The pink rust is one of the old species, it having been described as long ago as 1803 by Schumacter, as Uredo Arenarise. In 1805 it was again described by De Candolle as Puccinia Dianthi, he finding it upon a species of pink, while Schumacher took it upon a sandwort. These points are brought out here to show that this is an old enemy and one that is well known to be a distinct species of rust from the one that is now causing so much anxiety among carna- tion growers. Unlike the uromyces of the carnations this puccinia has a wide range of plants upon which it may thrive. It may be found quite generally upon the members of the pink family, the genera most frequently attacked being the sand- worts, chickweeds, corncockle and occa- sionally the bouncing bet. It is thus seen that the rust of the pink is one that may be harbored by weeds, several kinds of which are common pests of the cultivated ground and spring up quickly in neglected places. The engraving shows a portion of a leaf three times magnified. There are two rust spots and these show to some extent the peculiar circular arrangement of the rust pimples. The fungus pene- trates the tissue of the leaf and after accumulating nourishment by theft forms the spots by the formation and exposure of its multitudes of spores. Plants that are badly rusted should be removed and burned. Weeds of the same lamily as the pinks which are similarly rusted should not be tolerated. While in itself it may have been worth while to call attention to this rust of the flower garden the chief point was to show in brief that this enemy is not identical with the one passing under the same gen- eral name, so ruinous to the carnations and no fears need be entertained that it will go from one ornamental plant to the other.
