Epipetalous stamens are attached to petals, while Epiphyllous stamens are attached to the base of the receptacle. Which statement is correct?

• A. Both are true
• B. Only Epipetalous is true
• C. Only Epiphyllous is true
• D. Neither statement is true

Answer: (A)

Stamen position relative to other floral parts is what this is testing. Epipetalous stamens are adnate to the petals, so the filament or the whole stamen appears attached to the corolla. Epiphyllous stamens are borne on the base of the receptacle, meaning they arise from the floral axis at the bottom of the tube or cup around the ovary rather than from the petals themselves. Because each term describes a real and distinct way stamens can be attached in flowers, both statements are correct: one describes attachment to petals, the other describes attachment to the base of the receptacle.
