Floral Formula of Liliaceae
The flowers of the Liliaceae family are actinomorphic, bracteate, hypogynous, complete, and bisexual. The perianth is made up of six tepals in two whorls of three (polyphyllous or gamophyllous), usually fused into a tube, valvate aestivation, and an occasional tepal anterior. The androecium is polyandrous, epiphyllous, has a dithecous, basifixed or versatile, introrse anther, and has six stamens in two whorls (3 + 3). Syncarpous ovary, axile placentation, trilocular, and trifid stigma in a tricarpellary gynoecium

Morphology is the branch of biological science that deals with the study of various external features, relative positions, and forms of various organs of various organisms. It is divided into two categories:
- Internal morphology: It deals with the internal forms of organisms. This type of morphology is further divided into anatomy and histology.
- Anatomy: This type of internal morphology studies the organisms after their dissection and opening of various parts of their organs.
- Histology: These studies the tissues, their structure, and their composition.
- External morphology: It is the study of organisms’ external structures, such as their shape, color, size, relative position, and structure.
