Citrus margarita
Species of kumquat
Citrus margarita, the oval kumquat[4] or Nagami kumquat,[5][6] is a species of kumquat;[1] a type of citrus fruit in the genus Citrus, family Rutaceae.[7] Its epithet, margarita, is Latin for pearly.[8]
It is first described by the Portuguese botanist João de Loureiro in 1790, in his Flora cochinchinensis under the name Citrus margarita.[7][9] It is described again by the American botanist Walter Tennyson Swingle in 1915, as varieties of Citrus japonica.[10] However, recent phylogenetic analysis suggested that C. margarita is a single 'true' species.[1][2][7][11]
