1882, Disease of Irises 2

Gardeners' Chronicle p49, July 8, 1882

Disease of Iris.— Mr. W. G. Smith writes to inform us that, since the last meeting of the Scientific Committee of the Royal Horticultural Society, he has received from Mr. R. I. Lynch, of Cambridge, leaves of Iris Pseud-acorus badly infected with the fungus (Puccinia truncata) in its perfect condition. This is, we believe, the first record of this Iris being affected, and the first observation of Puccinia on Iris this year. We shall shortly illustrate the subject, and in the meantime we advise growers of choice Irises to look to their plants. An early symptom is the presence of yellowish-brown stains on the leaves, then little brown scattered pustules the size of a large pin's head, followed by black pustules of a larger size.
