Rapaseed (Brassica napus ssp. oleifera)
Enlarged 12x life-size, 3-part Family:

Brassicaceae
Brassicaceae, formerly known as Crucifereae, is named for its Cross-like (Cruciferous) flower. Unique in the plant world for having 4 petals, Rapaseed does not follow Fibonacci’s sequence.
The fruit of Rapaseed is refined to make Canola oil. With 30-40% high sugar content it makes an excellent source of food for pollinators. Rapaseed is self-fertile, and has shown in testing that pollination with its own pollen results in seeds 19% heavier than pollination from another Rapaseed. Brassicas are unique for containing more agricultural crops than any other family, consisting of Cabbage, Radish, Mustard, Horseradish, Turnips, Kohlrabi, Brussel Sprouts, Broccoli, & Cauliflower. Rapaseed lends itself to teaching the formidable “Triangle of U” concept. One petal is removable for detailed study of the stepal and stamen. A ripe pod, magified 3x life-size is depicted in cross section, removable from base. 11 x 9½ x 14”
