Question: Which is a species in southern Africa, Clytostoma or Zantedeschia aethiopica?

full_context: Document 1: Zantedeschia albomaculata: Zantedeschia albomaculata, commonly known as the spotted calla lily or white spotted arum, is a species of flowering plants in the genus "Zantedeschia".
Document 2: Calloideae: Calloideae is a monotypic subfamily of flowering plants in the Araceae family. The single genus in the family is Calla, although in the past under Engler's description of Araceae it included four genera, namely Lysichiton, Symplocarpus, Orontium, and Calla. The subfamily was subsequently made monotypic and given a single tribe, Callea. Species in Calloideae are often found in marshy habitats in the northern hemisphere. Trichosclereids are not found in the flowers.
Document 3: Campsis × tagliabuana: Campsis" × "tagliabuana (Madame Galen) is a mid-19th-century hybrid between "Campsis radicans" (American trumpet vine) and "Campsis grandiflora" (Chinese trumpet vine). It produces trumpet-shaped, orange to red flowers up to 3 in long that appear in loose clusters of 6 to 12. It is a woody, clinging, perennial vine that attaches itself to structures and climbs vigorously with aerial roots like those of ivy. It bears dark-green deciduous leaves, 8 - long. Its flowers are very attractive to bees, butterflies and birds. Like its parents it is hardy but in cooler temperate regions requires the shelter of a sunny wall to produce its spectacular flowers in abundance.
Document 4: Campsis radicans: Campsis radicans (trumpet vine or trumpet creeper, also known in North America as cow itch vine or hummingbird vine), is a species of flowering plant of the family Bignoniaceae, native to the eastern United States and naturalized in parts of the western United States as well as in Ontario, parts of Europe, and scattered locations in Latin America. Growing to 10 m , it is a vigorous, deciduous woody vine, notable for its showy trumpet-shaped flowers. It inhabits woodlands and riverbanks, and is also a popular garden subject.
Document 5: Zamioculcas: Zamioculcas (common name "Zanzibar Gem", "Zuzu Plant" or Emerald Palm) is a genus of flowering plant in the family Araceae, containing the single species Zamioculcas zamiifolia. It is a tropical perennial plant native to eastern Africa, from Kenya south to northeastern South Africa. Dutch nurseries started wide-scale commercial propagation of the plant around 1996.
Document 6: Clerodendrum splendens: Clerodendrum splendens (glory tree, flaming glorybower) is a species of flowering plant in the genus "Clerodendrum" of the family Lamiaceae, native to tropical Western Africa. It is a twining evergreen climber, growing to 3 m or more, with panicles of brilliant scarlet flowers in summer. With a minimum temperature of 10 C , it requires the protection of glass during the winter months in most temperate regions.
Document 7: Lophospermum: Lophospermum is a genus of herbaceous perennial climbers or scramblers, native to mountainous regions of Mexico and Guatemala. Those that climb use twining leaf stalks. Their flowers are tubular, in shades of red, violet and purple, the larger flowers being pollinated by hummingbirds. Now placed in the greatly expanded family Plantaginaceae, the genus was traditionally placed in the Scrophulariaceae. The close relationship with some other genera, particularly "Maurandya" and "Rhodochiton", has led to confusion over the names of some species.
Document 8: Campsis: Campsis (trumpet creeper, trumpet vine) is a genus of flowering plants in the family Bignoniaceae, native to woodland in China and North America. It consists of two species, both of which are vigorous deciduous perennial climbers, clinging by aerial roots, and producing large trumpet-shaped flowers in the summer. They are hardy but require the shelter of a warm wall in full sun.
Document 9: Zantedeschia aethiopica: Zantedeschia aethiopica (known as calla lily and arum lily) is a species in the family Araceae, native to southern Africa in Lesotho, South Africa, and Swaziland.
Document 10: Chlidanthus: Chlidanthus is a genus that consists of 10 species of tender bulbs from tropical South America, mostly natives to the Andes. The botanical name comes from the Greek, meaning "delicate flower". The plants have large spherical bulbs with gray-green, strap-shaped leaves 30cm long arising from the base. In late spring to early summer, clusters of 3-4 large, strong citrus-scented fragrant, funnel-shaped flowers 10-13cm long held terminally on stalks 25cm high, colored in yellow, pink or red.
Document 11: Zantedeschia: Zantedeschia is a genus of 8 species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The genus has been introduced on all continents except Antarctica. Common names include arum lily for "Z. aethiopica" and calla and calla lily for "Z. elliottiana" and "Z. rehmannii", although members of the genus are neither true lilies of Liliaceae, true "Arums", or true "Callas" (related genera in Araceae). They are also often confused with "Anthurium". The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.
Document 12: Clytostoma: Clytostoma was a genus of woody-stemmed vines from tropical America, native to Argentina and the southern part of Brazil. It is now considered a synonym of "Bignonia". The botanical name comes from the Greek, "klytos" means splendid or beauteous, and "stoma" means mouth; alluding to the beautiful flowers. It is closely related to "Bignonia", from which it differs chiefly in its simple slender tendrils, the short disk, and that it has a habit of clambering over adjacent foliage using tendrils to hang on tight. The bright glossy green leaves are lobed and divided with 2 leaflets, about 3in (7.6cm) long and 1.5in (3.8cm) wide. They are arranged opposite in pairs and tendrils arise at the ends of the leaf stalks. In late spring, the spectacular 1.5in (3.8cm) trumpet flowers are borne terminally or along the branches. The flowers are pale lavender and delicately detailed with dark violet and purple veins. Flowers are followed by large prickly seed pods. This evergreen ornamental plant easily reaches to 16 feet and is a carefree grower. It has only recently been moved out of the genus "Pandorea".
Document 13: Cydista: Cydista is a genus that consists of more than twenty species of lowland, showy, evergreen, ornamental shrubs and woody vines, ranging from central and southern Mexico to Paraguay and eastern Brazil. The genus is characterized by the lack of a nectariferous disk and is associated with the multiple-bang flowering syndrome. All species are lianas with clusters of funnelform flowers, bloomig twice a year in spring and fall. The flowers start of purple and change to a lighter shade of lavender with age, then fading to almost white, followed by linear oblong fruits and winged seeds. The plants are multi-stemmed with opposite, oval, glossy, dark-green leaves and 2 leaflets, and climb by tendrils arise from the leaf axils. Leaves smell like garlic when crushed.
Document 14: Clivia miniata: Clivia miniata (Natal lily, bush lily, Kaffir lily) is a species of flowering plant in the genus "Clivia" of the family Amaryllidaceae, native, growing in woodland habitats in South Africa (Eastern Cape, Mpumalanga and KwaZulu-Natal provinces) as well as in Swaziland. Given suitable conditions it grows into large clumps and is surprisingly water wise. It is also reportedly naturalized in Mexico. It is a popular plant for shady areas and is commonly seen growing in older established suburbs in most Australian states. It is also popular in New Zealand, Japan, China and southern parts of the USA , particularly California.
Document 15: Arum: Arum is a genus of flowering plants in the family Araceae, native to Europe, northern Africa, and western and central Asia, with the highest species diversity in the Mediterranean region. Frequently called "arum lilies", they are not closely related to the true lilies "Lilium". Plants in closely related "Zantedeschia" are also called "arum lilies".
