Which of the following features is NOT represented in the floral diagram of Allium cepa?

Step-by-step solution

Allium cepa (onion) belongs to the family Liliaceae. In the members of Liliaceae, the calyx and corolla are not distinct and are termed as perianth (tepals). The stamens are attached to the perianth, a condition known as epitepalous, not epipetalous. Therefore, the floral diagram of Allium cepa will show epitepalous stamens. It will also correctly show six tepals arranged in two whorls (3+3), a tricarpellary syncarpous ovary, and axile placentation. Answer: Presence of epipetalous stamens
