Fall 1998



Professor: Dr. Garrett E. Crow


Department of Plant Biology

Office: G-56 Spaulding Hall

Lab: Herbarium, G-69 Spaulding Hall

Phone: 862-3865




Lecture topics:






This course is intended to be strongly field-oriented. Hands-on experience is vital. Field trips to various aquatic habitats will be conducted—plant materials will be collected and identified in the field and through keying in the lab upon return.

We will be out in the field as much as possible until a killing frost eliminates field work. Then herbarium specimens will be used, studying aquatic plants in systematic groupings.

Term Paper and Oral Report


Each student will be required to prepare a term paper (10-12 pp.) on a topic relating to some aspect of aquatic plants. Oral reports will be presented during the last three weeks on the topic of the term paper. Presentations should be about 30 minutes long. Topics must be approved. A schedule for presentations will be established by November 2.
