Question: Morning glory and Sorbus are both a genus of plants? 

full_context: Document 1: Ipomoea nil: Ipomoea nil is a species of "Ipomoea" morning glory known by several common names, including picotee morning glory, ivy morning glory, and Japanese morning glory. It is native to most of the tropical world, and has been introduced widely.
Document 2: Ipomoea cairica: Ipomoea cairica is a species of morning glory which has many common names, including mile-a-minute vine, Messina creeper, Cairo morning glory, coast morning glory and railroad creeper. This vining perennial has palmate leaves and large, showy white to lavender flowers. Each fruit matures at about 1 cm across and contains hairy seeds.
Document 3: Commelinaceae: Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include "Commelina" (dayflowers) and "Tradescantia" (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms.
Document 4: Ipomoea wrightii: Ipomea wrightii, or Wright's morning glory, is a species of morning glory.It is generally described as an annual, perennial vine or forb or herb. Wright's morning glory is not native to the United States and is considered as an invasive species. It is found growing in the Southeastern part of the United States.
Document 5: Photinia: Photinia ( ) is a genus of about 40–60 species of small trees and large shrubs, but the taxonomy has recently varied greatly, with the genera "Heteromeles", "Stranvaesia" and "Aronia" sometimes included in "Photinia".
Document 6: Corymbia: Corymbia is a genus of about 113 species of tree that were classified as "Eucalyptus" species until the mid-1990s. It includes the bloodwoods, ghost gums and spotted gums. The bloodwoods had been recognised as a distinct group within the large and diverse "Eucalyptus" genus since 1867. Molecular research in the 1990s, however, showed that they, along with the rest of the Corymbia section, are more closely related to "Angophora" than to "Eucalyptus", and are probably best regarded as a separate genus. All three genera—"Angophora", "Corymbia" and "Eucalyptus"—are closely related, often difficult to tell apart, and are still commonly and correctly referred to as "eucalypts". Groups of naturalists and conservationists do not recognise the "Corymbia" genus and still categorise its species within "Eucalyptus".
Document 7: Maple: Acer is a genus of trees or shrubs commonly known as maple. The genus is placed in the Sapindaceae family. There are approximately 128 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, "Acer laurinum", extends to the Southern Hemisphere. The type species of the genus is the sycamore maple, "Acer pseudoplatanus", the most common maple species in Europe.
Document 8: Sorbus × pinnatifida: Sorbus" × "pinnatifida is a widely cultivated ornamental shrub that is thought to be a form of "Sorbus" × "thuringiaca" (Nyman) Schonach. It is cultivated by grafting.
Document 9: Sambucus: Sambucus is a genus of flowering plants in the family Adoxaceae. The various species are commonly called elder or elderberry. The genus was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in the genus "Adoxa". In "Sambucus", there are between 5 and 30 species of deciduous shrubs, small trees and herbaceous perennial plants.
Document 10: Rubus: Rubus is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with 250–700 species.
Document 11: Sorbus: Sorbus is a genus of about 100–200 species of trees and shrubs in the rose family Rosaceae. Species of "Sorbus" ("s.l.") are commonly known as whitebeam, rowan, service tree, and mountain-ash. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species. Recent treatments treat "Sorbus" in a narrower sense to include only the pinnate leaved species of subgenus "Sorbus", raising several of the other subgenera to generic rank.
Document 12: Evolvulus: Evolvulus is a genus of flowering plants in the Convolvulaceae, the morning glory family. They are known generally as dwarf morning glories. Most all are native to the Americas. There are about 100 species.
Document 13: 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 14: Sorbus alnifolia: Sorbus alnifolia (syn. "Aria alnifolia"), also called alder-leafed whitebeam, Korean whitebeam, or Korean mountain ash, , is a species of whitebeam native to eastern Asia in eastern and northern China, Taiwan, Korea and Japan.
Document 15: Morning glory: Morning glory (also written as morning-glory) is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux. Morning glory species belong to many genera, some of which are:
