The genus Vigna is in the plant family Fabaceae. The genus is named after Dominico Vigna an Italian botanist of the 17th century. Many Vigna species are cultivated for food. They include some well-known and not so well known bean species formerly included in the genus Phaseolus. Common names in this genus reflect its mixed taxonomic history as some are referred to as peas and others as beans. See genus (mathematics) for the use of the term in mathematics. ...

Many references even in current literature will place some of these species in genus Phaseolus. According to Hortus Third, however, Vigna differs from Phaseolus in that

• plants in Vigna often have stipules that are appendaged
• the thickened part of the style is less strongly twisted
• details of the pollen
• details of the biochemistry

Examples of Vigna species cultivated for food include: SEM image of pollen grains from a variety of common plants: sunflower (Helianthus annuus), morning glory (Ipomea purpurea),hollyhock (Sildalcea malviflora), lily (Lilium auratum), primrose(Oenothera fruticosa), and castor bean (Ricinus communis). ...

• V. caracalla

Note: Based on the taxonomy in the 2 references below (supported by hundreds of taxonomists)the black-eyed pea is not ssp. dekindtiana but v. unguiculata ssp. unguiculata. "dekindtiana" refers to a wild subspecies. If the editors disagree with this view they should remove the references / links below. I am not completely familiar with the American vernacular but I wonder if "Cowpea", "Black-eyed pea", and "Southern pea" should not be under the same botanical name. Given that they are neither the catjang type nor the yardlong type, nor presumably the wild type, they can only be ssp. unguiculata. Binomial name Vigna caracalla (L.) Verdc. ...
