All the following pairing of type of aestivation and its example is incorrect except
Valvate - Cassia
Twisted – China rose, ladyfinger, Calotropis
Imbricate – Cassia and Gulmohar
Vexillary – Pea, bean, Aloe, tulip
Cassia and Gulmohar corolla shows imbricate aestivation. Tulip and Aloe do not show vexillary aestivation. Calotropis shows valvate aestivation.
