Infection and parasitism in Uredineae, being studies of the rusts of the asparagus and carnation, and the parasitism of Darluca filum
Abstract
Of the diseases common to asparagus, the rust, on account of the rapidity with which it reduces the vitality of the plants, is more important and requires more careful consideration. It has probably always been present to a limited extent ever since there has been asparagus for it to feed upon, but not in sufficient. quantity to attract special attention until 1805 when DeCandollel described it as follows:- "It is rather common in autumn upon the stems, the branches and the leaves of the officinal asparagus; it forms oval or more often, oblong, brown, convex spots; the epidermis splits longitudinally; the teleutospores are inserted and strongly fixed on a hard and fleshy receptacle; each of the spores is composed of a white pedicel which supports an oblong, obtuse pericarp, composed of two spores.
