Stage name

Landmarks of morphological

Stage 1

Formation stage of disc floret primordia

Disc floret primordia continued to generate a spiral centripetal pattern

Stage 2

Early-stage corollas lobes formation

The apical part of the floret primordia has further sagged and the corolla begins to form

Stage 3

End-stage of corollas lobes formation

The corollas lobes of disc florets began to form

Stage 4

Early-stage of disc floret elongation

The apical corolla started to expand

Stage 5

The middle stage of disc floret elongation

The apical corolla started to elongate

Stage 6

Stage of disc floret persistent elongation

Floret corolla continuously elongated and expanded
