A SURVKY OF THE LOWER TEKS MARSHES 139 



flowering. Pycnidia and aecidia on Pulicaria dysenterica ; 

 uredospores and teleutospores on y^uiicus glancus, and 'y. 

 effusus. I have never seen the latter on yunci named by 

 Massee. 



6. Uromyces scirpi, Burr. Somewhat sparingly in the 

 various Saltholme Scirpits maritimns beds furthest away from 

 Greatham Fleet, but commoner on Mucky and Swallow Fleet ; 

 this perhaps explains the weakened condition of the plant there. 

 Pycnidia and aecidia on Glaux maritima ; uredospores and 

 teleutospores on various forms of Scirpns inaritiinus. 



7. Uromyces poae, Rabenhorst. Rather common near 

 Norton Mill. Pycnidia and aecidia on Ramiiiculus repens ; 

 uredospores and teleutospores on Poa trivialis. 



8. Uromyces chenopodii, Schroet. ,Rare on Snaeda maritima 

 in Greatham Marsh. When I recorded this in the Vasculum, 

 Dec, 1917, page 128, I did not know that this was a new 

 British record ; such is, however, the case. 



Puccinia, Persoon. 



1. Puccinia absinthii, D. C. Common enough on the 

 Artemisia maritima on the north side of Greatham Fleet ; not 

 seen on the southern half. 



2. Puccinia centau?-eae, Mart. Rather unusual on Centaurea 

 nigra in Billingham Bottoms. 



3. Puccinia obtegens, Tul. Very common throughout the 

 area on Cirsium arvense: easily recognisable by its fragrant 

 smell. 



4. Puccinia menthae, Pers. Not common on Mentha spp., 

 but generally distributed in the vicinity of Billingham. 



5. Puccitiia epilobii-tetragoni, Winter. Surprisingly scarce 

 on Epilobium hirsutum in the osier bed at Billingham. 



6. Puccinia caricis, Rebent. Once only, teleutospores on 

 Carex paludosa in the Caricetum paludosae at Billingham ; 

 aecidia on Urtica dioica.
