Classification

Vigna mungo (L.) Hepper (1956)

synonyms:

  • Phaseolus mungo L. (1767) non Roxb. (1832) et auct.
  • P. radiatus Roxb. (1832) non L. (1753)

Linnaeus erroneously called the mung Phaseolus radiatus and the urd Phaseolus mungo. This was noticed by Roxburgh who corrected by inverting the use of such names. This arose a long period of confusion, further augmented by the shift of those species to Vigna. Unfortunately, the rules of nomenclature ICBN oblige us to follow the original choice of Linneaus for the epithet.

The wild form, var. silvestris Lukoki, Maréchal et Otoul (1980), is distributed in Maharashtra (India).

Cultivars

The most common type has black seeds graines noires ; it is called tikarī, or f. vera, and is the nomenclatural type of P. mungo L. Another type with grey seeds, f. roxburghii, is called uṛd or māsh-kulai. There are also cultivars with brownish or greenish seeds.
