The Botany Nomenclature Set is an excellent way for students to learn the names of various parts of a plant, leaf or flower.  The set includes three pairs of large plastic cards measuring 22 cm x 22 cm each, which show the parts of a plant, leaf and flower in labeled and unlabeled versions.  For each pair there is a corresponding set of smaller label cards measuring 6.5 cm x 3 cm with the part names on one side and a pictogram of the related item (plant, leaf, flower) on the other side.  The entire set comes in a compartmentalized box with a lid, measuring 29.5 cm x 25 cm x 2.5 cm.  This set makes an excellent accompaniment to the Tree, Leaf and Flower puzzles.
