IOWA ACADEMY t)F SCIENCE 
When we turn to mycology pure and simple we have abundant material at 
our disposal. Professor Arthur began by publishing in Iowa his famous re- 
searches on the rusts, and during all these years papers on rusts and smuts- 
have been issuing from our State College laboratories in number too great for 
present citation. He and Mr. Holway have at the same time issued several- 
volumes of exsiccati in the same group. Professor Pammel and Miss King, Dr. 
Buchanan, Dr. Hume, and others have made applied botany at Ames renowned, 
and many of the pages of our reports tell of their ever increasing industry. 
Dr. Buchanan has furthermofe placed all students of fresh water algae in Iowa 
and the entire northwest under obligations by his most convenient descriptive 
key to these difficult microscopic plants. 
Professor G. W. Wilson, now of North Carolina, published from Fayette 
several important mycological papers, among them those of chief importance 
are the “Studies of the North American Peronosporales'’ Professor Fink, now 
of Oxford, Ohio, in a long series of papers, ending in that on the Lichens of 
Minnesota, as a contribution of the -United States National Museum Series, has 
reviewed not the lichens of Iowa only, but virtually those of the entire country. 
Mr. J. P. Anderson, formerly of Lamoni, has given us a descriptive list of the 
Erysiphales which, within the limits set, is certainly as carefully prepared and 
as discriminating as anything we have in English; and Dr. Hume, now of 
Florida, has published a preliminary sketch of the mycologic flora of distant 
Colorado. Dr. A. S. Beach has given us a book on the diseases of the bean, 
and Professor Frederick Rolfs a paper on Corticium vagans, a new disease of 
the potato. Mr. F. J. Seaver, now of Bronx Park, New York, has published a 
book describing all known Iowa Discomycetes, and more recently a second vol- 
ume on the Hypocreales of North America. Your present historian has placed 
upon the record an account of some of the saprophytes, polypores, mushrooms, 
puff-balls of the state and has endeavored so far as he might to set in order for 
the continent the notorious slime-moulds. 
Turning now to morphological research we have some thirty titles. When 
we reflect that all work in this line must perforce take origin in the relatively 
few laboratories of Iowa, the list is creditable indeed. • At the State College, 
Mr. Stewart, Miss Sirrine, and Miss Emma Pammel (the lamented Mrs. Hansen) 
have considered the structure of leaves; Miss Bigelow, the glands of Ptelea; 
Mr. V/eaver, the spores of ferns; Dr. Buchanan and Mr. Faurot, the styles of 
the composites; Miss Fogel (Mrs. Buchanan), the morphology of roots; and 
Dr. Pammel and Misses Sirrine and Robb, the histology of the coverings of 
certain seeds. 
Professor Conard has published studies in the histology of ferns, and the 
spore-formation of Ly cogala; Mr. Hawkins is the author of an article on the 
sporangium of Equisetum, and Professor Wylie on the Morphology of Eloclea; 
while Professor Gow has given account of karyokinesis in corn, and has pub- 
lished studies of the aroids; and Mr. Knupp has illustrated for our pages the 
flowers of Myriophyllum. Professor Frye, now of Washington, has a paper on 
the embryo-sac of Casuarina; and Professor Fink an article on the pollination 
of the tomato. The present writer has described the grosser structure of the 
Dakota cycads and some features of their histology. He has also given account 
of a number of fossil stem-fragments gathered from our Iowa drift. Some
