Cabbagerot, bulb-rot of hyacinths, &c., carnation disease-there is evidence that bacteria are causally connected with the disease.
Smith, Book of the Carnation; J.
GILLYFLOWER, a popular name applied to various flowers, but principally to the clove, Dianthus Caryophyllus, of which the carnation is a cultivated variety, and to the stock, Matthiola incana, a well-known garden favourite.
The name was originally given in Italy to plants of the pink tribe, especially the carnation, but has in England been transferred of late years to several cruciferous plants."
Saprophytic bacteria can readily make their way down the dead hypha of an invading fungus, or into the punctures made by insects, and Aphides have been credited with the bacterial infection of carnations, though more recent researches by Woods go to show the correctness of his conclusion that Aphides alone are responsible for the carnation disease.
Cabbages, cucumbers, potatoes, &c. In the carnation disease and in certain diseases of tobacco and other plants the seat of bacterial action appears to be the parenchyma, and it may be that Aphides or other piercing insects infect the plants, much as insects convey pollen from plant to plant, or (though in a different way) as mosquitoes infect man with malaria.
A little while after I had told her that a carnation that had been given her was red, she puckered up her mouth and said, "Lips are like one pink."
