producing the uredospores and teleutospores on Festuca ovina and 
duriuscula was also successfully accomplished.

Puccinia agrostidis. 
JEcidiospores— AEcidium Aquilegice. Pers. 
Uredospores. Sori bright orange, elongate or linear, seated on 
yellowish spots, amphigenous, about one mm. long, spores globose 
or oval, colourless, echinulate, contents orange, 20-25 /x. 
Teleutospores. Sori small, covered by the epidermis, sometimes 
elongate, sometimes arranged in a circular manner, dark brown, 
spores dark brown, smooth, cylindrical or subclavate, summit 
thickened, truncate or rounded, attenuated below, rather markedly 
constricted, sessile, 40-55 x 12-20 /x, average 46 x 14 /x.

The elucidation of the life history of this species was not upon 
the whole so difficult as that of the preceding. It entailed, how- 
ever, two journeys, one to the South of England, where I had the 
assistance of Mr. J. H. A. Jenner, and the other to the Lake 
district in company with Mr. H. T. Soppitt. 
In August, 1889, Mr. Jenner was kind enough to conduct me 
to the habitat of the AEcidium aquilegice in Abbot Wood, near 
Lewes. We carefully examined the grasses near the Aquilegia 
plants, and succeeded in finding on Agrostis alba some teleutospores 
of a Puccinia, the sori of which were in some cases elongated, in 
others arranged in circles or parts of circles. A supply was secured, 
and, in April, 1890, applied to a plant of Aquilegia in my garden 
at King’s Lynn. In May, 1890, Mr. H. T. Soppitt conducted me 
to a spot on the east shore of Lake Windermere, where the 
AEcidium aquilegice also occurs. We gathered not only the 
iEcidium, but also a small quantity of teleutospores on Agrostis.
