Question: What genus of plants is native to southwestern Asia, Cassiope or Calendula?

full_context: Document 1: Cypripedium: Cypripedium is a genus of 58 species and nothospecies of hardy orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae). They are widespread across much of the Northern Hemisphere, including most of Europe (one species), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids or lady's slipper orchids; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe. An abbreviation used in trade journals is "Cyp." The word ""Cypripedium"" is derived from the Late Latin: "Cypris", from Ancient Greek: Κυπρις  "(Kypris)" , an early reference in Greek myth to Aphrodite, and Greek: "pedilon", meaning "sandal".
Document 2: Calendula arvensis: Calendula arvensis is a species of flowering plant in the daisy family known by the common name field marigold. It is native to central and southern Europe, and it is known across the globe as an introduced species.
Document 3: Cassiope: Cassiope is a genus of 9-12 small shrubby species in the family Ericaceae. They are native to the Arctic and north temperate montane regions. The genus is named after Cassiopeia of Greek mythology. Common names, shared with several other similar related genera, include heather and heath. They have scale-like leaves lying against the stems, and produce solitary bell-shaped flowers in late spring. Though hardy, flowers can be damaged by late frosts.
Document 4: Ericaceae: The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acid and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well-known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers ("Erica", "Cassiope", "Daboecia", and "Calluna" for example).
Document 5: Calendula maritima: Calendula maritima, known as the sea marigold and trailing calendula, is a very rare species from the family of Asteraceae. Some scientists regarded it as "Calendula suffruticosa" subspecies "maritima".

Document 7: Chrysanthemum: Chrysanthemums ( ), sometimes called mums or chrysanths, are flowering plants of the genus Chrysanthemum in the family Asteraceae. They are native to Asia and northeastern Europe. Most species originate from East Asia and the center of diversity is in China. There are countless horticultural varieties and cultivars.
Document 8: Anthemis: Anthemis is a genus of aromatic flowering plants in the family Asteraceae, closely related to "Chamaemelum", and like that genus, known by the common name chamomile; some species are also called dog-fennel or mayweed. "Anthemis" are native to the Mediterranean region and southwest Asia east to Iran. A number of species have also become naturalized in the United Kingdom and other parts of the world.
Document 9: Erica: Erica is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus "Calluna" was formerly included in "Erica" – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. "Erica" is sometimes referred to as "winter (or spring) heather" to distinguish it from "Calluna" "summer (or autumn) heather".
Document 10: Calendula officinalis: Calendula officinalis (pot marigold, ruddles, common marigold or Scotch marigold) is a plant in the genus "Calendula" of the family Asteraceae. It is probably native to southern Europe, though its long history of cultivation makes its precise origin unknown, and it may possibly be of garden origin. It is also widely naturalised further north in Europe (north to southern England) and elsewhere in warm temperate regions of the world.
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: Caulanthus: Caulanthus is a genus of plants in the mustard family. Plants of this genus may be known as jewelflowers. They are also often referred to as wild cabbage, although this common name usually refers to wild variants of "Brassica oleraceae", the cabbage plant. Jewelflowers are native to the southwestern United States and northern Mexico, where they are often found in warm, arid regions. Many species have an enlarged, erect stem rising from a basal rosette of leaves. Flowers arise directly from the surface of the stem; many species have colorful, bell-shaped flowers. The best-known of the fourteen species is probably the desert candle.
Document 13: Chamaemelum: Chamaemelum is a small genus of plants in the daisy family commonly known as chamomiles or dogfennels. Perhaps the best-known species is Roman chamomile, "Chamaemelum nobile". These are annual or perennial herbs, rarely exceeding half a meter in height and usually bearing solitary white daisylike flowers with yellow centers. They are native to Europe but most species can be found scattered in other continents where they have been introduced.
Document 14: Calendula: Calendula ( ), is a genus of about 15–20 species of annual and perennial herbaceous plants in the daisy family Asteraceae that are often known as marigolds. They are native to southwestern Asia, western Europe, Macaronesia, and the Mediterranean. Other plants are also known as marigolds, such as corn marigold, desert marigold, marsh marigold, and plants of the genus "Tagetes".
Document 15: Phygelius: Phygelius, common names Cape fuchsia or Cape figwort, is a genus of flowering plants in the Scrophulariaceae family, native to wet slopes and banks in southern Africa. They are evergreen shrubs often treated as perennials in colder climates. They bear many pendent tubular flowers over a long period in summer, in shades of white, yellow and red. The vague similarity of the blooms to fuchsias has led to the common name Cape fuchsia, though they are not closely related.
