Sympetalae

Sympetally (fused
petals) is a flower characteristic that historically was used to classify a grouping of plants termed Sympetalae, but this term has been abandoned in newer molecular based classifications, although the grouping has similarity to the modern term asterids
.
History
Sympetalae
Prior to the
dicots, and then divided them into Pentacyclicae and Tetracyclicae in accordance with the number of flower parts in each group, four and five respectively.[6]
According to Engler and Prantl, Sympetalae includes the following orders:
Campanulatae.[7]
Sympetalous flowers are found in many angiosperms, but it was the combination of sympetally with a "stamen whorl isomerous and alternate with the corolla-lobes, or stamens fewer than the corolla lobes" that
