twisted and swollen and densely set with cluster-cups. As all fallen 

 leaves are removed every year I suppose that the fungus has a peren- 

 nial, aecidial mycelium; Klebahn has made the same observation (98 ^°), 

 and Plowright writes (89 ^°°) : "The aecidiospore mycelium is probably 

 perennial, at least this appears to be the case with Mentha viridis, 

 which I have cultivated for a period of three years". (See also Hariot 

 08"). St. I often occurs on Clinopodium, Rostrup has also found it a 

 few times (92 g '''') on Mentha aquatica and Origanum vulgare, but 

 on the rest of the host-plants stated below only st. II &. Ill are found; 

 St. I April— June, st. II June— Septbr. ; st. Ill October.

Aut-eu-puccinia, the mycelium of the aecidiospores is perennial, 

 and causes the affected plants to produce shorter and thicker leaves 

 (see Plowright 85 "'). 



Vinca major. S. Kabenhavn '•^/n 1888. 



Puccinia compositarum Schlecht., Puce, synanthearum and Puce, 

 inquinans Wallr. 



They are common names used at differents periods by different 

 authors for indicating more or less of the species of Puccinia occurring 

 on Compositae; Rostrup often used these common names in his 

 papers; recent mycologists (P. Magnus, Jacky, Bubak, Fischer etc.) 

 have tried to separate the single species and to determine their proper 

 limitation.
