Arthur: Cultures of Uredineae

May 9 on Lycopus americanns, giving rise to pycnia May i6, and 
aecia May 24. Another collection believed to be the same rust 
and on the same host, collected at London, Ontario, by J. Dear- 
ness, was sown May 13 on L. Americanus, giving rise to pycnia 
May 20, and aecia May 27. Corresponding cultures have been 
made many times before.^® The rust is very common throughout 
the eastern United States, especially northward, but has not been 
seen in the Rocky mountain region or on the Pacific coast. Pro- 
fessor Peck based the name, Puccinia angustata, which was pub- 
lished in the Bulletin of the Buffalo Society of Natural History, 
volume I, page 67, July, 1873, upon material from “ leaves of 
Scirpus sylvaticum and N. Eriophorum; West Albany and Wat- 
kins, September.” Upon examination of type material, it trans- 
pires that the collection on ” S. sylvaticum” was made at Wat- 
kins, N. Y., and that on S. Eriophorum at West Albany, N. Y., 
and furthermore, that of the two hosts cited only 5 ". Eriophorum, 
collected at Watkins, N. Y., although the second one mentioned, 
bears teliospores that correspond to the description. The other col- 
lection on “ S. sylvaticum,” found to be in reality Y. microcarpus 
{S. rubrotinctus) , bears a distinctly different form of teliospore, 
and must be considered to belong to some other species than P. an- 
gustata. The type of P. angustata Peck is, therefore, the collection 
in the herbarium of the New York State Museum, at Albany, N. Y., 
collected in September [1871?], at Watkins, N. Y., on Scirpus 
Eriophorum, by Prof. C. H. Peck. Thanks are due to Prof. Peck 
for the loan of the type material and for much assistance in ascer- 
taining numerous facts connected therewith. 
4. Puccinia Ellisiana Thiim. — A collection on Andropogon 
sp., made by Dr. J. F. Brenckle, at Kulm, N. D., was used to sow, 
April 9, on Viola cucullata, V. Nuttallii, V. primulac folia, Lacini- 
aria punctata and Lithospermum angustifolium, with infection 
only on the two first named species of Viola. In both cases pycnia 
began to show in abundance May 8, and aecia May 12. 
A number of vain attempts have been made in previous
