commonly grown garden plants. The Journey to Melonia (Swedish: Resan till Melonia ) is a 1989 Swedish-Norwegian animated fantasy adventure film directed by Per Åhlin, very loosely based on William Shakespeare's "The Tempest".  It was Per Åhlin's first fully animated feature film, since his earlier films "Out of an Old Man's Head" and "Dunderklumpen! " had both used a mix of animation and live action.  The full English title is "The Journey to Melonia: Fantasies of Shakespeare's 'The Tempest"'. Return to the Forbidden Planet is a Jukebox musical by playwright Bob Carlton based on Shakespeare's "The Tempest" and the 1956 science fiction film "Forbidden Planet" (which itself drew its plot loosely from "The Tempest").  It was billed as Shakespeare's forgotten rock and roll masterpiece.
