^ This species would appear to be perennial. I scattered fresh .spores over 

 and about cultivated and unatTected plants of Ox5'ria, but without result. On 

 the other hand, an affected plant brought from Glen Tilt and grown in the 

 garden, reproduced the fungus the following year. 



- Certain species of ^uidiitiii are now con.sidered to be only forms of 

 certain polymorphic fungi, which may properly find a place in the genus 

 Uromyces. Three stages in the development of many of these fungi are either 

 known or suspected, and are thus denoted : — • 



i. The Hymenium or .luidiuni. 

 ii. The Stylospore or Uredo. 

 iii. 'J'he Teleutospore or Uroniyees. 



See ' Grevillea,' voL vii. p. 133. In the li>t I have indicated which of the 

 stages are known to me as occurring in Perthsliire.
