Anise Magnolia – Magnolia salicifolia, Morton Arboretum acc. 327-63*2
Anise Magnolia can grow to 50 feet. Fragrant white flowers 3-4 inches across, made up of 12-18 segments appear in late winter – early spring before leaves emerge. Grows best in moist, well-drained soil rich in humus. Prefers acidic to neutral soil in full sun or partial shade. Anise magnolia has narrower leaves than most magnolias. 
The genus Magnolia contains about 200 species of flowering trees and shrubs, with innumerable cultivars and varieties being developed all the time. Magnolia is an ancient plant lineage, first appearing in the fossil record about 20 million years ago, while evidence of plants in the family goes back to 90 mya .
Having evolved before pollinators in Hymenoptera (bees, wasps & ants) appeared, the progenitors of our modern ornamental magnolias relied on beetles for their sexual gratification. Their large, showy flowers are a direct result of the plant's strengthening its delicate flower parts against the beetle's comparitively "rough handling" while feeding on pollen.

Magnoliaceae – Magnolia Family
The earliest flowering plants date back about 130 million years. According to Cronquist Evolution and Classification of Flowering Plants, the most primitive of all living angiosperms belong to the subclass Magnoliidae. This subclass contains several primitive plant families, including the water-lilies (Nymphaeaceae), and buttercups (Ranunculaceae). Tree Encyclopedia | Tree Index | Magnolia Main
