AGROSTOLOGY, BIOL 434 and PSPP 454, Fall Semester 2009 (if not already, log into the Desire to Learn system for full course access)
Instructor: Matt Lavin, 339 Plant Bioscience Building
Lecture: Friday,
Labs: Friday,
Office hours: Friday,
Goals of the course:
· Develop a personal collection of grasses and grass-like plants of over 120 species, which will assist you with future identification of grass and grass-like species.
· Develop an ability to identify grass species using taxonomic keys.
· Develop an ability to sight identify the four common North American grass and grass-like plant families, Cyperaceae, Juncaceae, Poaceae, and Typhaceae), the 15 common North American grass tribes, and about 70 common grass genera that are of economic or ecological importance in North America. These tribes and genera include:
Tribe Triticeae: Agropyron, Elymus, Eremopyrum, Hordeum, Secale, Taeniatherum, and Triticum.
Tribe Aveneae: Agrostis, Alopecurus, Avena, Beckmannia, Calamogrostis, Deschampsia, Helictotrichon, Hierochloe, Holcus, Koeleria, Phalaris, Phleum, Polypogon, Trisetum, and Ventenata.
Tribe Stipeae: Stipa and Oryzopsis.
Tribe Meliceae: Catabrosa, Glyceria, and Melica.
Tribe Poeae: Bromus, Cynosurus, Dactylis, Festuca, Lolium, Poa, Puccinellia, Schedonorus, and Vulpia.
Tribe Andropogoneae: Andropogon, Sorghum, and Zea.
Tribe Paniceae: Cenchrus, Dichanthelium, Digitaria, Echinochloa, Panicum, Paspalum, Pennisetum, and Setaria.
Tribe Chlorideae: Bouteloua, Buchloe, Cynodon, Eleusine, Schedonnardus, and Spartina.
Tribe Aeluropodeae: Distichlis.
Tribe Eragrosteae: Calamovilfa, Eragrostis, Muhlenbergia, Monroa, and Sporobolus.
Tribe Aristideae: Aristida.
Tribe Arundineae: Arundo, Cortaderia, and Phragmites.
Tribe Danthonieae: Danthonia.
Tribe Oryzeae: Leersia, Oryza, and Zizania.
Tribe Bambuseae: Arundinaria.
Prerequisites: a background in general botany including some
plant anatomy, morphology, physiology, and basic plant identification (or a
high degree of interest in grasses).

*Lab quiz. Each of the 8 lab quizzes will involve the sight identification of about 15 grass specimens. Any of the species presented during previous labs are candidates for quiz specimens. The lab quizzes will form one-third of your grade (see below).
Grading: Grades will be derived from 2 comprehensive exams each worth one-third of your grade and 7 of the 8 quizzes, which are collectively worth one-third of your grade. The exams and quizzes will comprise short answer questions. The comprehensive exams will each involve the sight identification of about 75 specimens. Primary emphasis will be placed on sight identification of the 4 graminoid families, the 15 grass tribes, and the approximately 70 grass genera listed above. Additional emphasis will be placed on the ecological and taxonomic characteristics of the graminoid plant families, tribes, and genera. Success in this class will be achieved by spending time in the lab and elsewhere looking at as many grass species and specimens as possible and working them through taxonomic keys. The taxonomic keys provided in the lab manual (Grasses of Montana) can be utilized during all tests.
Agrostology labs. Specimens of grass and grass-like species will be provided at a rate of about 12 per week. Important morphological and ecological features of the families, tribes, genera, and species will be emphasized. You have the option of preparing these specimens on 'botany' paper (e.g., taping or gluing them to sheets of paper and making notes with each specimen). You can finish this Agrostology course with a set of 120+ of the most common graminoid species, which can serve as a future reference collection for identification. These collection will not be graded and you can arrange these collection in any manner your see fit. Ideally, you should mount related species on the same page in order to compare species-specific as well as genus-specific diagnostic traits.
Lab manual (please bring to each lab): Grasses of Montana (Cards & Copies now has this PDF on file for those of you who would prefer them to produce your hard copy). Recommended books at the MSU Bookstore: 1) Vascular Plants of Montana, by Robert D. Dorn. Mountain West Publishing. 2) How to Identify Grasses and Grass-like Plants, by H. D. Harrington. Swallow Press.
Recommended lab items for indoor lab sessions:
1. 10X hand lens
2. cutting instrument (e.g., knife, scalpel, razor-blade), dissecting needle, or fine-pointed forceps
3.
4. 100+ sheets of 8-1/2" X 11" heavyweight "Botany" notebook paper for mounting lab specimens with scotch tape or Elmers Glue
