It has been proved that Aecidium asperifolii Pers. which was for- 

 merly considered st. I of all the species united under Puce, rubigo is 

 only corresponding to Puccinia dispersa. Fr. Miiller has proved that an 

 aecidium on Symphytum corresponds to Puce, bromina, but both the 

 said aecidial-forms have not by far as great a distribution as the corre- 

 sponding uredo-forms, so it seems as if they are able to propagate 

 independent of their aecidial stage, and vice versa. It may be conclu- 

 ded from this that all the species of Puccinia living on Gramineae 

 will occasionally produce st. I, as is also known from Puce, obscura, 

 many species of Melampsora etc.

 perifolii Pers. Syn. =°^ Schum. no 1509, Fl. D. tab. 2219 fig. 1, Aec.

St. I occurs in August— October on Anchusa arvensis and officina- 

 lis, common; Schumacher states that he has found it on Echium vul- 

 gare and the same information is often repeated later on (for instance 

 Lange 79), but nobody has found cluster-cups again on this host-plant 

 so I suppose it to be a mistake. P. Nielsen has infected Secale cereale 

 with Aecidium asperifolii (P. N. 77 a) as also Tritieum but with grea- 

 ter difficulty. Rostrup has published st. I on Anchusa officinalis in 

 Thum. herb, mycol. oeconomic. no. 267. St. II— III occur on Secale 

 (Er. 00) and are very common on this host-plant all the year round. 



St. I. Anchusa arvensis &. officinalis. St. II— III. Secale anatolium, cereale, 

 fragile.

St. I on Symphytum hitherto not found in Denmark; st. II &. Ill 

 common on all species of Bromus (inel. Schedonorus) during the gro- 

 wing season. P. Nielsen has noticed hibernating uredo on Bromus 

 commutatus Vs 1874. 



St. II 6^ III are noticed in Denmark on Bromus arduennensis, arvensis, bri- 

 zaeformis, commutatus, hordaceus, Hughii, mollis, purpureas, racemosus, secali- 

 nus, sterilis, tectorum.
