The margins of sepals or petals are overlap one another but not in particular direction.
The margins of sepals or petals are overlap one another but not in particular direction.
Show Hint
When confused between types of aestivation, visualize petal arrangement or use examples like Cassia (imbricate), Hibiscus (twisted), etc.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Twisted: Each petal overlaps the next in one consistent direction — not the case here.
Imbricate: Petals overlap each other, but the direction of overlap is irregular — matches the question.
Valvate: Margins do not overlap but just touch — incorrect.
Vexillary: One large petal overlaps two lateral ones, which in turn overlap the two innermost — specific to papilionaceous corolla.
Imbricate: Petals overlap each other, but the direction of overlap is irregular — matches the question.
Valvate: Margins do not overlap but just touch — incorrect.
Vexillary: One large petal overlaps two lateral ones, which in turn overlap the two innermost — specific to papilionaceous corolla.
