rium of P. foveolaris, underwhich, however, it was never published. After the lapse of several years Mr. Carson* brought me fromMelbourne (Australia) specimens of the same Puccinia on the leavesof Jifalva rotundifolia and the common Hollyhock, with the in-formation that it is so common on Hollyhocks that the cultivationof them is hopeless. On several occasions the same complaint has been made in thiscountry, and at the same time it appeared that the parasite wasattacking different species of Mallow in several parts of the country.Mr. Broome first sent me specimens, and I have since received itfrom Mr. N. fteid, in July, 1873. M. Durieu de Maisonneuve received the same on indigenous speciesof Malva in April, 1873, and has given an account of its suddenappearance and prevalence in France, in the department of LaOironde.f * See Gardeners Chronicle, Sep. 2, 1865. f Actes de la Societe Linneenne de Bordeaux, t. xxiv., 1873.

I have, indeed, another species onMalvaceae—viz., Puccinia Abutilt, B. & Br. Fungi of Ceylon, No.816, on Abutilon graveolens, which also has been gathered by Mr.Ayres, on a species of Sida, in Mauritius. This has much shorter,obtuse, and very different pseudospores. I have also a closely-allied species, Puccinia sepulta, B. &. Curt., Proc. Am. Ac. iv.,p. 126, on some uncertain plant. P. malvacearum is figured by Corda from specimens com-municated by Dr. Montagne, Ic. Fasc, vi., p. 4, t. I, f. 12, andmy own analysis exactly accords with his figure. Mr. Carsons specimens were received in this country in 1865but we have no information as to the time of the first appearanceo
