2. The number of sepals, petals, whether they are fused or free and the aestivation
3. The number of stamens, free or fused and their attachment to other floral parts
4. The number of carpels, free or fused and the placentation

The floral diagram (a diagrammatic representation of the flower) shown in the image belongs to the family Liliaceae.


It can be identified based on the number of floral appendages. The family Liliaceae includes plants with trimerous flowers. The floral appendages in trimerous flowers are 3 or in sets of three. The perianth consists of 6 tepals arranged in two whorls of three each and they are fused. They show valvate aestivation. There are six stamens and are attached to tepals, this is called epiphyllous condition. The innermost whorl of gynoecium shows tricarpellary condition, the ovary is superior, trilocular with axile placentation.
