that the teleutospores vary rather much in size according to the host- 

 plants. In our specimens the teleutospores are very small, as the length 

 of the spores is 37 // max., while the breadth (which of the Tecoma 

 stans-iovxns is said to be 26 — 32 fx) is hardly more than 25 fx. 



After the description (H. et P. Sydow 1. c.) the uredo appears as 

 small point-shaped heaps sitting on yellowish spots that do not come out 

 strongly. Our specimens do not quite answer to this, as the uredo-sori, 

 though (as it seems in an early stage of development) partly being of 

 the above described appearance, will often show quite another and 

 a very characteristic aspect. Partly they appear in big heaps on sharply 

 marked yellow spots, and partly they are found on the mainridge and the 

 side-ridges of the leaf which on centimeter-long stretches are deformed 

 into (in dry stale) wood-hard swellings that are often irregularly crooked 

 and outwardly covered with a thin layer of cinnamon-coloured spores. 



This pathological appearance puts in mind Spegazzinis description 

 of the Tecoma s^aws-leaves affected by Uredo Lilloi Speg. Fung. Arg. nov. 

 V. crit. p. 234 ("Tumoribus majusculis ... in sicco sublignosis . . . extus 

 cortice prohgero tenui ferrugineo veslitis"). 



Also microscopically our uredo and Uredo Lilloi Speg. agree exactly, 

 on account of which we are allowed to presume that this one represents 

 a special rich development of the uredo-stage belonging to Puccinia ap- 

 pendiculata Wint. Hence the supposition that Uredo Lilloi Speg. represents 

 the unknown uredo-stage of PuccAnia elegans Schroet. (H. et P. Sydow 

 1. c. p. 245) surely will turn out not to be right.
