When the margins of sepals or petals overlap one another without any particular direction, the condition is termed as :
Vexillary
Imbricate
Twisted
Valvate
As we discussed in
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
