    JIab. On the lower surface of the leaves of Tussilugo Petasiles, in autumn, common. This plant bears considerable resemblance to the last. It never grows in a circular manner, but frequently spreads irregularly over a whole leaf; and ought not to have been included by Strauss under his U. circiualis. In the Flora Scolica, II. TussUaginis is stated to grow on Tussilago Petasites, which mistake probably originated in myself, as I sent the species to Dr Hooker. 38. U. Populinn, hvpophyllous, scattered or crowded, dis- tinct, convex, roundish, large compared with the following, mostly closed, pale, becoming golden-yellow ; sporidia very long, obtuse at each extremity.

On the lower surface of the leaves of Populus nigra and balsamifera, in autumn, rather rare. Carlowrie, and near Newhaven. A very distinct and beautiful species, with remarkably long sporidia. In Hooker’s Flora Scolica, it is said, on my authority, to grow on Populus trcmula also, which is erroneous. 39. U. ovata, hypophyllous, punctiform, prominent, or pa- pilliform, numerous, tawny yellow, mostly closed ; sporidia ovate. Strauss in Annal. Soc. Wetterav. v. 2. p. 92. t. 11. f. 6. /3.

De Candolle unites var. p>. and Persoon's U. jxtpulina with his U. longicap- sula; hut INI. Strauss has, with great propriety, separated them. *** Dust white. (Albugo.) 40. U. Candida, polymorphous, of various forms, sometimes disposed in a circular manner, quite white, frequently never bursting; sporidia in great profusion, globular, transparent un- der the microscope. Pers. Syn. Fung. p. 223. Uredo TIdas pi, Sow. Fung. t. 340. U. crucifer arum, De Cand. Syn. p. 49. Hab. On plants belonging to the Natural Order Cruciferce, (Class Tclra- dynamia, Linn.), attacking the leaves, stems, calyx, and even the seed- vessel; from the commencement of spring to the end of autumn. Kx- tremely common on Thlaspi Bursa-Pa#toris, and Erysimum officinale, Coch- learia armoriaca, and different species and varieties of Brassica, in gar- dens. 1 believe it to be very doubtful whether there is more than one white Uredo known. **** Dust black-brown, or violet, attacking the fructification ofplants.
