Initially, C. crassifolia was described as a synonym of Citrus japonica.[3] Howerver, recent phylogenetic analysis suggested that C. crassifolia is a single 'true' species.[2][1][4]

C. crassifolia was brought to Japan from China at the end of the 19th century. It is a hybrid of Nagami and Marumi. It has seedy oval fruits and thick leaves and was characterized as a different species by Swingle.[1] Its fruit is typically eaten skin and all.[5]
