Vigna is a genus of plants in the legume family, Fabaceae, with a pantropical distribution. [2] It includes some well-known cultivated species, including many types of beans. Some are former members of the genus Phaseolus. According to Hortus Third, Vigna differs from Phaseolus in biochemistry and pollen structure, and in details of the style ...
Fabaceae are typically entomophilous plants (i.e. they are pollinated by insects), and the flowers are usually showy to attract pollinators. In the Caesalpinioideae, the flowers are often zygomorphic, as in Cercis, or nearly symmetrical with five equal petals, as in Bauhinia. The upper petal is the innermost one, unlike in the Faboideae.
The word 'bean', for the Old World vegetable, existed in Old English, [3] long before the New World genus Phaseolus was known in Europe. With the Columbian exchange of domestic plants between Europe and the Americas, use of the word was extended to pod-borne seeds of Phaseolus, such as the common bean and the runner bean, and the related genus Vigna.
A broom shrub in flower A rhododendron shrubbery in Sheringham Park. A shrub or bush is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen.
In contrast to the tiny flowers, the fruit of this species is a very large, flattened, woody pod or capsule, measuring about 1–1.2 m (3 ft 3 in – 3 ft 11 in) long and 12 cm (4.7 in) wide. They are usually slightly curved longitudinally, and have about 12 segments, each containing one seed.
Flowering usually occurs when the tree is leafless. [ 5 ] The seeds resemble beans and are orange to dark yellow in colour with a length of about 1.2 cm (0.47 in) found in pods that are 6 to 12 cm (2.4 to 4.7 in) long and 1.5 to 1.8 cm (0.59 to 0.71 in) wide.
Phaseolus (bean, wild bean) [2] is a genus of herbaceous to woody annual and perennial vines in the family Fabaceae containing about 70 plant species, all native to the Americas, primarily Mesoamerica.
