host in Scotland, but differs in the absence of uredospores, the 

 hypophyllous sori and the distinctly thickened apex of the 

 teleutospore. 



P. Tripoli: Wallr. 



On Aster Tripolium L., Aberlady, Haddington, Sept. 1921. 



Only previously recorded in Scotland from the Tay and Dee 

 areas. 



P. SoNCHi Rob. 



This rust appears to be widespread in Scotland. It has already 

 been recorded by Trail from Aberdeen, by Johnson from Berwick 

 and by Boyd in Ayrshire. It was not uncommon near Berwick 

 and in the neighbourhood of Edinburgh in 1922 and was also 

 found by Professor Scott Elhott in Kirkcudbrightshire. In these 

 cases only uredospores were present. Teleutospores were how- 

 ever found on specimens collected at Brantingham near Hull 

 in September 1922, and this appears to be the first occasion on 

 which this spore-form has been found in Britain. 



P. PALUDOSA Plowr. 



Aecidia on Pedicularis palustris L. and uredospores and 

 teleutospores on Carex Goodenovii Gay, Taynuilt, Argyll, August 

 1921, and Lumphanan, Aberdeen, July 1922. 



Previously recorded from Norfolk and by Trail from Orkney. 

 Aecidiospores placed on Carex Goodenovii on July 24th produced 

 uredo-, and teleuto- and mixed sori on the upper surface of the 

 leaf on August 21st, 1922. 



P. MiRABiLissiMA Peek. 



Uredospores and teleutospores on Berberis Aquifolium Pursh., 

 Colinton, near Edinburgh, January 1923, and Newlands, Peebles- 

 shire, July 1923. 



This appears to be the first European record of this species 

 which has hitherto only been found in some of the western 

 United States and in Washington (see Trans. Bot. Soc. Edin. 

 xxviii, 1923, p. 164). 



P. ZoPFii Wint. 



Uredospores and teleutospores on Caltha palustris L., Tajmuilt, 

 Argyllshire, July 192 1, and Lumphanan, Aberdeen, July 1922. 



A Scottish specimen of this rust is preserved in the herbarium 

 of the British Museum (see Trans. Brit. Myc. Soc. iv, 1913, p. 185) 

 and its discovery in the localities mentioned above appears to 

 indicate that it is widespread in Scotland. It is also recorded 

 from England and Ireland. It has probably been confused with 

 P. Calthae Link but differs from this species in its broader 

 teleutospores.
