Anacardiaceae- Cashew Family

Rosaceae By:Jaclyn Kuklock. Rose Flower There are 5 sepals united at the base, 5 petals rising from the top of a saucer- like structure, numerous stamens.

Flowering plants have unique adaptations that allow them to dominate in today’s world.

Angiosperms have seeds enclosed in some type of fruit.

C: Magnoliopsida SC: Delleniidae O: Primulales F: Primulaceae “Primroses” 1. Mostly perennial herbs. 2. Leaves opposite, whorled or basal.

Definition: the fruit is the whole product of the development of the gynaecium as a result of fertilization. Sometimes other parts of the flower in addition.

Class: Magnoliopsida Order: Lamiales Family: Verbenaceae

What is the floral part?. Sepals = Calyx Receptacle.
