ISS PUCCINIA 



The secidium of P. Conopodii- Bistort ae q.v. is sometimes to be found 

 on the same plant as the teleuto-sori of P. tumida, though it is much rarer. 



Plow-right mentions that, though the Puccini" is very common round 

 King's Lynn, he could never find the secidium which he at that time 

 wrongly supposed to be connected with it. See also Puccinia Bulbocastani. 



Distribution: France, Germany, Norway.

Spermogones. Amphigenous, mostly scattered amongst the 

 aecidia, pale-yellowish. 



^Ecidiospores. ^Ecidia hypophyllous, in smaller or larger 

 groups, often along the nerves and causing slight hypertrophy, 

 between cup-shaped and pustulate, with a whitish irregularly 

 cut margin; spores verruculose, subhyaline, 20 — 28 /z. 



Uredospores. Sori hypophyllous, scattered, minute, pul- 

 verulent, cinnamon; spores globose to 

 ellipsoid, echinulate, brown, 22 — 32 x 

 20 — 26 /i, with two (rarely three) germ- 

 pores. 



Teleidospores. Sori similar, but 

 blackish-brown; spores ellipsoid, rounded

Very similar to P. Ch.aeroph.ylli ; distinguished from it especially by 

 the uredospores, which have for the most part a thicker and darker 

 membrane with only two germ-pores. The peridium of the acidia is
