FAR RIGHT    This drawing is taken from the 1909 second edition of the book by F.M. Bailey entitled 'Comprehensive Catalogue of Queensland Plants Both Indigenous and Naturalised'. It shows Citrus inodora, Citrus australasica, Citrus australis and Citrus garrawayi. Over the years these have been re-classified first as Microcitrus, and then recently put back into the citrus family. This is one of the very few pictures I have seen that include fruit of  Citrus inodora and Citrus garrawayi. For size comparison I would guess that the Fingerlime (C. australasica) is about 6cms long.

RIGHT   This picture is from 'The Citrus Industry, Volume 1' It shows A, branch of Round lime; B, fruits of Round lime; C, branch of Sydney Hybrid; D, fruits of Sydney Hybrid;  E, branch of Finger lime with fruit.
