PUCCINIA. 351 



p. sylvatica Schroet. (Britain). Uredo- and teleutospores on 

 Carex; aecidia on some Compositae. Schroeter^ regards an 

 Aecidium on Taraxacum officinale and Senecio nemorensis as 

 related to the teleutospores on Carex hrizoides and C. praecox. 

 Klebahn^ reared aecidia on Taraxacum after infection with 

 teleutospores from Carex arenaria ; E. Fischer obtained aecidia 

 only on Taraxacum qfflcinale. Dietel ^ regards Aecidium 

 Bardanae on Arctium Lappa as related to this species. 



Attacked leaves of Taraxacum are frequently much deformed, 

 stunted, and twisted. Those of T. officinale have orange-red 

 warts on the lower surface, and there Fentzling {loc. cit.) found 

 both spongy and palisade parenchyma increased and more or 

 less deformed, the cells being elongated and enclosed in 

 hyphae. 



P. leucanthemi Pass. According to E. Fischer, the uredo- and teleuto- 

 spores are found on Carex montana; the aecidia {Aec. leucanthemi) on 

 Chrysanihemwrn Lexicanthemum. 



P. tenuistipes Eostr. Uredo- and teleutospores on Carex murica.la ; 

 aecidia on Centaiirea. 



P. arenariicola Plowr. et Magn. On Carex arenaria ; aecidia = .4 ee. cent- 

 aureae on C. nigra. (Britain.)
