Dilleniaceae http://www.botany.hawaii.edu/faculty/carr/dilleni.... Dilleniaceae are trees, shrubs or occasionally vines comprising 10 genera and about 350 species. The leaves are simple and alternate, the stipules are absent or wing-like and adnate to the petiole. The flowers are actinomorphic and are bisexual or rarely unisexual. The perianth consists of 5 imbricate sepals and usually 5 imbricate petals. The androecium consists of numerous, distinct or fascicled stamens. The gynoecium comprises several distinct, simple pistils, each with a superior ovary and a single locule containing 1-many ovules. The fruit is a follicle or is berrylike.

Rosaceae are trees, shrubs and herbs comprising about 100 genera and 3,000 species. Most species have alternate leaves and stipules. These may be adnate to the petiole. You have likely heard the saying, "a rose is a rose is a rose," suggesting that when you've seen one, you've seen them all. The family does tend to have somewhat monotonous actinomorphic flowers, commonly with 5-parted perianth and numerous stamens. However, closer inspection reveals that the gynoecium varies tremendously among different species of the family. In the subfamily Rosoideae many apocarpous pistils mature into achenes while in the Prunoideae a single monocarpellate pistil matures into a drupe. In subfamily Spiraeoideae the gynoecium consists of two or more apocarpous pistils that mature into follicles. In all of these cases the ovary is superior and there is commonly some development of a perigynous zone. However, in a fourth subfamily, Maloideae, the ovary is compound and inferior, and an epigynous zone may occur. Each "thumbnail" image below is linked to a larger photograph.
