APPENDIX TO 
TWENTY-FIVE YEARS OP BOTANY IN IOWA. 
Much difficulty has been experienced in securing the data requisite for com- 
plete presentation of this subject. To a letter of inquiry sent to members and 
associates, but fourteen replies came back. The content of these replies is the 
basis of what here immediately precedes. 
The papers reported have been arranged by topic tentatively as follows: 
Bacteriology 9 
Ecology 20 
Economic 20 
Morphology 39 
Mycology 16 
Paleobotany 4 
Taxonomy 130 
Here then are the lists as enumerated. Some are mentioned in more than 
one list, since taxonomy, for instance, may concern mycology, or paleobotany 
be morphological. 
The Bibliography of Iowa Botany for the twenty-five years, 1888-1912, inclusive, 
may be arranged under several separate heads: 
' I. Bacteriology. 
II. Ecology and Physiology. 
III. Economic, not I. or V. 
IV. Morphology. 
V. Mycology. 
VI. Paleobotany. 
VII. Taxonomy; except as in V. 
BACTERIOLOGY.
