In the September number of Grevillea, Mr. Plowright adds to his articles 

 quoted above a few remarks (p. 36). 1. That the teleutospores of Uromyces 

 Pace Rabh. , previously unknown in Britain, have been found abundantly this 

 year on Poa trivialis and P. pratensis wherever these grasses grow near 

 ^/Ecidium Ficaricc. 2. That the ALcidium on Ranunculus repens is connected 

 with Urom. Poce, and not with U. Daciylidis. 3. That jEc. Rumicis is con- 

 nected with Puc. arundinacea, and that it has followed the application of 

 the spores of the Fuccinia to Rnmex obtusifolius, crispus, Hydrolapathum, and 

 conglomerates, as well as to common Rhubarb. 4. That no results have 

 followed the same application to Rumex acetosa. 5. That as there is no 

 Puccinia on Gooseberry known in Britain ALcidium Grossulariae here is not a 

 Pucciniopsis, but is"probably heteroecismal. 



As bearing on the same subject, it may be worth notice that Rostrup has 

 recently (1883) published a paper on injurious Fungi in Denmark, in P. E. 

 Mueller's " Tidskrift for Skovbrug," Vol. VI. (pp. 199 to 300), in which he 

 claims that careful observations by himself and by Nielsen have proved that 

 Jl/elampsora salicina is heteroecious, and that Ctzoma Ribesei and C. Euony?ni 

 are the ALcidia belonging to it ; and he also asserts, on the same evidence, 

 that Cceoma Mercurialis belongs to the cycle Melampsora Tremulae. 



Note. — In the Journal of Botany for September, 1883, Mr. Grove describes 

 the Puccinia (under the name P. ccgra, sp. n.) developed from the same my- 

 celium, on various species of Viola, as sEcidium depauperans of Vize, which 

 fungus would thus require to be placed in the group Auteupuccinia of Win- 

 ter's arrangement quoted above. As the ^Fxidium has been found by Dr. White 

 in Perthshire, the luccinia will probably also be found in Scotland, though 

 apparently rarely developed. The changes to which it gives rise in the host- 

 plants are so marked that its occurrence ought to be readily detected. 



ON THE SPECIES OF PHRAGMIDIUM ON BRAMBLE (RUBUS 

 FRUTICOSTJS) IN SCOTLAND. 



While preparing the paper on Scottish Uredines {vide stqira), I was led to 

 re-examine my specimens of the Phragmidium on brambles, of which I have ex- 

 amples from a good many localities in Scotland, these localities being widely 

 separated. I find that they all belong to the form known as Phr. violaceu??i 

 Sch. as stated in my paper. The other form Phr. rubi (recorded by Mr. 

 Plowright, from Yorkshire) has not fallen into my hands from any part of Scot- 

 land. Though it would be rash to assume that the latter does not occur with 

 us, the former is certainly the common species throughout Scotland. The 

 distinguishing characters will be found elsewhere in this number of the Scottish 

 .Naturalist.
