4 results about "Trifoliate orange" patented technology

The trifoliate orange, Poncirus trifoliata or Citrus trifoliata, is a member of the family Rutaceae. Whether the species should be considered to belong to its own genus, Poncirus or included in the genus Citrus is debated. The species is unusual among citrus for having deciduous, compound leaves and pubescent (downy) fruit. The trifolate orange was long viewed as the sole member of Poncirus, until the discovery of a second species, Poncirus polyandra, in Yunnan (China) in the 1980s.
