Question: Between the Lime and the Exochorda, which can be expected to have more variety between individual plants?

full_context: Document 1: Tamarindo (drink): Agua de tamarindo is an agua fresca drink typically served throughout Latin America. It is made from tamarind (a legume: tamarindus indica) after it has been boiled in water, has had its seeds removed, and has been liquefied and combined with sugar. It is typically sold at taquerías in Mexico, and central and south American restaurants. It has gained popularity also in the United States and elsewhere. Tamarindo is also sold as a flavor of soda, the first of which was produced by the company Jarritos.
Document 2: Limca: Limca is a lemon and lime flavoured carbonated soft drink made primarily in India and certain parts of the U.S. It contains 60 calories per 150ml can. The formula does not include fruit, relying instead on artificial flavors.
Document 3: Corylopsis: Corylopsis is a genus of nearly 30 species of shrubs in the witch hazel family, Hamamelidaceae, native to eastern Asia with the majority of species endemic in China but with some also in Japan, Korea, and the Himalayas. This genus is also known from the extinct species "Corylopsis reedae" described from Eocene leaf fossils found in Washington State, USA.
Document 4: Pseudocydonia: Pseudocydonia sinensis, the Chinese quince, is a deciduous or semi-evergreen tree in the family Rosaceae, native to eastern Asia in China, and the sole species in the genus Pseudocydonia. It is closely related to the east Asian genus "Chaenomeles", and is sometimes placed in "Chaenomeles" as "C. sinensis", but notable differences are the lack of thorns, and that the flowers are produced singly, not in clusters. The Chinese quince is also closely related to the European Quince genus "Cydonia"; notable differences include the serrated leaves, and lack of fuzz.
Document 5: Gimlet (cocktail): The gimlet (pronounced with a hard 'g') is a cocktail made of gin and lime juice. A 1928 description of the drink was: "gin, a spot of lime, and soda". The description in the 1953 Raymond Chandler novel "The Long Goodbye" stated that "a real gimlet is half gin and half Rose's lime juice and nothing else". This is in line with the proportions suggested by "The Savoy Cocktail Book" (1930) which specifies one half Plymouth Gin and one half Rose's Lime Juice Cordial. However, modern tastes are less sweet, and generally provide for at least two parts gin to one part of the lime and other non alcoholic elements (see recipes below).
Document 6: Paulownia: Paulownia is a genus of six to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, related to and sometimes included in the Scrophulariaceae. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. They are deciduous trees 12 – tall, with large, heart-shaped leaves 15–40 cm across, arranged in opposite pairs on the stem. The flowers are produced in early spring on panicles 10–30 cm long, with a tubular purple corolla resembling a foxglove flower. The fruit is a dry capsule, containing thousands of minute seeds.
Document 7: Exochorda: Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan). They are used as ornamental plants with the common name pearl bush, or pearlbush. Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss. As a single species the correct name is "E. racemosa".
Document 8: Chaenomeles: Chaenomeles is a genus of three species of deciduous spiny shrubs, usually 1–3 m tall, in the family Rosaceae. They are native to Japan, Korea, China, Bhutan, and Burma. (Burmese: ချဉ်စော်ကား ) These plants are related to the quince ("Cydonia oblonga") and the Chinese quince ("Pseudocydonia sinensis"), differing in the serrated leaves that lack fuzz, and in the flowers, borne in clusters, having deciduous sepals and styles that are connate at the base.
Document 9: Lemon liqueur: Lemon liqueur is a liqueur made from lemons, liquor, and sugar. It is light to bright lemon yellow in color; intensely lemony in flavor; clear, cloudy, or opaque; and sweet or sweet and sour. Lemon zest is used, water may be added, and the liqueur is not sour. Milk or cream may be added to make a lemon cream liqueur. Lemon juice is not used to alter the taste and affect the stability of the lemon liqueur.
Document 10: Chaenomeles: Chaenomeles is a genus of three species of deciduous spiny shrubs, usually 1–3 m tall, in the family Rosaceae. They are native to Japan, Korea, China, Bhutan, and Burma. (Burmese: ချဉ်စော်ကား ) These plants are related to the quince ("Cydonia oblonga") and the Chinese quince ("Pseudocydonia sinensis"), differing in the serrated leaves that lack fuzz, and in the flowers, borne in clusters, having deciduous sepals and styles that are connate at the base.
Document 11: Rosa × odorata: Rosa" × "odorata or Rosa odorata is a member of the genus "Rosa" native to Yunnan in Southwest China, whose taxonomy has been confused. It has been considered to be hybrid between "Rosa gigantea" and "Rosa chinensis", or as a quite rare wild species that includes "R. gigantea". The wild forms are cultivated to some extent. Cultivars were developed in China in ancient times from "R. chinensis" crosses, and these have been important in the ancestry of the tea-scented China roses, also called tea roses, and their descendants the hybrid tea roses.
Document 12: Passiflora laurifolia: Passiflora laurifolia, commonly known as the water lemon, Jamaican honeysuckle, golden bellapple, pomme liane on Martinique & Guadeloupe and orange lilikoi (yellow lilikoi, or simply lilikoi, is the name given to passiflora edulis v. flavicarpa for the valley where it first grew in Hawai'i), is a species in the family Passifloraceae. It is native to tropical Americas. The water lemon is an invasive plant in its home region, and has spread to other parts of the world. As a tropical species, water lemon will not tolerate any frost. Water lemon is only occasionally cultivated, but the fruits are usually available in markets wherever the vine grows in wild. It is not yet widely known outside those regions.
Document 13: Lime (fruit): A lime (from French "lime", from Arabic "līma", from Persian "līmū", "lemon") is a hybrid citrus fruit, which is typically round, lime green, 3 – in diameter, and contains acidic juice vesicles.
Document 14: Variegated pink lemon: The variegated pink lemon, also called the variegated Eureka lemon, or pink-fleshed Eureka lemon is a cultivar of lemon ("Citrus" × "limon") with unique pink flesh, a green-striped rind when ripening, and variegated foliage. It was discovered as a sport on an ordinary Eureka lemon tree in Burbank, California in 1931.
Document 15: Lemon drop (candy): A lemon drop is a sugar coated, lemon-flavored candy that is typically colored yellow and often shaped like a miniature lemon. They can be sweet or have a more sour flavor. Lemon drops are made by boiling sugar, water and cream of tartar until it reaches the hard crack stage. As the mixture cools, lemon flavor is added. The candy is then rolled into long ropes, cut into small pieces and rolled in sugar. Lemon drops originated in England, where confectioners learned that adding acid such as lemon juice to the boiled sugar mixture prevented sugar from crystallizing.
