Question: Argyreia and Dipcadi, have which mutual characteristic?

full_context: Document 1: Argyreia: Argyreia is a genus of plants in the Convolvulaceae family.
Document 2: Dipcadi: Dipcadi is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae). It is widely distributed, occurring in southern Europe, most of Africa and the Middle East through to the Indian subcontinent.
Document 3: Scilla: Scilla ( ; Squill) is a genus of about 50 to 80 bulb-forming perennial herbs in the family Asparagaceae, subfamily Scilloideae, native to woodlands, subalpine meadows, and seashores throughout Europe, Africa and the Middle-East. A few species are also naturalized in Australia, New Zealand and North America. Their flowers are usually blue, but white, pink, and purple types are known; most flower in early spring, but a few are autumn-flowering.
Document 4: Bulbophyllum: Bulbophyllum is the largest genus in the orchid family Orchidaceae. With more than 2,000 species, it is also one of the largest genera of flowering plants, exceeded only by "Astragalus". This genus is abbreviated in the trade journals as Bulb. It is found throughout most of the warmer parts of the world: Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans.
Document 5: Argophyllaceae: Argophyllaceae is a family of shrubs or small trees belonging to the order Asterales. The family includes two genera "Argophyllum" and "Corokia". Members of the family are native to eastern Australia, New Zealand, Lord Howe Island, New Caledonia, and Rapa Iti.
Document 6: Convolvulus cantabrica: Convolvulus cantabrica, common name Cantabrican morning glory or dwarf morning glory, is a herbaceous perennial plant belonging to the genus "Convolvulus" of the Convolvulaceae family.
Document 7: Amaryllis: Amaryllis ( ) is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae). It is a small genus of flowering bulbs, with two species. The better known of the two, "Amaryllis belladonna", is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley to Knysna. For many years there was confusion among botanists over the generic names "Amaryllis" and "Hippeastrum", one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus "Hippeastrum", widely sold in the winter months for their ability to bloom indoors. Plants of the genus "Amaryllis" are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name "lily" due to their flower shape and growth habit. However, they are only distantly related to the true lily, "Lilium".
Document 8: Dipsacus: Dipsacus is a genus of flowering plant in the family Caprifoliaceae. The members of this genus are known as teasel, teazel or teazle. The genus includes about 15 species of tall herbaceous biennial plants (rarely short-lived perennial plants) growing to 1 - tall. Dipsacus are native to Europe, Asia and northern Africa.
Document 9: 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 10: Ceropegia: Ceropegia is a genus of plants within the family Apocynaceae, native to Africa, southern Asia, and Australia. It was named by Carl Linnaeus, who first described this genus in volume 1 of his "Species plantarum", which appeared in 1753. Linnaeus thought that the flowers looked like a fountain of wax. From this the scientific name was derived: ‘"keros"’ meaning wax and ‘"pege"’ meaning fountain (Pooley, 1998). They have many common names including lantern flower, parasol flower, parachute flower, bushman’s pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine.
Document 11: Peperomia argyreia: Peperomia argyreia, the watermelon peperomia or watermelon begonia, is a species of plant in the Piperaceae family. Its native range is Bolivia, Brazil, Ecuador, and Venezuela.
Document 12: Eupatorieae: Eupatorieae is a tribe of over 2000 species of plants in the aster family. Most of the species are native to tropical, subtropical, and warm temperate areas of the Americas, but some are found elsewhere. Well-known members are "Stevia rebaudiana" (used as a sugar substitute), a number of medicinal plants ("Eupatorium"), and a variety of late summer to autumn blooming garden flowers, including "Ageratum" (flossflower) and "Conoclinium" (mistflower).
Document 13: Gynura aurantiaca: Gynura aurantiaca, called purple passion or velvet plant is a species of plants in the chrysanthemum family It is native to Southeast Asia but grown in many other places as a house plant. In warm regions, it is frequently grown in outdoor on patios and in gardens rather than inside buildings, and hence it has escaped into the wild in Africa, Australia, South America, Mesoamerica, Florida, and a few other places.
Document 14: Argyranthemum: Argyranthemum (marguerite, marguerite daisy, dill daisy) is a genus of flowering plants belonging to the family Asteraceae. Members of this genus are sometimes also placed in the genus "Chrysanthemum".
Document 15: Romulea bulbocodium: Romulea bulbocodium is one of the best-known species from the genus "Romulea". The plant, a member of the Iridaceae family, is native to the Mediterranean region (southern Europe, northern Africa, the Middle East) and Sudan. It has many varieties and is occasionally used as ornamental plant.
