A floral diagram is a schematic cross-section through a young flower. [1] It may be also defined as “projection of the flower perpendicular to its axis”. [3] It usually shows the number of floral parts, [Note 2] their sizes, relative positions and fusion.
It can be seen that the flower is hermaphrodite and actinomorphic, pentacyclic (i.e., it has 5 floral whorls) and pentamerous (each cycle is composed of five pieces). The floral diagram is a graphic representation of the arrangement of the floral parts and the arrangement of the different whorls, in a cross section of the flower. Each whorl is ...

Peloria or a peloric flower is the aberration in which a plant that normally produces zygomorphic flowers produces actinomorphic flowers instead. This aberration can be developmental, or it can have a genetic basis: the CYCLOIDEA gene controls floral symmetry.
[1] [6] The flower stem is known as a pedicel, and those flowers with such a stem are called pedicellate, while those without are called sessile. [7] In the angiosperms, the flowers are arranged on a flower stem as an inflorescence. Just beneath (subtended) the flower there may be a modified, and usually reduced, leaf, called a bract.
A Narcissus flower in section. Petals and sepals are replaced here by a fused tube, the corona, and tepals. Reduced gametophytes, three cells in male, seven cells with eight nuclei in female (except for basal angiosperms) [10] The gametophytes are smaller than those of gymnosperms. [11]
