1. 1. Obtain a set of "sham" plants created by Dr. Warren Wagner, University of Michigan. Study these plants and then select 10 different characters and record the state for each character in the table. Use this table to prepare a dichotomous key, either indented or bracketed, to these species. Now, can you rewrite your key in the other form?
    
2. For additional practice, prepare a dichotomous key (bracketed or indented) to one of the following sets of terms (or make up your own set of terms):

• Special modifications - tendril, thorn, spine, prickle
• Leaf shape - linear, oblong, lanceolate, ovate, elliptic, orbicular, reniform
• Leaf bases/apex - acute, acuminate, obtuse, rounded, truncate, cordate, oblique, hastate, sagittate, peltate
• Leaf margins - entire, crenate, serrate, doubly serrate, dentate, lobed
• Surface features - glabrous, pubescent, pilose, hirsute, scabrous, tomentose, glaucous
• Bud terminology - bud scale, bud scale scar, stipule scar, leaf scar, vascular bundle scar
• Leaf attachment - basal, cauline, alternate, opposite, whorled
• Leaf attachment - petiolate, sessile, perfoliate, clasping, sheathing
• Stem types - rhizome, stolon, corm, bulb, tuber

3. Prepare a dichotomous key to some of your plants-to-know.
