Plant Collections Requirements for each Team: Ten (10) plants correctly identified, pressed and mounted. An additional 15 plants correctly identified and pressed or correctly identified and photographed (in power point format). This makes a total of 25 plants required at minimum = “C” grade. “A” and “B” Collection grades will be determined by total number of plant specimens and quality of collection.
