DeBary (Monatsber. K. Akad. d. Wiss. Berlin 25. 1865) was the 

 first to show that the well known Piiccinia graininiii developed its aecial 

 form on Berberis. In 1864 he first sowed telia from Agropyron repens 

 and Poa pratensis on leaves of Berberis resulting in the development of 

 pycnia and aecia. He later (1865) infected Secale ccreale by sowing 

 aeciospores from Berberis. This is the first record of the connection 

 of two stages of an heteroecious rust by inoculation. Since DeBary's 

 first publication of the life history of this species a large number of 

 mycologists in all parts of the world have conducted culture work con- 

 firming DeBary's results and adding to our knowledge of the species. 

 For a review of this work see Klebahn (Die Wirtswechs Rostpilze Berlin 

 205-235. 1904).
