I^HE occurrence of a plant when for many years one has been 

 searching for it gives joy to the discoverer. In the month 

 of July in this year I was fortunate enough to find an 

 (Ecidium growing on Galium aparine, and before putting it under 

 the press for the purpose of drying, I noticed on the lower part of 

 the stems of the Galiimi, some intensely black bullate swollen 

 patches, which were unhesitatingly Fucci?ii(i. They might fairly 

 be taken to be the teleutospore of the (Ecidium. At once 1 took 

 it to be Puccinia difformis, a fungus w^hich is very unusual in 

 England — at least, so far as my searchings have gone ; so also 

 those of Dr. Cooke, because I well remember at the Woolhope 

 Foray last year, at the Forest of Dean, when Fucci?iia acumifiata 

 was found on Galium saxaiile^ he asked if I had ever met with 

 F. difformis. My answer was No. He had only found it once, I 

 believe, the locality being Shere, in ^Surrey. 



Thus far we have noticed two Puccinias growing on Galium.^ 

 Fuc. difformis on Galium aparine, and Fuc. acuminata on Galium 

 saxatile. But there are two other Fuccinias also growing on 

 Galium according to the Handbook, namely, Fuc. Vala?ifice 

 (Pers.) on Galium cruciatuvi and Fuccinia Galiorum (Lk.) on 

 various species of Galium. 



On referring to Prof. Saccardo's Sylloge, Vol. vii., p. 600, he 

 gives no less than thirteen species of Galium., two of Asperula, 

 and one of Rubia as the host plants of Fuc. Galii (Pers.). As 

 a synonym he gives Fuccinia difformis (Kunze), about which we 

 shall say a little presently. Let me merely say with regard to Fuc. 

 Galiorum that this plant has its four forms of spores on the same 

 plant in orthodox succession, and they are easily traced from the 

 oecidial stage to the teleutospore. 



At page 685, Prof. Saccardo gives Fuccinia Valantice (Pers.) as 

 growing on five species of Galium and tw^o of Afollugo, four of 

 the Galium having been the habitats of the previously recorded
