Mr. R. Fitzgerald, the Deputy Surveyor-General of New South Wales, has issued another part of his admirable work on Australian Orchids. " This " says a correspondent " is the fifth decade of an opus in large folio size with colored plates drawn from living specimens, and illustrative of a charming tribe of our vegetation. The work is evidently intended to embrace in course of time all the or-chideous plants of Australia, and will greatly facilitate the recognition of many of these lovely species".
