Which pair demonstrates the syncarpous condition?

• A. Castor and Lemon
• B. Brassica and Hibiscus
• C. Papilionaceae
• D. Cucurbitaceae

Answer: (B)

Syncarpous gynoecium means the carpels are fused to form a single ovary, often with multiple locules and a common style or stigma. Brassica shows this clearly: two carpels fuse to create a single, bicarpellary ovary that forms siliques or siliques. Hibiscus also has a syncarpous ovary, with many carpels fused into one multilocular ovary that bears a common stigma. In contrast, the gynoecia in Papilionaceae and Cucurbitaceae are not fused into one ovary in the same way, so they do not exhibit syncarpous condition. Hence Brassica and Hibiscus are the best examples of syncarpous gynoecium.
