A LIST OF THE INDIGENOUS PLANTS OF THE MUDGEE DISTKICT. By Alexander G. Hamilton. In my list of tlie Orchidese of this district (Proc. Linn. Soc. of N.S.W., Vol. I., 2nd Ser. 1886, p. 865), I promised at some future time to furnish a list of the phsenogamous plants and the ferns. That promise I now fulfil in the hope that it may be of some use in the elucidation of the question of the geographical distribution of species. The remarks that applied to the distribution of orchids in this ■district, apply equally to the other families The sandstone found on the Dividing Range supports the plants that are typical of the sandstone elsewhere. But there is, among the remaining families a greater proportion of species differing from the coast forms than is found among the orchids. These differing forms however, appear to be representatives of the coast plants. In one or two sheltered spots there are many species not occurring elsewhere about Mudgee. For example, in a deep gully at Mullamuddy are found Fittosjjorurn undulatum, Eucalyj)-tus globulus, Nicotiana sioaveolens, Sambucus xanthocarjm, Sturmia re/lexa, Dendrobium sjieciosicm, and Pteris aquilma, none of which occur generally over the district, although the last three grow at Cooyal, on the Dividing Range. Some other plants, rare else-where, are common in this ravine.
