LECTURE EXAMS:

NOTE: Lecture exams are not cumulative.

LAB EXAMS:

For each misspelled botanical name 0.5 points will be deducted from laboratory exam score(s). All laboratory exams are cumulative. These examinations require identification from cut specimens, plant pressings, landscape plants and slides, as well as requiring a command of taxonomic nomenclature. Students will be held responsible for only those species, varieties, forms and cultivars seen during prior labs.

MAKEUP TESTS:

Illness: Arrangements for a makeup of a lecture test must be made within 24 hours of missed exam. A signature of attending physician or nurse is required. Time for the makeup will be at the mutual convenience of instructor and student. Tests not taken earn 0 points.

FIELD TRIPS:

These are tentative dates and times. Check with instructor about any modifications

This course requires one Saturday field trip. All field trips will be conducted rain or shine! Please dress appropriately.

The first Saturday field trip will be on October 1 at 8:00 a.m. to the Washington National Cathedral. National Cathedral is located on the corner of Massachusetts and Wisconsin Avenues, N.W., Washington, DC 20016-5098
Tel: (202) 537-6200.

Information about the second field trip will be given in class.

The third field trip will be on October 29 at 9:00 a.m. to Dumbarton Oaks. Dumbarton Oaks is located at Dumbarton Oaks, 1703 32nd Street, NW, Washington DC 20007. Students from both sections are welcome to attend. Specific directions will be given out in class.

MAKEUP FIELD TRIPS:

You will be allowed to makeup for the field trips. If you are not able to attend a field trip on the assigned day, you have the option of making up the field trip by submitting a special project. Possible options include:

1) Handing in either three additional plant pressings.

2) Submitting six different dried fruit samples – properly prepared and identified.

All samples must be appropriately labeled to receive full credit.

3) Three hours of service in Landscape Technology Demonstration Gardens/Greenhouse.

OTHER:

If absence from a scheduled exam is necessary for religious observance or for participation in Montgomery College activities at the request of Montgomery College authorities, the instructor must receive notification one week prior to the schedule exam or the right to a makeup is forfeited.

Classroom Policies

Attendance:

Attendance is expected for each of the classes and required field trips.

Academic honesty:

Students cheating on lecture or lab exams will receive a failing grade for that exam.

Classroom conduct:

The use of cell phones during lectures or exams is not allowed. Use of portable recording devices is not allowed in class unless students receive approval from the professor.

Any student who may need an accommodation due to a disability, please make an appointment to see me during my office hour. A letter from Disability Support Services (R-CB122; G-SA175; or TP-ST120) authorizing your accommodations will be needed. Any student who may need assistance in the event of an emergency evacuation must identify to the Disability Support Services Office; guidelines for emergency evacuations for individuals with disabilities are found at: www.montgomerycollege.edu/dss/evacprocedures.htm.

Cancellation of classes:

Class cancellation due to extreme weather conditions will be announced on local radio stations like WTOP and WMAL.

Course schedule:

The first week: Introduction to the course, syllabus, project, field trips, text, etc. and review fundamentals of plant identification.

The following weeks till the end of the semester: Review the plants on the plant list in sequential order.

PROJECT:

The project involves collecting 10 different plant specimens. Students are limited to exterior ornamental plant material. You may submit more than ten pressings but you will only be graded on your ten best samples. All samples submitted must have sufficient size and have plant parts present to enable plant identification but small enough to fit on to herbarium paper (16 ½ “x 11 ½ “).

Plant specimens should be pressed and properly identified. Use the specimen labels provided in class or create your facsimile. The following information must be typed out on each specimen label and placed in the lower right hand corner of the plant pressing. . Five points will be taken off for samples that are not typed!

EXAMPLE ‑ SPECIMEN LABEL:

Herbarium of No. #1

Montgomery College

Botanical Name: Quercus alba September 9, 2002

Common Name: White Oak

Family: Fagaceae

Location: Wheaton, Maryland. Habitat: Home landscape

Collected and identified by: Carol von Linne

Each of the samples should be submitted between sheet of newspaper with its specimen label. DO NOT COVER pressings with plastic wrap, wax paper, etc.

If permits selected plant samples will be permanently mounted at the college during lab.

IMPORTANT!

Ų Students are required to have two samples from the “Wish List”. An updated “Wish List” will be given out each semester during class.

Ų Don't forget to identify each sample with a sample number. Please remember to fill out and hand in the project grade sheet (see attached) with your project.

If you have any questions please ask them and/or refer to the examples of pressings in Room 240 SA. Have fun!

Guidelines for Project

GOOD PLANT PRESSINGS

When you clip a sample from a plant for a pressing, you should include: leaves showing characteristic features, flowers if possible, and enough twig or stem to show lenticels, leaf scars, leaf and flower buds, and pith. Do not try to press fruits, nuts, or berries in your press or you will make a mess. To keep the pressings as flat and as clean as possible, any fruit from a specimen should be put in a bag or small container. If you have a large twig you can take a razor or sharp knife to split it in half and then lay out the cut piece to show the pith. When you put the sample into your plant press, place it so that both the upper and lower surface of leaves can be seen. If possible, cut open the flower of a pressing to display its parts (petals, stamens, and ovary ‑ the best keys for identification). Make sure to number each specimen and write down all the information you will need for the label before you press it. This will avoid any confusion between different specimens and make it easy for you to mount them when they have dried completely. Once in the press, specimens need 8 days or longer to dry completely. A wet or moist pressing will rot, mold, and lose its color when mounted on paper.

When making the labels for your specimens, it is a good idea to write them out on index cards before typing. Under "Herbarium of" type Montgomery College. Indicate the number of the specimen after No. The first plant you collect in your life is plant number one, the second number two, etc. Even if you do not use or mount a plant it is still number two. Officially, you should keep a record of the plants you collect and keep a tally of the numbers. There are professionals who are at this moment collecting number 23,456 in their collection, so keep track. For the technical name, type the genus then the specific epithet. The first letter of the genus is capitalized with all following letters in lowercase. All of the letters of the specific epithet are lowercase. THE GENUS AND THE SPECIFIC EPITHET ARE ALWAYS UNDERLINED. Example:

Cornus florida The genus and specific epithet

together make the SPECIES NAME.

A variety or a cultivar name sometimes follows the genus and the specific epithet (species). A variety is a group of plants, which display a unique character, which differentiates it from the species. Most of the seedlings (80%‑90%) of varieties will display the unique characteristics of their parents but some will revert back to the regular species form.

Example:

Cornus florida var. rubra The variety indicated by var.

and the name underlined.

A cultivar is essentially a cultivated variety. A cultivar, which is brought about through selective cultivation and breeding, then continued through cuttings, grafting, or continual crossing of the parent types which produced the cultivar. The seeds of cultivars are not true to type (their parents) as varieties are.
