It depends on other branches of botany for good information like anatomy, cytology, physiology, phytochemistry, genetics, embryology, ecology etc. He divided the Plant kingdom into 2 Subkingdoms, viz. Magnoliidae These are mostly woody trees and shrubs and all are regarded as the most primitive of the Angiosperms in general.

    Apart from some other structural features of importance, the classification of Angiosperms rests mostly upon the structure of the flower, which is undoubtedly their most distinctive feature. According to Davis and Heywood the classification is achieved in four 4 different consecutive phases: 1. Consolidation Phase: In this phase, plant is studied both in field as well in the herbarium and a range of variations are evaluated. The result was a large number of systems see List of systems of plant taxonomy. This treatment of the older Liliaceae meets with the approval of most modern botanists.

    This trend reaches its height of perfection in the Dipsacales, the Umbelliferae [Apiales] and above all in the Asterales. The inflorescence of daisies therefore give the appearance of a raceme that has been compressed downwards forcing all the individual flowers to become pressed tightly into a side by side arangement on a flat head [e.
