Bentham's Flora of Australia, is now the stand-dard work on Australian plants. But as in so many cases, the growth of knowledge has produced a great number of new species, not known when the earlier volumes were being prepared, and a new volume as a supplement might be issued. This, however, is a work of great magnitude, and it may be some years before it is completed. Baron Mueller, whose work did so much to make the Flora of Australia possible, may give this supplement at some time; and in the meantime he gives this list, which is an excellent substitute; for he not only gives the names of everything known to 1882, but references to the works in which they were originally described. By this those who are studying Australian plants in the vicinity of good libraries, can identify those not included in the main work.

American scientific men are accustomed to hard labor, and get through with an immense amount of solid work. But with all this familiarity with intelligent industry it is yet a marvel how Dr. Mueller accomplishes so much.
