Lecturer: James L. Reveal, Professor. Rm. 4102 H.J. Patterson Hall. Phone 405-1588. Email: jr19@umail.umd.edu. Office Hours: By appointment (from 7 am until 5 pm, M-F; weekends by arrangement). Please arrange through Ms. Terry Olenick, Rm. 1212 H.J. Patterson by calling 405-1588. If necessary, or emailing to to5@umail.umd.edu
Required texts: Lecture texts: Contemporary Plant Systematics, 2nd ed. by Dennis Woodland and PBIO 250 Lecture Notes by J.L. Reveal available on the World-wide Web at http://www.inform.umd.edu/PBIO/pb250/index.html. Laboratory manuals are Vascular Plant Taxonomy Laboratory Manual by H.G. Bedell and Manual of Vascular Plants of Northeastern United States and adjacent Canada, 2nd ed., by H.A. Gleason and A. Cronquist. Optional: Students may wish to obtain Woody Plants of Maryland by R.G. Brown and M.L. Brown and Herbaceous Plants of Maryland by M.L. Brown and R.G. Brown. However, Brown and Brown may not be used during any laboratory quiz or examination, and neither is required.
Course Description, Rationale and Goals: PBIO 250 is a four credit course for second-year students. Two hours of lecture and four hours of laboratory per week. Prerequisite: PBIO100, BIOL 105 or permission of the instructor. An introductory study of plant identification, naming and classification as well as the history of systematics and the role of evolution in systematics. Laboratory emphasis is on knowledge of the major families of vascular plants and on the collection and identification of local vascular plants. The rationale of the course is to provide the student with a basic understanding of the underlying principles of systematics, including modern technological approaches, augmented by an opportunity to gain an understanding of the major groups of vascular plants found throughout the world. The course provides an opportunity to collect native and naturalized plants in the Mid-Atlantic region thereby gaining some knowledge of the local flora while at the same time becoming familiar with the kinds of diagnostic keys that can be used to identify plant material. The goal is to provide the student with a firm foundation for and knowledge of the relationships between and among vascular plants based on evolutionary principles as expressed by systematists. Class participation, especially in laboratory, is essential and expected.
Examinations: Three lecture examinations are scheduled as noted above. Each exam is worth 100 points. Makeup examinations will be allowed only for those individuals who provide a valid, University-approved excuse which can be verified (see Chapter 4 of the Undergraduate Catalog) in writing prior to the expected absence. It is the responsibility of the student to request and schedule a makeup examination. All makeup examinations are essay. Makeups must be arranged within one week of the scheduled exam. All examination begin at the start of the period; persons arriving after the first person completes the examination and leaves the room will not be permitted to take the scheduled exam and must arrange for a makeup. See sample examination questions at http://www.inform.umd.edu/PBIO/pb250/exam.html. Announced, pre-examination review session for lecture and laboratory will be arranged prior to the examination and held at a time and place to be announced.
Laboratory: Attendance is required and taken in all laboratory classes. Any student who fails to attend three or more laboratory classes without a valid, University-approved excuse that can be verified (see Chapter 4 of the Undergraduate Catalog) will receive a failing grade for the entire course. Approximately 15 short, unannounced quizzes will be given during the semester of which the top ten grades will be counted (total 100 points). Three examinations will be held as scheduled. No makeup examination will be given without a valid, University-approved excuse that can be verified (see Chapter 4 of the Undergraduate Catalog) submitted in writing prior to the expected absence. It is the responsibility of the student to request and schedule a makeup examination. Each of the three laboratory examinations will be worth 50 points (total 150 points). Makeups must be arranged within one week of the scheduled exam. All examination begin at the start of the period; persons arriving after the first person completes the examination and leaves the room will not be permitted to take the scheduled exam and must arrange for a makeup. The Laboratory syllabus is at http://www.inform.umd.edu/PBIO/pb250/labr.html.
Plant Collection: A plant collection is required. Detailed instructions are provided at http://www.inform.umd.edu/PBIO/pb250/coll.html; any modifications will be presented later in the semester. A collection of 25 dried, labeled and correctly identified plants is required and due by 5 pm on 13 May 1997. The collection is worth 50 points. All collections become the property of the Norton-Brown Herbarium.
Grading: Final letter grades are based on comparative performance established by scores received on scheduled lecture and laboratory examinations, unannounced laboratory quizzes, and the successful completion of the plant collection requirements. The instructor reserves the right to give unannounced lecture quizzes worth no more than 50 points which would then increase the total point value for the course by the corresponding amount. Regardless of the points earned, failure to attend laboratory can result in a failing grade for the entire course.
Academic Dishonesty: Students are reminded that they are subject to the University's Code of Academic Integrity.
