    2. That these two iEcidia are not to be distinguished from each other anatomically. 3. That Ranunculus bulbosus is the host plant upon which both Uromyces 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 telentospores 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.; 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 Jacobsea belongs to the cycle of a Carex inhabiting Puccinia—P. Schoeleriana.
