Notes and observations

EMN, 12/22/1987: Ratty tree- much dieback. Fruit all on ground; about the size and shape of a fat, stubby finger lime. Rind medium orange, about as smooth as a navel orange. Rind very thin, few seeds, green flesh, juicy, very sour.

Description from The Citrus Industry Vol. 1 (1967)

"The faustrimedin is a hybrid of the Australian finger-lime with the Calamondin, itself a hybrid between the kumquat and some variety of orange of the mandarin group (Citrus reticulata). It is thus a trigeneric hybrid of Citrus, Fortunella and Microcitrus. The faustrimedin has small leaves much like those of the Australian finger-lime and is hardy like the Calamondin.

This hybrid, first made by Oliver (1911, p. 40, pl. 1, fig. 2), may be of use in obtaining still more complex hybrids containing the blood of Eremocitrus or Poncirus. It is a vigorous grower and shows some promise as a rootstock. It is easily propagated from cuttings. The fruits are like finger-limes but are shorter, nearly seedless, and pleasantly acid."
