Types of Aestivation -

(1) Valvate - when sepals or petals lie very close to each other without over lapping eg: mustard , calotropis

(2)  Twisted Aestivation - when one margin of petal or sepal overlaps the margin of next eg: China rose

(3) Imbricate - When both margins of one of the petals are covered by others & both margins of another one are external eg: Caesalpiniaceae

(4) Quincuncial - when two are inner & two are outer, and one is partly outer & partly inner eg: Ranunculus

(5) vexillary - posterior petal is largest & covers two lateral petal the latter in turn nearby overlap the anterior petal eg: pea
