EXCLUDED SPECIES. 



I'miMViKs Pakxassi.e Cooke, Grevillea, vii. L34. 

 p. 128. 



Plowr. Ured. 



This species does not exist. The secidiutn on Parnassia, 



which was at first assigned to 

 it, is now known to belong to 

 Puccinia uliginosa (q.v.), and the 

 other stages are merely Uromyces 

 Valerianae on Valeriana dioica, 

 as has been pointed out by Sydow. 

 The leaves issued by Cooke under 

 this name (Exsicc. i. 74) are 

 obviously the radical leaves of 

 the Valerian (Fig. 290) which 

 grows in similar places to those 

 suitable for the Parnassia. In 

 Sutton Park (Warwicks.) the two plants grow side by side, and 

 when I first found the Uromyces there I put it down as U. 

 Parnassiae. Rusty marks do frequently appear on the leaves of 

 the Parnassia which are placed in herbaria as U. Parnassiae, 

 but on examination no spores will be found in them.

Uromyces Urtic^e Cooke, Grevillea, vii. 137. Plowr. Ured. p. 142. 



This also is a non-existent species. The origin of the 

 mistake can now never be unravelled. 



Uromyces scutellatus Cooke, Grevillea, vii. 137. Plowr. Ured. p. 134. 

 This is probably nothing but an error in identification. 



Puccinia asarixa Cooke, Haiidl). p. 504. Plowr. Ured. p. 202. 



This is merely Puccinia Fergussoni; the leaves on which 

 the specimens are in Cooke's Exsicc. i. 110 are obviously those 

 of Viola jxdustris. It is rather strange that the spores of 

 this species are exceedingly like the spores of the continental 

 P. asarina, and the sori are almost identical in appearance.
