Abstract:An intergeneric graft chimera between Citrus reticulata 'Ponkan' and Poncirus trifoliata (L.) Raf. was found in a farmholding orchard in Juxi Town, Liancheng County, Fujian Province, in 1986, which was obtained from the buds appeared after freezing damage in graft union of 2-year-old seedling of cultivar 'Ponkan' grafted on the stock of Poncirus. The graft chimera is named as + Citroponcirus 'Hormish'which has unifoliate, bifoliolate and trifoliolate leaves in some branches, and trifoliolate in other branches, showing a chimera of the two species. Young fruits are pubescent as those in Poncirus. Mature fruits are similar to 'Ponkan' in shape and in flavour, but some have the appearance of chimera character of both Poncirus and 'Ponkan'. Juicy pulp is mostly orange-red in colour with a few yellowish pulp. This report aims to give and disscuss the name of this chimera which is unique in Rutaceae.
