2. That these two iEcidia are not to be distinguished from 
each other anatomically. 
3. That Ranunculus bulbosus is the host plant upon 
which bothUromyces dactylidis and Puccinia Magnu- 
siana have their secidiospores, which in like manner are 
anatomically indistinguishable. 
4. That Uromyces pose has its secidiospores upon Ranun- 
culus ficaria and R. repens. 
5. That Uromyces dactylidis in this district has its Uredo 
without capitate paraphyses. 
6. That the iEcidium upon Ranunculus acris belongs to 
the life cycle of Puccinia perplexans, a Puccinia the 
teleutospores of which occur upon Alopecurus pratensis, 
Avena elatior, and Poa sp. (?), bearing a close resemblance 
to those of P. rubigo-vera, but wanting the dark paraphyses 
of the latter species. 
7. That the uredospores of P. perplexans are sometimes 
mixed with capitate paraphyses and sometimes without 
them. 
8. That Puccinia phragmitis has its secidiospores upon 
Rumex hydrolapathum, R. obtusifolius, L. ; R. cris- 
pus, L.j R. conglomeratus, Mur., and Rheum officinale. 
9. That P. Magnusiana has its secidiospores upon Ranun- 
culus repens and R. bulbosus. 
10. That the iEcidium upon Rumex acetosa is neither 
connected with P. Magnusiana nor with P. phragmitis. 
11. That the iEcidium on Senecio J acobsea belongs to the 
cycle of a Carex inhabiting Puccinia — P. Schoeleriana.
