Aestivation Types Descriptions A. Valvate 1. Sepals or petals overlap each other but not in a particular direction B. Twisted 2. Sepals or petals just touch each other at the margin without overlapping C. Imbricate 3. Largest petal overlaps lateral petals, which overlap the smallest anterior petals D. Vexillary 4. One margin of the appendage overlaps that of the next one
Options
- AA - 2, B - 4, C - 1, D - 3
- BA - 1, B - 4, C - 2, D - 3
- CA - 2, B - 3, C - 4, D - 1
- DA - 1, B - 2, C - 4, D - 3
Correct answer
A. A - 2, B - 4, C - 1, D - 3
Step-by-step solution
Valvate aestivation has sepals or petals just touching each other at the margin without overlapping. Twisted aestivation has margins overlapping one another. Imbricate aestivation involves overlapping in no particular direction, and vexillary (or papilionaceous) involves a specific overlapping pattern of petals
