Arrange the following genera in the increasing order of number of carpels in each flower: 1.Abutilon 3.Allium 2.Bauhinia 4.Nicotiana The correct answer is:
A (i) Abutilon belongs to family Malvaceae. Gynoecium is pentacarpellary or polycarpellary, syncarpus but stigma free, so gynoecium is incompletely syncarpous. (ii) Bauhinia belongs to family Fabaceae. Gynoecium is monocarpellary with marginal placentation (iii) Allium belongs to family Liliaceae, (iv) Nicotiana belongs to family Solanaceae. Gynoecium is bicarpellary, syncarpous, ovary superior, biloculor. The decreasing order of number of carpels in each flower is- Bauhinia \(>\) Nicotiana \(>\) Allium \(>\) Abutilon.
