Question: Which of these is named after a character from Shakespeare's "The Tempest" Nerium or Calibanus ?

full_context: Document 1: Calibanus: 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".
Document 2: Agave anomala: Agave anomala is a species of "Agave" in the family Asparagaceae. This species is found on Cuba and also on San Salvador Island in the Bahamas. Several other "Agave" including the ornamental species, "A. americana" (century plant) are present on San Salvador.
Document 3: Scadoxus multiflorus: Scadoxus multiflorus (formerly "Haemanthus multiflorus") is a bulbous plant native to most of sub-Saharan Africa from Senegal to Somalia to South Africa. It is also native to Arabian Peninsula (Saudi Arabia, Yemen, Oman) and to the Seychelles. It is naturalized in Mexico and in the Chagos Archipelago. It is grown as an ornamental plant for its brilliantly coloured flowers, either in containers or in the ground in where the climate is suitable. There are three recognized subspecies. Strongly toxic like other "Scadoxus" species, it has been used as a component of arrow poisons and fishing poisons, as well as in traditional medicine. Common names, some of which are used for other species, include blood lily, ball lily, blood flower, Katherine-wheel, oxtongue lily, poison root and powderpuff lily.
Document 4: Plumeria: Plumeria ( ) is a genus of flowering plants in the dogbane family, Apocynaceae. Most species are deciduous shrubs or small trees. The species variously are indigenous to Mexico, Polynesia, Central America, and the Caribbean, and as far south as Brazil, but are grown as cosmopolitan ornamentals in warm regions. Common names for plants in the genus vary widely according to region, variety, and whim, but frangipani or variations on that theme are the most common. Plumeria also is used directly as a common name, especially in horticultural circles.
Document 5: Moringa oleifera: Moringa oleifera is the most widely cultivated species of the genus "Moringa", which is the only genus in the family Moringaceae. English common names include: moringa, drumstick tree (from the appearance of the long, slender, triangular seed-pods), horseradish tree (from the taste of the roots, which resembles horseradish), ben oil tree, or benzoil tree (from the oil which is derived from the seeds). It is a fast-growing, drought-resistant tree, native to the southern foothills of the Himalayas in northwestern India, and widely cultivated in tropical and subtropical areas where its young seed pods and leaves are used as vegetables. It can also be used for water purification and hand washing, and is sometimes used in herbal medicine.
Document 6: Stephano (The Tempest): Stephano ( ) is a boisterous and often drunk butler of King Alonso in William Shakespeare's play, "The Tempest". He, Trinculo and Caliban plot against Prospero, the ruler of the island on which the play is set and the former Duke of Milan in Shakespeare's fictional universe. In the play, he wants to take over the island and marry Prospero's daughter, Miranda. Caliban believes Stephano to be a god because he gave him wine to drink which Caliban believes healed him.
Document 7: Gomphocarpus fruticosus: Gomphocarpus fruticosus (syn. "Asclepias fruticosa") is a species of milkweed native to South Africa. It is also common in New Zealand where it is the main host of the monarch butterfly. The plant's tissues contain sufficient cardenolides that consumption of significant quantities of the plant's leaves, stems, or fruit may lead to death in livestock and humans.
Document 8: Oleaceae: The Oleaceae are a family of flowering plants in the order Lamiales. It presently comprises 26 genera, one of which is recently extinct. The 25 extant genera include "Cartrema", which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The Oleaceae consist of shrubs, trees, and a few lianas. The flowers are often numerous and highly odoriferous. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members of the Oleaceae include olive, ash, jasmine, and several popular ornamental plants including privet, forsythia, fringetrees, and lilac.
Document 9: Hesperevax caulescens: Hesperevax caulescens is a small flowering plant in the daisy family. One common name for the plant is hogwallow starfish, as it is a somewhat flat, star-shaped plant which grows in mud. Another common name is dwarf dwarf-cudweed, as the three members of genus "Hesperevax" are known as dwarf-cudweeds and this species is smaller than the others. It may also be called involucrate evax, since its former Latin name was "Evax involucrata". This annual plant is a member of the vernal pool plant community in California, where it is possibly an endemic species, although its range might extend into Baja California. The hogwallow starfish radiates pale green spoon-shaped leaves in a basal rosette and extends a short erect stem. The flowers are less than two millimeters wide. This species grows along the outskirts of vernal pools in areas which have dried.
Document 10: Ruscus: Ruscus is a genus of six species of flowering plants, native to western and southern Europe (north to southern England), Macaronesia, northwest Africa, and southwestern Asia east to the Caucasus. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Like many lilioid monocots, it was formerly classified in the family Liliaceae.
Document 11: Calypso bulbosa: Calypso is a genus of orchids containing one species, Calypso bulbosa, known as the calypso orchid, fairy slipper or Venus's slipper. It is a perennial member of the orchid family found in undisturbed northern and montane forests. It has a small pink, purple, pinkish-purple, or red flower accented with a white lip, darker purple spottings, and yellow beard. The genus "Calypso" takes its name from the Greek signifying concealment, as they tend to favor sheltered areas on conifer forest floors. The specific epithet, "bulbosa", refers to the bulb-like corms.
Document 12: Datura: Datura is a genus of nine species of poisonous vespertine flowering plants belonging to the family Solanaceae. They are commonly known as daturas, but also known as devil's trumpets, not to be confused with angel's trumpets, its closely related genus "Brugmansia". They are also sometimes called moonflowers, jimsonweed, devil's weed, hell's bells, thorn-apple, and many more. Its precise and natural distribution is uncertain, owing to its extensive cultivation and naturalization throughout the temperate and tropical regions of the globe. Its distribution within the Americas and North Africa, however, is most likely restricted to the United States and Mexico and Southern Canada in North America, and Tunisia in Africa, where the highest species diversity occurs.
Document 13: Nerium: 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.
Document 14: Calibanus glassianus: Calibanus glassianus is a rare plant species known from the Mexican state of Guanajuato. It is an evergreen succulent with a swollen stem and red berries. It is one of only two known species in the genus Calibanus.
Document 15: Calibanus hookeri: One of only two species in its genus, Calibanus hookeri is a member of the Asparagaceae family native to Tamaulipas in Mexico, which can easily be mistaken in habitat for a boulder overgrown with grass tufts.
ground_truth: Calibanus
