will unite this species with all the other species of Uromyces which 

 have their st. Ill on Scirpus maritimus. However, as long as the oppo- 

 site is not proved, I should consider it right only to unite the species 

 of Uromyces, having their st. I on Umbelliferae and their st. II &. 

 Ill on Scirpus maritimus, under the name of Uromyces scirpi, and 

 for the present to consider the forms not having their st. I on Um- 

 belliferae as independent species. 



It is very common, and is seldom sought in vain in places where 

 both host-plants are found on beaches. Found for the first time in 

 this country at Magaard near Skaarup June 17. 1875. Specimens from 

 Denmark (Christiansminde near Svenborg June 15. 1877) are distri- 

 buted in Thiimen's Mycotheca no 1021.
